<hr />
<div>2006-04-06 22h43 Norz: Hi! Best wishes to you & Vorbis! :)<br />
<br />
==Deletion Articles==<br />
<br />
So, my templates that the community has mostly used and help give an overview of articles are "stupid". Okay, fair game. The articles [[Ableton Live]], [[Ardour]]... are stupid. Stop making them.<br />
<br />
Polite, isn't it? {{User:Elliottmobile/sig2}} 03:22, 2 October 2006 (CDT)<br />
<br />
They are "stupid" in a sense that HA does no co-exist on the large scale that wikipedia does. Some of your templates are useful, but we have no use for your templates and the fact that you wish to enforce them on others. This is the only way you are making contributions to the wiki. Quite frankly it's annoying our wiki editors, my self included. Maybe you care to actually write some pages? yes? When Beto contributed the Software Infobox to the community he did it out of necessity. HA does not run things in the same manner the way wikipedia does. It's based upon the best interest of the community at hand. Are References necessary for pages? yes? can we expand the wiki based upon the particular interest of the community as a whole? yes? we can. Do we need to strictly enforce rules on a grand scale? no. There are only four to five dedicated user that make contributions to our wiki anyhow do the due to the time needed and the technical skills required to translate complicated matters into plain english. --[[User:HotshotGG|HotshotGG]] 16:19, 2 October 2006 (CDT)<br />
<br />
[http://wiki.hydrogenaudio.org/index.php?title=Special%3AContributions&offset=0&limit=50&target=Elliottmobile&namespace=0 A list of all my article-only contributions.] All I contribute is templates, now? {{User:Elliottmobile/sig2}} 14:59, 2 October 2006 (CDT)<br />
<br />
You are just moving stuff around and maintaining things from what I can tell by those edits. You are just contributing to the templates/maintenence nothing else. If you are only job is police the wiki like, such expect to recieve more critisism. You single handledly violated the wiki policy anyway, by interjecting personal opinion into a page that was unecessary. Save your opionions for your own personal user page and respect other people space. Once you have done so I will be a little more polite. I think a few others would agree. --[[User:HotshotGG|HotshotGG]] 17:25 2 October 2006 (CDT)<br />
<br />
#That was before policy even existed here.<br />
#Point me to the mystical "few others" you talk about, please.<br />
{{User:Elliottmobile/sig2}} 06:02, 3 October 2006 (CDT)<br />
<br />
Canar for example. It's very simple stay off my case and don't violate your own policies. --[[User:HotshotGG|HotshotGG]] 16:26, 4 October 2006 (CDT)<br />
<br />
Apart from you, there's Canar. So, other, not others. {{User:Elliottmobile/sig2}} 03:41, 4 October 2006 (CDT)<br />
<br />
I am through aruging about this, but the bottom line is you don't run this wiki. Jan is the only adminstrator here in charge of it. Stop being a pompous asshole acting like you do. It's a community wiki. --[[User:HotshotGG|HotshotGG]] 16:19, 6 October 2006 (CDT)<br />
:But isn't it funny how you force your viewpoint, contradicting yourself? Community wiki, indeed. {{User:Elliottmobile/sig2}} 06:03, 7 October 2006 (CDT)</div>Elliottmobilehttps://wiki.hydrogenaudio.org/index.php?title=Vorbis&diff=14813Vorbis2006-10-07T10:56:14Z<p>Elliottmobile: You know, apart from the fact that we use it and all.

'''Vorbis''' (commonly used inside the [[Ogg]] container) is a fully open, non-proprietary, patent-free (subject to [http://www.hydrogenaudio.org/forums/index.php?showtopic=13531 speculation]), and royalty-free, general-purpose compressed audio format for mid to high quality (8khz-48.0kHz, 16+ bit, [[multichannel]]) audio and music at fixed and variable bitrates from 16 to >256 kbps/channel. This places vorbis in the same competitive class as audio representations such as MPEG-4 ([[AAC]]), and similar to, but higher performance than [[MP3]], TwinVQ ([[VQF]]), [[WMA]] and [[PAC]]. Vorbis is the first of a planned family of Ogg multimedia coding formats being developed as part of Xiph.org's ogg multimedia project.<br />
<br />
Informal listening test suggests Vorbis to be comparable to MPEG-4 [[AAC]] at most bitrates and [[MPC]] at 128 kbps. Transparency is generally reached at about 150-170 kbps (-q 5) (with some exceptions). The encoder is reasonably young and unoptimized, so further improvements can always be expected.<br />
<br />
Unfortunately, Xiph.org has failed to improve Vorbis at a steady rate since its initial 1.0 release in July 2002 (due to other developement projects and time constraints). Since then development has been led by other coders such as [http://sjeng.org/vorbisgt3.html Garf] and [http://www.geocities.jp/aoyoume/aotuv/ Aoyumi]. Aoyumi's '''[[aoTuV]]''' series of encoders was incorporated into the September 2004 release of 1.1, which brought about the first quality improvements across the board for 2 years. Currently Aoyumi is working on aoTuV Beta 5 and future releases. The latest version is aoTuV Release 1, which is the re-branded Beta 4.51 (released in December 2005). Unfortunately, the improvements of aoTuV Release 1 has not been incorporated yet into the 'official' Vorbis line.<br />
<br />
Vorbis has had success with many recent video game titles employing Vorbis as opposed to MP3 (with Epic Games' Unreal Tournament 2003 and Unreal Tournament 2004, the PC port of Microsoft's Halo and Uru being notable examples). Ogg Vorbis is also an official part of the [http://www.openal.org/extensions.html OpenAL] API extension library, used in many popular [http://www.openal.org/titles.html computer games]. On April 10, 2006, [http://www.radgametools.com/ RAD Game Tools] integrated Ogg Vorbis support to their Miles Sound System (MSS), which has been used in over 3,200 games worldwide. This ensures that future games utilizing MSS will have the capability to play Ogg Vorbis files. Check out [http://wiki.xiph.org/index.php/Games_that_use_Vorbis xiph wiki] for a full list of games confirmed to use Ogg Vorbis. <br />
<br />
'''Before encoding files using Ogg Vorbis, check out the [[Recommended Ogg Vorbis|Recommended Ogg Vorbis article]] to determine what encoder to use and what settings are recommended by Hydrogenaudio.'''<br />
<br />
==Pros==<br />
* Ogg Vorbis specification is in the public domain; it is free for commercial or noncommercial use, under both (LGPL and BSD licenes)<br />
* Easy to use high-level API (Application Programming Interface)<br />
* Good all-round performance (>48 kbps - a leading codec at [http://www.rjamorim.com/test/multiformat128/results.html 128 kbps])<br />
* Well written [http://www.xiph.org/ogg/vorbis/docs.html specs]<br />
* Supported by most portable [[Ogg Vorbis#Supporting Digital Audio Players|DAPs]]<br />
* Suitable for internet-streaming (via [http://www.icecast.org/ Icecast] and other methods)<br />
* Fully [[gapless]] playback<br />
* High potential for further tuning<br />
* Structured to allow the design for a hybrid filterbank<br />
<br />
==Cons==<br />
* Limited official development (third-party developement is always encouraged)<br />
* Current implementations are more computationally intensive to decode than MP3<br />
* Multichannel input mappings for 5.1, Ambisonic-B, and other configs have no channel coupling and aren't tuned (expect sub-optimal results until code is improved)<br />
<br />
==Technical Information==<br />
* Multiple block sizes for window switching including overlap (powers of two only) ''(128/1024, 256/2048, 512/4096)''<br />
* Customly designed [[window function]] is applied similiar to the sine window. it has (good sidelobe rejection) <br />
:<font size="8pt"><math>w_k = \sin{(\frac{\pi}{2} \cdot sin^2[(\pi\div2n \cdot (k+0.5))]}</math></font><br />
* Psychoacoustics masking is exploited via an ([[ATH]] model)<br />
* Masking curves are computed from an ''emperically'' adjusted set of [http://www.zainea.com/masking2.htm Ehmer Curves]<br />
* Modified Discrete Cosine Transform ([[MDCT]]) is used for noise analysis<br />
* Fast Fourier Transform ([[FFT]]) is used for tonal analysis<br />
* Global masking curve is a mixture between calculated FFT+MDCT curves and ATH curves overlayed<br />
* Floor 1 or the noise-floor (envelope) is calculated using the global masking curve & piecewise linear approximation divided by spectrum to generate the residue (fine detail). The Levinson-Durbin [http://www.data-compression.com/speech.html#ana LPC model] in Floor 0 is no longer used, however the code still exists<br />
* [[Noise normalization]] is applied to compensate for energy lost in certain frequency bands due to quantization (rounding). <br />
* The channels are [[channel coupling|coupled]] ''strictly'' by residue using ([http://us.xiph.org/ogg/vorbis/doc/stereo.html point/phase stereo] and lossless)<br />
* Multistage [[Vector quantization]] is used for coding the noise-floor and residue backend using ''trained'' codebooks.<br />
* [[Huffman coding]] is used to minimize vector codeword redundancy<br />

'''LAME''' (Lame Ain't an MP3 Encoder) is the [[Hydrogenaudio]] recommended [[MP3]] encoder. It has been developed by the open-source community since 1998, and has become the highest quality [[MP3]] encoder for most purposes.<br />
<br />
Some benefits for using LAME:<br />
* Highly optimised presets<br />
* Fast encoding<br />
* [[CBR]], [[ABR]] and [[VBR]] encoding methods<br />
* [[Gapless]] playback with LAME-header compliant decoders<br />
* [[Exact Audio Copy]] and [[CDex]] support<br />
<br />
<br />
==History==<br />
LAME development began around mid-1998. Mike Cheng started it as a patch against the 8hz-MP3 encoder sources. After some quality concerns raised by others, he decided to start from scratch based on the dist10 sources. That branch (a patch against the reference sources) became LAME 2.0, and only on LAME 3.81 they got rid of all dist10 code, making LAME a completely new program-not a mere patch of an existing encoder.<br />
<br />
The project quickly became a team effort. Mike Cheng eventually left leadership and started working on [http://toolame.sourceforge.net/ tooLAME], an [[MP2]] encoder. Mark Taylor became leader and released version 3.0 featuring gpsycho, a new psychoacoustic model developed by him.<br />
<br />
Nowadays LAME is considered the best MP3 encoder at mid-high bitrates and features the best VBR model among MP3 implementations, mostly thanks to the dedicated work of talented developers like Takehiro Tominaga, Naoki Shibata, Darin Morrison, Gabriel Bouvigne, Robert Hegemann, etc. And development is still going on...<br />
<br />
<br />
==Recommended encoder compiles and source code==<br />
This list will be kept up to date with the current LAME compiles that are recommended for optimal quality and will keep track of any development compiles released on [[Hydrogenaudio]].<br />
<br />
It is suggested that the compiles available here be used with the [[#Recommended encoder settings|recommended encoder settings]].<br />

==Recommended encoder settings==<br />
This section describes the [[Hydrogenaudio]] recommended settings to be used with [[LAME]] for highest quality [[MP3]] encoding.<br />
<br />
These settings require LAME 3.94 or later. LAME 3.97 is the recommended version.<br />
<br />
Avoid using alpha (a) versions of LAME. More often than not those are exclusively for testing purposes. Use them only if you want to help developers with feedback. History of [http://www.hydrogenaudio.org/forums/index.php?showtopic=28125/ Lame versions & compiles].<br />
<br />
<br />
'''Note #1:''' the rule of thumb when considering encoding options: at a given bitrate, [[VBR]] is higher quality than [[ABR]], which is higher quality than [[CBR]] ([[VBR]] > [[ABR]] > [[CBR]] in terms of quality). The exception to this is when you choose the highest possible [[CBR]] bitrate, which is 320 kbps (-b 320 = --alt-preset insane), but this produces very large filesizes for very little audible benefit.<br />
<br />
'''Note #2:''' all modes and settings mentioned in this topic belong to the specifications of the [[MP3]] standard, and the resulting MP3s should be playable by every [[MP3]] decoder that conforms with the standard. If your decoder or device does not play MP3s produced by LAME, blame the manufacturer or developer, and not LAME.<br />
<br />
===VBR (variable bitrate) settings===<br />
'''[[VBR]]:''' ''variable bitrate mode. Use variable bitrate modes when the goal is to achieve a fixed level of quality using the lowest possible bitrate.''<br />
<br />
[[VBR]] is best used to target a specific quality level, instead of a specific bitrate. The final file size of a [[VBR]] encode is less predictable than with [[ABR]], but the quality is usually better.<br />
<br />
'''Usage:''' <code>-V(number)</code> where number is 0-9, 0 being highest quality, 9 being the lowest.<br />
<br />
'''Example:''' <code>-V2</code><br />

See also [[#Technical information|Technical details for recommended LAME settings]].<br />
<br />
If you need a predictable bitrate (in a streaming application, for example), use [[ABR]] or [[CBR]] modes, described below.<br />
<br />
===ABR (average bitrate) settings===<br />
'''[[ABR]]:''' ''average bitrate mode. A compromise between [[VBR]] and [[CBR]] modes, [[ABR]] encoding varies bits around a specified target bitrate.''<br />
<br />
Use [[ABR]] when you need to know the final size of the file but still want to allow the encoder some flexibility to decide which passages need more bits.<br />
<br />
'''Usage:''' <code>--preset <bitrate></code> where <bitrate> (desired averaged bitrate in kbit/s) can be any value between 8 - 320 , like eg. 9, 17, 80, 128, 133, 200 etc.<br />
<br />
'''Example:''' <code>--preset 200</code><br />
<br />
'''Important:''' ''[[ABR]] setting is tuned from 320 kbit/s down to 80 kbit/s.''<br />
<br />
===CBR (constant bitrate) settings===<br />
'''[[CBR]]:''' ''constant bitrate mode. [[CBR]] encoding is not efficient. Whereas [[VBR]] and [[ABR]] modes can supply more bits to complex music passages and save bits on simpler ones, [[CBR]] encodes every frame at the same bitrate.''<br />
<br />
[[CBR]] is only recommended for usage in streaming situations where the upper bitrate must be strictly enforced.<br />
<br />
'''Usage:''' <code>-b <bitrate></code> where <bitrate> (bitrate in kbit/s) must be chosen from the following values: 8, 16, 24, 32, 40, 48, 64, 80, 96, 112, 128, 160, 192, 224, 256, or 320.<br />
<br />
'''Example:''' <code>-b 192</code><br />
<br />
'''Important:''' ''[[CBR]] setting is tuned from 320 kbit/s down to 80 kbit/s.''<br />
<br />
===Remarks===<br />
The <code>--vbr-new</code> switch enables the new [[VBR]] mode. Lame will encode much faster than the old/default [[VBR]] mode. In terms of quality, <code>--vbr-new</code> appears to be better than the old model, but reports of artifacts when using the new model do exist. Despite these possible issues, <code>--vbr-new</code> is currently recommended over the default [[VBR]] mode due to both the speed and quality increases afforded by the new algorithm.<br />
<br />
'''-mm''' : the sound will be encoded in '''mono'''. Eg. useful for low bitrates & when stereo is less important.<br />
<br />
===Quick start===<br />
====Best quality: <font style="color:red">"archiving"</font>====<br />
<br />
<code><font style="color:red">-b 320</font></code>. This is the strongest setting for [[MP3]], with the lowest risk of [[artifact]]s.<br />
With the exception of a few situations, quality is rarely better than the highest [[VBR]] profiles described below. However, 'archiving' music using a lossy format like [[MP3]] is never recommended &ndash; no matter how transparent the resulting files might be.<br />
The alternative is to use [[Lossless]] formats like [[WavPack]], [[FLAC]] etc. that allow true archiving bit for bit like on original CD.<br />
<br />
====High quality: <font style="color:green">HiFi, home or quiet listening</font>====<br />
<br />
<code><font style="color:green">-V3 --vbr-new</font></code> (~175 kbps), <code><font style="color:green">-V2 --vbr-new</font></code> (~190 kbps), <code><font style="color:green">-V1 --vbr-new</font></code> (~210 kbps) or <code><font style="color:green">-V0 --vbr-new</font></code> (~230 kbps) are recommended.<br />
These settings will produce [[transparent]] encoding (transparent = most people cannot distinguish the [[MP3]] from the original in an [[ABX]] blind test).<br />
Audible differences between these presets exist, but are extremely rare.<br />
<br />
====Portable: <font style="color:purple">background noise and low bitrate requirement, small sizes</font>====<br />
<br />
<code><font style="color:purple">-V6 --vbr-new</font></code> (~115 kbps), <code><font style="color:purple">-V5 --vbr-new</font></code> (~130 kbps) or <code><font style="color:purple">-V4 --vbr-new</font></code> (~160 kbps) are recommended for this use.<br />
<code><font style="color:purple">-V6 --vbr-new</font></code> produces an acceptable quality, while <code><font style="color:purple">-V4--vbr-new</font></code> should be close to perceptual [[transparency]].<br />
<br />
====Very low bitrate, small sizes: <font style="color:blue">eg. for voice, radio, [[mono]] encoding etc.</font>====<br />
<br />
For very low bitrates, up to 100kbps, [[ABR]] is most often the best solution. <br />
Use <code><font style="color:blue">--abr <bitrate></font></code> (e.g. --abr 80).<br />
<br />
'''--preset voice''' is only available in the command line front-end, and is there for compatibility.<br />
It is currently mapped to '''''--abr 56 -mm''''', so that means that the recommendation would be to encode in mono, and use ABR. <br />
<br />
<br />
[[Image:lame-chart-2.png|frame|center|Here a trial to get a view, how the <font style="color:red">perceived listening quality</font> improves with settings/<font style="color:blue">averaged filesize</font>]]<br />
<br />
<br />
====Hey! What happened to "--alt-preset"?====<br />
<br />
The revolutionary <code>--alt-preset</code> system was introduced in LAME 3.90; it was replaced by the <code>--preset</code> flags in later versions. Starting with version 3.94, the <code>-Vx</code> quality system was introduced, which allows finer control over the desired bitrate; the <code>--preset</code> switches were made into aliases to the corresponding <code>-V</code> flags for the sake of backwards compatibility. '''There is no difference between the output you get if you use <code>-V2</code> or <code>--alt-preset standard</code>.''' (Although adding <code>--vbr-new</code> is recommended for now, see above for details.)<br />
<br />
More encoding options are available under the new system, such as <code>-V1</code>, which provides a level of quality between the old "standard" and "extreme" presets, or <code>-V3</code>, which is between the old "medium" and "standard" presets.<br />
<br />
LAME 3.97 features more streamlined command line options, and it's recommended to stick to one of the values described in the text or shown in the tables above. <font style="color:blue">You don't need to worry</font> anymore about quality, settings, arcane combinations of switches, or presets.<br />
<br />
For example, the following command lines will all produce the same output:<br />
<br />
<code>--alt-preset insane</code> = <code>--preset insane</code> = <code>-b 320</code> = <code>--preset 320</code> = <code>--preset cbr 320</code><br />
<br />
(<code>--preset cbr 320</code> is the exact same thing as <code>--alt-preset insane</code>, etc.)<br />
<br />

<div>'''Lossless compression''' is a compression methodology in which the result of the compression can be restored faithfully, i.e. bit-by-bit identical with the uncompressed data.<br />
<br />
In a nutshell, it is somewhat like compressing a Waveform file with ZIP or RAR.<br />
<br />
The difference between 'mere' ZIP/RAR is that lossless compression algorithms are especially tuned and designed for the characteristics of Waveform data, thus achieving compression far greater than can be achieved by generic compression utilities.<br />
<br />
As lossless compression preserves all information of the original Waveform file, audio compressed with lossless compression will unavoidably be larger than audio compressed with [[lossy]] compression. However, this disadvantage is more than offset by lossless' ability to be [[transcoding|transcoded]] to other lossless format <u>without</u> any quality degradation.<br />
<br />
<br />
==Popular lossless formats==<br />
* [[Apple Lossless]] ([[ALAC]])<br />
<br />

<br />
* [[Lossless Audio]] ([[LA]])<br />

<br />
* [[WavPack]]<br />
<br />
* [[WMA | WMA lossless]]<br />
<br />
<br />
==Oddball Formats==<br />
There are several old lossless formats that aren't really deserving of having an article all for themselves. Reasons are: lack of widespread support, lack of features, bad efficiency and, most importantly, it seems noone is really interested in them.<br />
<br />
Most of those would have disappeared by now, but they are being preserved for posterity at [[User:Rjamorim|rjamorim]]'s [http://www.rjamorim.com/rrw/ ReallyRareWares]<br />

Note that currently '''no single format can be considered best for all applications'''. Rather, the best format depends on the ''intended use'', as well as a number of other factors (such as licensing and file structure). For example, Shorten and FLAC are widely used for sharing live music because of their cross-platform support and speed. Monkey's Audio is popular among Windows users for its superior compression ratio.<br />

'''Ogg''' is a multimedia container format, and the native file and stream format developed by [http://www.xiph.org/ Xiph.Org], for their multimedia codecs. It an open format free for anyone to use. It is usually used to store [[Vorbis]] audio (or, less commonly, [[Theora]] video), and because of this, "Ogg" has been used incorrectly to refer to Vorbis.<br />
<br />
For more details, see [http://www.xiph.org/ogg/ Xiph's explanation of the Ogg container].<br />
<br />
See also [http://en.wikipedia.org/wiki/Ogg Ogg entry in Wikipedia].<br />
<br />
<br />
==Features==<br />
<br />
* encapsulation and interleave of multiple data streams,<br />
* packet framing<br />
* error detection<br />
* seeking<br />
<br />
All in a small, bounded percentage bitrate overhead.<br />
<br />
Ogg format specification is now published within the IETF in the following [[RFC]]s:<br />
<br />
* RFC 3533 The Ogg Encapsulation Format Version 0<br />
* RFC 3534 The application/ogg Media Type<br />

'''Vorbis''' (commonly used inside the [[Ogg]] container) is a fully open, non-proprietary, patent-free (subject to [http://www.hydrogenaudio.org/forums/index.php?showtopic=13531 speculation]), and royalty-free, general-purpose compressed audio format for mid to high quality (8khz-48.0kHz, 16+ bit, [[multichannel]]) audio and music at fixed and variable bitrates from 16 to >256 kbps/channel. This places vorbis in the same competitive class as audio representations such as MPEG-4 ([[AAC]]), and similar to, but higher performance than [[MP3]], TwinVQ ([[VQF]]), [[WMA]] and [[PAC]]. Vorbis is the first of a planned family of Ogg multimedia coding formats being developed as part of Xiph.org's ogg multimedia project.<br />
<br />
Informal listening test suggests Vorbis to be comparable to MPEG-4 [[AAC]] at most bitrates and [[MPC]] at 128 kbps. Transparency is generally reached at about 150-170 kbps (-q 5) (with some exceptions). The encoder is reasonably young and unoptimized, so further improvements can always be expected.<br />
<br />
Unfortunately, Xiph.org has failed to improve Vorbis at a steady rate since its initial 1.0 release in July 2002 (due to other developement projects and time constraints). Since then development has been led by other coders such as [http://sjeng.org/vorbisgt3.html Garf] and [http://www.geocities.jp/aoyoume/aotuv/ Aoyumi]. Aoyumi's '''[[aoTuV]]''' series of encoders was incorporated into the September 2004 release of 1.1, which brought about the first quality improvements across the board for 2 years. Currently Aoyumi is working on aoTuV Beta 5 and future releases. The latest version is aoTuV Release 1, which is the re-branded Beta 4.51 (released in December 2005). Unfortunately, the improvements of aoTuV Release 1 has not been incorporated yet into the 'official' Vorbis line.<br />
<br />
Vorbis has had success with many recent video game titles employing Vorbis as opposed to MP3 (with Epic Games' Unreal Tournament 2003 and Unreal Tournament 2004, the PC port of Microsoft's Halo and Uru being notable examples). Ogg Vorbis is also an official part of the [http://www.openal.org/extensions.html OpenAL] API extension library, used in many popular [http://www.openal.org/titles.html computer games]. On April 10, 2006, [http://www.radgametools.com/ RAD Game Tools] integrated Ogg Vorbis support to their Miles Sound System (MSS), which has been used in over 3,200 games worldwide. This ensures that future games utilizing MSS will have the capability to play Ogg Vorbis files. Check out [http://wiki.xiph.org/index.php/Games_that_use_Vorbis xiph wiki] for a full list of games confirmed to use Ogg Vorbis. <br />
<br />
'''Before encoding files using Ogg Vorbis, check out the [[Recommended Ogg Vorbis|Recommended Ogg Vorbis article]] to determine what encoder to use and what settings are recommended by Hydrogenaudio.'''<br />
<br />
==Pros==<br />
* Ogg Vorbis specification is in the public domain; it is free for commercial or noncommercial use, under both (LGPL and BSD licenes)<br />
* Easy to use high-level API (Application Programming Interface)<br />
* Good all-round performance (>48 kbps - a leading codec at [http://www.rjamorim.com/test/multiformat128/results.html 128 kbps])<br />
* Well written [http://www.xiph.org/ogg/vorbis/docs.html specs]<br />
* Supported by most portable [[Ogg Vorbis#Supporting Digital Audio Players|DAPs]]<br />
* Suitable for internet-streaming (via [http://www.icecast.org/ Icecast] and other methods)<br />
* Fully [[gapless]] playback<br />
* High potential for further tuning<br />
* Structured to allow the design for a hybrid filterbank<br />
<br />
==Cons==<br />
* Limited official development (third-party developement is always encouraged)<br />
* Current implementations are more computationally intensive to decode than MP3<br />
* Multichannel input mappings for 5.1, Ambisonic-B, and other configs have no channel coupling and aren't tuned (expect sub-optimal results until code is improved)<br />
<br />
==Technical Information==<br />
* Multiple block sizes for window switching including overlap (powers of two only) ''(128/1024, 256/2048, 512/4096)''<br />
* Customly designed [[window function]] is applied similiar to the sine window. it has (good sidelobe rejection) <br />
:<font size="8pt"><math>w_k = \sin{(\frac{\pi}{2} \cdot sin^2[(\pi\div2n \cdot (k+0.5))]}</math></font><br />
* Psychoacoustics masking is exploited via an ([[ATH]] model)<br />
* Masking curves are computed from an ''emperically'' adjusted set of [http://www.zainea.com/masking2.htm Ehmer Curves]<br />
* Modified Discrete Cosine Transform ([[MDCT]]) is used for noise analysis<br />
* Fast Fourier Transform ([[FFT]]) is used for tonal analysis<br />
* Global masking curve is a mixture between calculated FFT+MDCT curves and ATH curves overlayed<br />
* Floor 1 or the noise-floor (envelope) is calculated using the global masking curve & piecewise linear approximation divided by spectrum to generate the residue (fine detail). The Levinson-Durbin [http://www.data-compression.com/speech.html#ana LPC model] in Floor 0 is no longer used, however the code still exists<br />
* [[Noise normalization]] is applied to compensate for energy lost in certain frequency bands due to quantization (rounding). <br />
* The channels are [[channel coupling|coupled]] ''strictly'' by residue using ([http://us.xiph.org/ogg/vorbis/doc/stereo.html point/phase stereo] and lossless)<br />
* Multistage [[Vector quantization]] is used for coding the noise-floor and residue backend using ''trained'' codebooks.<br />
* [[Huffman coding]] is used to minimize vector codeword redundancy<br />

<div>2006-04-06 22h43 Norz: Hi! Best wishes to you & Vorbis! :)<br />
<br />
== Alright then ==<br />
<br />
So, my templates that the community has mostly used and help give an overview of articles are "stupid". Okay, fair game. The articles [[Ableton Live]], [[Ardour]]... are stupid. Stop making them.<br />
<br />
Polite, isn't it? {{User:Elliottmobile/sig2}} 03:22, 2 October 2006 (CDT)<br />
<br />
They are "stupid" in a sense that HA does no co-exist on the large scale that wikipedia does. Some of your templates are useful, but we have no use for your templates and the fact that you wish to enforce them on others. This is the only way you are making contributions to the wiki. Quite frankly it's annoying our wiki editors, my self included. Maybe you care to actually write some pages? yes? When Beto contributed the Software Infobox to the community he did it out of necessity. HA does not run things in the same manner the way wikipedia does. It's based upon the best interest of the community at hand. Are References necessary for pages? yes? can we expand the wiki based upon the particular interest of the community as a whole? yes? we can. Do we need to strictly enforce rules on a grand scale? no. There are only four to five dedicated user that make contributions to our wiki anyhow do the due to the time needed and the technical skills required to translate complicated matters into plain english. --[[User:HotshotGG|HotshotGG]] 16:19, 2 October 2006 (CDT)<br />
<br />
[http://wiki.hydrogenaudio.org/index.php?title=Special%3AContributions&offset=0&limit=50&target=Elliottmobile&namespace=0 A list of all my article-only contributions.] All I contribute is templates, now? {{User:Elliottmobile/sig2}} 14:59, 2 October 2006 (CDT)<br />
<br />
You are just moving stuff around and maintaining things from what I can tell by those edits. You are just contributing to the templates/maintenence nothing else. If you are only job is police the wiki like, such expect to recieve more critisism. You single handledly violated the wiki policy anyway, by interjecting personal opinion into a page that was unecessary. Save your opionions for your own personal user page and respect other people space. Once you have done so I will be a little more polite. I think a few others would agree. --[[User:HotshotGG|HotshotGG]] 17:25 2 October 2006 (CDT)<br />

#That was before policy even existed here.<br />

Canar for example. It's very simple stay off my case and don't violate your own policies. --[[User:HotshotGG|HotshotGG]] 16:26, 4 October 2006 (CDT)<br />

Apart from you, there's Canar.

<br />
'''Vorbis''' (commonly used inside the [[Ogg]] container) is a fully open, non-proprietary, patent-free (subject to [http://www.hydrogenaudio.org/forums/index.php?showtopic=13531 speculation]), and royalty-free, general-purpose compressed audio format for mid to high quality (8khz-48.0kHz, 16+ bit, [[multichannel]]) audio and music at fixed and variable bitrates from 16 to >256 kbps/channel. This places vorbis in the same competitive class as audio representations such as MPEG-4 ([[AAC]]), and similar to, but higher performance than [[MP3]], TwinVQ ([[VQF]]), [[WMA]] and [[PAC]]. Vorbis is the first of a planned family of Ogg multimedia coding formats being developed as part of Xiph.org's ogg multimedia project.<br />
<br />
Informal listening test suggests Vorbis to be comparable to MPEG-4 [[AAC]] at most bitrates and [[MPC]] at 128 kbps. Transparency is generally reached at about 150-170 kbps (-q 5) (with some exceptions). The encoder is reasonably young and unoptimized, so further improvements can always be expected.<br />
<br />
Unfortunately, Xiph.org has failed to improve Vorbis at a steady rate since its initial 1.0 release in July 2002 (due to other developement projects and time constraints). Since then development has been led by other coders such as [http://sjeng.org/vorbisgt3.html Garf] and [http://www.geocities.jp/aoyoume/aotuv/ Aoyumi]. Aoyumi's '''[[aoTuV]]''' series of encoders was incorporated into the September 2004 release of 1.1, which brought about the first quality improvements across the board for 2 years. Currently Aoyumi is working on aoTuV Beta 5 and future releases. The latest version is aoTuV Release 1, which is the re-branded Beta 4.51 (released in December 2005). Unfortunately, the improvements of aoTuV Release 1 has not been incorporated yet into the 'official' Vorbis line.<br />
<br />
Vorbis has had success with many recent video game titles employing Vorbis as opposed to MP3 (with Epic Games' Unreal Tournament 2003 and Unreal Tournament 2004, the PC port of Microsoft's Halo and Uru being notable examples). Ogg Vorbis is also an official part of the [http://www.openal.org/extensions.html OpenAL] API extension library, used in many popular [http://www.openal.org/titles.html computer games]. On April 10, 2006, [http://www.radgametools.com/ RAD Game Tools] integrated Ogg Vorbis support to their Miles Sound System (MSS), which has been used in over 3,200 games worldwide. This ensures that future games utilizing MSS will have the capability to play Ogg Vorbis files. Check out [http://wiki.xiph.org/index.php/Games_that_use_Vorbis xiph wiki] for a full list of games confirmed to use Ogg Vorbis. <br />
<br />
Before encoding files using Ogg Vorbis, check out the [[Recommended Ogg Vorbis]] to determine what encoder to use and what settings are recommended by Hydrogenaudio. <br />
<br />
==Pros==<br />
* Ogg Vorbis specification is in the public domain; it is free for commercial or noncommercial use, under both (LGPL and BSD licenes)<br />
* Easy to use high-level API (Application Programming Interface)<br />
* Good all-round performance (>48 kbps - a leading codec at [http://www.rjamorim.com/test/multiformat128/results.html 128 kbps])<br />
* Well written [http://www.xiph.org/ogg/vorbis/docs.html specs]<br />
* Supported by most portable [[Ogg Vorbis#Supporting Digital Audio Players|DAPs]]<br />
* Suitable for internet-streaming (via [http://www.icecast.org/ Icecast] and other methods)<br />
* Fully [[gapless]] playback<br />
* High potential for further tuning<br />
* Structured to allow the design for a hybrid filterbank<br />
<br />
==Cons==<br />
* Limited official development (third-party developement is always encouraged)<br />
* Current implementations are more computationally intensive to decode than MP3<br />
* Multichannel input mappings for 5.1, Ambisonic-B, and other configs have no channel coupling and aren't tuned (expect sub-optimal results until code is improved)<br />
<br />
==Technical Information==<br />
* Multiple block sizes for window switching including overlap (powers of two only) ''(128/1024, 256/2048, 512/4096)''<br />
* Customly designed [[window function]] is applied similiar to the sine window. it has (good sidelobe rejection) <br />
:<font size="8pt"><math>w_k = \sin{(\frac{\pi}{2} \cdot sin^2[(\pi\div2n \cdot (k+0.5))]}</math></font><br />
* Psychoacoustics masking is exploited via an ([[ATH]] model)<br />
* Masking curves are computed from an ''emperically'' adjusted set of [http://www.zainea.com/masking2.htm Ehmer Curves]<br />
* Modified Discrete Cosine Transform ([[MDCT]]) is used for noise analysis<br />
* Fast Fourier Transform ([[FFT]]) is used for tonal analysis<br />
* Global masking curve is a mixture between calculated FFT+MDCT curves and ATH curves overlayed<br />
* Floor 1 or the noise-floor (envelope) is calculated using the global masking curve & piecewise linear approximation divided by spectrum to generate the residue (fine detail). The Levinson-Durbin [http://www.data-compression.com/speech.html#ana LPC model] in Floor 0 is no longer used, however the code still exists<br />
* [[Noise normalization]] is applied to compensate for energy lost in certain frequency bands due to quantization (rounding). <br />
* The channels are [[channel coupling|coupled]] ''strictly'' by residue using ([http://us.xiph.org/ogg/vorbis/doc/stereo.html point/phase stereo] and lossless)<br />
* Multistage [[Vector quantization]] is used for coding the noise-floor and residue backend using ''trained'' codebooks.<br />
* [[Huffman coding]] is used to minimize vector codeword redundancy<br />

FLAC is similar to [[MP3]], but [[lossless]], meaning that audio is compressed in FLAC without any loss in quality. This is similar to how Zip works, except with FLAC you will get much better compression because it is designed specifically for audio, and you can play back compressed FLAC files in your favorite player (or your car or home stereo, see supported devices) just like you would an MP3 file.<br />
<br />
FLAC stands for Free Lossless Audio Codec. "Free" means "Free" - that the specification of the stream format is in the public domain. It also means that the sources for libFLAC and libFLAC++ are available under the BSD (Berkeley Software Distribution) licence.<br />
<br />
FLAC compiles on many platforms. <br />
<br />
Some claim FLAC is the most widely used lossless compression format on UNIX systems (though it seems more likely that shn retains that honor on all OS platforms).<br />
<br />
FLAC files can be placed inside an Ogg container using libOggFLAC and libOggFLAC++. <br />
<br />
==Pros==<br />
* Portable to many systems<br />
* Source open and freely licenced<br />
* Hardware support (PhatBox, Kenwood MusicKeg, Rio Karma, etc. See below)<br />
* Streaming support<br />
* Extremely fast decoding<br />
* Supports multichannel and high resolution streams<br />
* Supports [[ReplayGain]]<br />
* Supports cue-sheet (with some limitations)<br />
* Gaining wide use as successor to [[Shorten]]<br />
<br />
==Cons==<br />
* Compresses less efficiently than other popular modern compressors ([[Monkey's Audio]], [[OptimFROG]])<br />
* Higher compression modes slow, for little gain over the default setting.<br />

=Frequently Asked Questions=<br />
<br />
''Question:'' Does the compression level affect decompression speed?<br />
<br />
''Short Answer'': No.<br />
<br />
''Long Answer'': In truth, the compression level does affect the decompression speed, but the difference between the various compress levels can barely be measured and is too small to be noticed, even on low-end machines.<br />
<br />
<br />
''Question:'' What is the best compression level for encoding my music?<br />
<br />
''Short Answer'': The default setting, 5.<br />
<br />
''Long Answer'': Encoding at the default setting will give the best balance between compression and encoding speed. Encoding at 8 can more than quadruple the encoding time, while having an insignificant effect on compression.<br />

'''Vorbis''' (commonly used inside the [[OGG]] container) is a fully open, non-proprietary, patent-free (subject to [http://www.hydrogenaudio.org/forums/index.php?showtopic=13531 speculation]), and royalty-free, general-purpose compressed audio format for mid to high quality (8khz-48.0kHz, 16+ bit, [[multichannel]]) audio and music at fixed and variable bitrates from 16 to >256 kbps/channel. This places vorbis in the same competitive class as audio representations such as MPEG-4 ([[AAC]]), and similar to, but higher performance than [[MP3]], TwinVQ ([[VQF]]), [[WMA]] and [[PAC]]. Vorbis is the first of a planned family of Ogg multimedia coding formats being developed as part of Xiph.org's ogg multimedia project.<br />
<br />
Informal listening test suggests Vorbis to be comparable to MPEG-4 [[AAC]] at most bitrates and [[MPC]] at 128 kbps. Transparency is generally reached at about 150-170 kbps (-q 5) (with some exceptions). The encoder is reasonably young and unoptimized, so further improvements can always be expected.<br />
<br />
Unfortunately, Xiph.org has failed to improve Vorbis at a steady rate since its initial 1.0 release in July 2002 (due to other developement projects and time constraints). Since then development has been led by other coders such as [http://sjeng.org/vorbisgt3.html Garf] and [http://www.geocities.jp/aoyoume/aotuv/ Aoyumi]. Aoyumi's '''[[aoTuV]]''' series of encoders was incorporated into the September 2004 release of 1.1, which brought about the first quality improvements across the board for 2 years. Currently Aoyumi is working on aoTuV Beta 5 and future releases. The latest version is aoTuV Release 1, which is the re-branded Beta 4.51 (released in December 2005). Unfortunately, the improvements of aoTuV Release 1 has not been incorporated yet into the 'official' Vorbis line.<br />
<br />
Vorbis has had success with many recent video game titles employing Vorbis as opposed to MP3 (with Epic Games' Unreal Tournament 2003 and Unreal Tournament 2004, the PC port of Microsoft's Halo and Uru being notable examples). Ogg Vorbis is also an official part of the [http://www.openal.org/extensions.html OpenAL] API extension library, used in many popular [http://www.openal.org/titles.html computer games]. On April 10, 2006, [http://www.radgametools.com/ RAD Game Tools] integrated Ogg Vorbis support to their Miles Sound System (MSS), which has been used in over 3,200 games worldwide. This ensures that future games utilizing MSS will have the capability to play Ogg Vorbis files. Check out [http://wiki.xiph.org/index.php/Games_that_use_Vorbis xiph wiki] for a full list of games confirmed to use Ogg Vorbis. <br />
<br />
Before encoding files using Ogg Vorbis, check out the [[Recommended Ogg Vorbis]] to determine what encoder to use and what settings are recommended by Hydrogenaudio. <br />
<br />
==Pros==<br />
* Ogg Vorbis specification is in the public domain; it is free for commercial or noncommercial use, under both (LGPL and BSD licenes)<br />
* Easy to use high-level API (Application Programming Interface)<br />
* Good all-round performance (>48 kbps - a leading codec at [http://www.rjamorim.com/test/multiformat128/results.html 128 kbps])<br />
* Well written [http://www.xiph.org/ogg/vorbis/docs.html specs]<br />
* Supported by most portable [[Ogg Vorbis#Supporting Digital Audio Players|DAPs]]<br />
* Suitable for internet-streaming (via [http://www.icecast.org/ Icecast] and other methods)<br />
* Fully [[gapless]] playback<br />
* High potential for further tuning<br />
* Structured to allow the design for a hybrid filterbank<br />
<br />
==Cons==<br />
* Limited official development (third-party developement is always encouraged)<br />
* Current implementations are more computationally intensive to decode than MP3<br />
* Multichannel input mappings for 5.1, Ambisonic-B, and other configs have no channel coupling and aren't tuned (expect sub-optimal results until code is improved)<br />
<br />
<br />
==Technical Information==<br />
* Multiple block sizes for window switching including overlap (powers of two only) ''(128/1024, 256/2048, 512/4096)''<br />
* Customly designed [[window function]] is applied similiar to the sine window. it has (good sidelobe rejection) <br />
:<font size="8pt"><math>w_k = \sin{(\frac{\pi}{2} \cdot sin^2[(\pi\div2n \cdot (k+0.5))]}</math></font><br />
* Psychoacoustics masking is exploited via an ([[ATH]] model)<br />
* Masking curves are computed from an ''emperically'' adjusted set of [http://www.zainea.com/masking2.htm Ehmer Curves]<br />
* Modified Discrete Cosine Transform ([[MDCT]]) is used for noise analysis<br />
* Fast Fourier Transform ([[FFT]]) is used for tonal analysis<br />
* Global masking curve is a mixture between calculated FFT+MDCT curves and ATH curves overlayed<br />
* Floor 1 or the noise-floor (envelope) is calculated using the global masking curve & piecewise linear approximation divided by spectrum to generate the residue (fine detail). The Levinson-Durbin [http://www.data-compression.com/speech.html#ana LPC model] in Floor 0 is no longer used, however the code still exists<br />
* [[Noise normalization]] is applied to compensate for energy lost in certain frequency bands due to quantization (rounding). <br />
* The channels are [[channel coupling|coupled]] ''strictly'' by residue using ([http://us.xiph.org/ogg/vorbis/doc/stereo.html point/phase stereo] and lossless)<br />
* Multistage [[Vector quantization]] is used for coding the noise-floor and residue backend using ''trained'' codebooks.<br />
* [[Huffman coding]] is used to minimize vector codeword redundancy<br />

'''Vorbis''' (commonly used inside the [[OGG]] container) is a fully open, non-proprietary, patent-free (subject to [http://www.hydrogenaudio.org/forums/index.php?showtopic=13531 speculation]), and royalty-free, general-purpose compressed audio format for mid to high quality (8khz-48.0kHz, 16+ bit, [[multichannel]]) audio and music at fixed and variable bitrates from 16 to >256 kbps/channel. This places vorbis in the same competitive class as audio representations such as MPEG-4 ([[AAC]]), and similar to, but higher performance than [[MP3]], TwinVQ ([[VQF]]), [[WMA]] and [[PAC]]. Vorbis is the first of a planned family of Ogg multimedia coding formats being developed as part of Xiph.org's ogg multimedia project.<br />
<br />
Informal listening test suggests Vorbis to be comparable to MPEG-4 [[AAC]] at most bitrates and [[MPC]] at 128 kbps. Transparency is generally reached at about 150-170 kbps (-q 5) (with some exceptions). The encoder is reasonably young and unoptimized, so further improvements can always be expected.<br />
<br />
Unfortunately, Xiph.org has failed to improve Vorbis at a steady rate since its initial 1.0 release in July 2002 (due to other developement projects and time constraints). Since then development has been led by other coders such as [http://sjeng.org/vorbisgt3.html Garf] and [http://www.geocities.jp/aoyoume/aotuv/ Aoyumi]. Aoyumi's '''[[aoTuV]]''' series of encoders was incorporated into the September 2004 release of 1.1, which brought about the first quality improvements across the board for 2 years. Currently Aoyumi is working on aoTuV Beta 5 and future releases. The latest version is aoTuV Release 1, which is the re-branded Beta 4.51 (released in December 2005). Unfortunately, the improvements of aoTuV Release 1 has not been incorporated yet into the 'official' Vorbis line.<br />
<br />
Vorbis has had success with many recent video game titles employing Vorbis as opposed to MP3 (with Epic Games' Unreal Tournament 2003 and Unreal Tournament 2004, the PC port of Microsoft's Halo and Uru being notable examples). Ogg Vorbis is also an official part of the [http://www.openal.org/extensions.html OpenAL] API extension library, used in many popular [http://www.openal.org/titles.html computer games]. On April 10, 2006, [http://www.radgametools.com/ RAD Game Tools] integrated Ogg Vorbis support to their Miles Sound System (MSS), which has been used in over 3,200 games worldwide. This ensures that future games utilizing MSS will have the capability to play Ogg Vorbis files. Check out [http://wiki.xiph.org/index.php/Games_that_use_Vorbis xiph wiki] for a full list of games confirmed to use Ogg Vorbis. <br />
<br />
Before encoding files using Ogg Vorbis, check out the [[Recommended Ogg Vorbis]] to determine what encoder to use and what settings are recommended by Hydrogenaudio. <br />
<br />
==Pros==<br />
* Ogg Vorbis specification is in the public domain; it is free for commercial or noncommercial use, under both (LGPL and BSD licenes)<br />
* Easy to use high-level API (Application Programming Interface)<br />
* Good all-round performance (>48 kbps - a leading codec at [http://www.rjamorim.com/test/multiformat128/results.html 128 kbps])<br />
* Well written [http://www.xiph.org/ogg/vorbis/docs.html specs]<br />
* Supported by most portable [[Ogg Vorbis#Supporting Digital Audio Players|DAPs]]<br />
* Suitable for internet-streaming (via [http://www.icecast.org/ Icecast] and other methods)<br />
* Fully [[gapless]] playback<br />
* High potential for further tuning<br />
* Structured to allow the design for a hybrid filterbank<br />
<br />
==Cons==<br />
* Limited official development (third-party developement is always encouraged)<br />
* Current implementations are more computationally intensive to decode than MP3<br />
* Multichannel input mappings for 5.1, Ambisonic-B, and other configs have no channel coupling and aren't tuned (expect sub-optimal results until code is improved)<br />
<br />
<br />
==Technical Information==<br />
* Multiple block sizes for window switching including overlap (powers of two only) ''(128/1024, 256/2048, 512/4096)''<br />
* Customly designed [[window function]] is applied similiar to the sine window. it has (good sidelobe rejection) <br />
:<font size="8pt"><math>w_k = \sin{(\frac{\pi}{2} \cdot sin^2[(\pi\div2n \cdot (k+0.5))]}</math></font><br />

==Recommended Encoder==<br />
<br />
'''Despite''' what you said in your comment, HotshotGG, remember that this is '''Hydrogenaudio''' Knowledgebase, so the recommended encoder should be what the HA folks recommend, i.e. aoTuV R1. ''Even though'' aoTuV R1 is not part of the mainline.<br />
<br />
I cannot recommend Xiph 1.1.2 with a clear conscience as deep within I *know* that 1.1.2 is inferior to R1.<br />

<br />
==Legal Brouhaha==<br />
I don't see any purpose rehashing this whole legal thing again. If peoeple are interested in the discussion they should just read the thread. HotshotGG 17 June 2005 (EST)<br />
<br />
: Well, I lifted that text directly from Wikipedia, and I thought it to be very interesting, as it clarifies the situation while doing caveats that everything could be just FUD from the competitors. rjamorim 00:55, 19 Jun 2005 (CDT)<br />
<br />
:: Yeah that's true, I understand were you are coming from. Wikipedia just has it their reguarding the liscense and the whole issues is up in the air. 00:12, HotshotGG 20 Jun 2005 (EST)<br />
<br />
::: Also, I believe just a small paragraph summarizing the whole bruhaha is much better that telling the article readers "read and understand these 15 pages of messily organized and barely chronological forum posts". But that's just me. :B rjamorim 10:58, 20 Jun 2005 (CDT)<br />
<br />
:::: I am overdueing it a little with this page. I just want to be as specific as possible though for anyone who visits it ;-d. Maybe we should add the xiph logo to as well? hmm, also technical Vorbis doesn't use a straight MDCT it uses a FFT to do some tone masking ;-O (that's really irrlevant though). The specs won't tell the user too much about encoding, therefore I'm trying to fill in some technical gaps here. HotshotGG 2:30, 23 June 2005 (EST)<br />
<br />
==Ogg Vorbis or Ogg + Vorbis==<br />
<br />
As Ogg is the container format and Vorbis the codec, wouldn't it be more accurate to have a [[Vorbis]] and an [[Ogg]] page, along with this one being a redirection or a placeholder page that contains links to the two formers? [[User:Nowhere man|Nowhere man]] 13:34, 21 Sep 2005 (CDT)<br />
<br />
: That's not a bad idea. I don't the situation is as bad wikipedia though. Most people who visit this wiki know Vorbis is Vorbis. [[User:HotshotGG|HotshotGG]] 20:29, 26 May 2006 (CDT)<br />

Where is the download link for VorbisGain/POSIX? Rarewares I think only host the Win32 binaries. --[[User:Pepoluan|pepoluan]] 13:19, 23 May 2006 (CDT)<br />
<br />
: It does exist I think Garf has a POSIX compile of VorbisGain on his website. Roberto is very stingy when it comes to hosting POSIX binaries on Rarewares. If I had the source I could try and compile it myself, I don't have access to Linux right now, but I will get around to it eventually. It would be great it we could find someone to create an OS/X compile for MAC too. --[[User:HotshotGG|HotshotGG]] 20:26, 26 May 2006 (CDT)<br />

=Introduction= <br />
'''Ogg Vorbis''' ([http://www.vorbis.com www.vorbis.com]) is a fully open, non-proprietary, patent-free (subject to [http://www.hydrogenaudio.org/forums/index.php?showtopic=13531 speculation]), and royalty-free, general-purpose compressed audio format for mid to high quality (8khz-48.0kHz, 16+ bit, [[multichannel]]) audio and music at fixed and variable bitrates from 16 to >256 kbps/channel. This places vorbis in the same competitive class as audio representations such as MPEG-4 ([[AAC]]), and similar to, but higher performance than [[MP3]], TwinVQ ([[VQF]]), [[WMA]] and [[PAC]]. Vorbis is the first of a planned family of Ogg multimedia coding formats being developed as part of Xiph.org's ogg multimedia project.<br />
<br />
Informal listening test suggests Vorbis to be comparable to MPEG-4 [[AAC]] at most bitrates and [[MPC]] at 128 kbps. Transparency is generally reached at about 150-170 kbps (-q 5) (with some exceptions). The encoder is reasonably young and unoptimized, so further improvements can always be expected.<br />
<br />
Unfortunately, Xiph.org has failed to improve Vorbis at a steady rate since its initial 1.0 release in July 2002 (due to other developement projects and time constraints). Since then development has been led by other coders such as [http://sjeng.org/vorbisgt3.html Garf] and [http://www.geocities.jp/aoyoume/aotuv/ Aoyumi]. Aoyumi's '''[[aoTuV]]''' series of encoders was incorporated into the September 2004 release of 1.1, which brought about the first quality improvements across the board for 2 years. Currently Aoyumi is working on aoTuV Beta 5 and future releases. The latest version is aoTuV Release 1, which is the re-branded Beta 4.51 (released in December 2005). Unfortunately, the improvements of aoTuV Release 1 has not been incorporated yet into the 'official' Vorbis line.<br />
<br />
Vorbis has had success with many recent video game titles employing Vorbis as opposed to MP3 (with Epic Games' Unreal Tournament 2003 and Unreal Tournament 2004, the PC port of Microsoft's Halo and Uru being notable examples). Ogg Vorbis is also an official part of the [http://www.openal.org/extensions.html OpenAL] API extension library, used in many popular [http://www.openal.org/titles.html computer games]. On April 10, 2006, [http://www.radgametools.com/ RAD Game Tools] integrated Ogg Vorbis support to their Miles Sound System (MSS), which has been used in over 3,200 games worldwide. This ensures that future games utilizing MSS will have the capability to play Ogg Vorbis files. Check out [http://wiki.xiph.org/index.php/Games_that_use_Vorbis xiph wiki] for a full list of games confirmed to use Ogg Vorbis. <br />
<br />
Before encoding files using Ogg Vorbis, check out the [[Recommended Ogg Vorbis]] to determine what encoder to use and what settings are recommended by Hydrogenaudio. <br />
<br />
==Pros==<br />
* Ogg Vorbis specification is in the public domain; it is free for commercial or noncommercial use, under both (LGPL and BSD licenes)<br />
* Easy to use high-level API (Application Programming Interface)<br />
* Good all-round performance (>48 kbps - a leading codec at [http://www.rjamorim.com/test/multiformat128/results.html 128 kbps])<br />
* Well written [http://www.xiph.org/ogg/vorbis/docs.html specs]<br />
* Supported by most portable [[Ogg Vorbis#Supporting Digital Audio Players|DAPs]]<br />
* Suitable for internet-streaming (via [http://www.icecast.org/ Icecast] and other methods)<br />
* Fully [[gapless]] playback<br />
* High potential for further tuning<br />
* Structured to allow the design for a hybrid filterbank<br />
<br />
==Cons==<br />
* Limited official development (third-party developement is always encouraged)<br />
* Current implementations are more computationally intensive to decode than MP3<br />
* Multichannel input mappings for 5.1, Ambisonic-B, and other configs have no channel coupling and aren't tuned (expect sub-optimal results until code is improved)<br />
<br />
<br />
=Technical Information=<br />
* Multiple block sizes for window switching including overlap (powers of two only) ''(128/1024, 256/2048, 512/4096)''<br />
* Customly designed [[window function]] is applied similiar to the sine window. it has (good sidelobe rejection) <br />
:<font size="8pt"><math>w_k = \sin{(\frac{\pi}{2} \cdot sin^2[(\pi\div2n \cdot (k+0.5))]}</math></font><br />
* Psychoacoustics masking is exploited via an ([[ATH]] model)<br />
* Masking curves are computed from an ''emperically'' adjusted set of [http://www.zainea.com/masking2.htm Ehmer Curves]<br />
* Modified Discrete Cosine Transform ([[MDCT]]) is used for noise analysis<br />
* Fast Fourier Transform ([[FFT]]) is used for tonal analysis<br />
* Global masking curve is a mixture between calculated FFT+MDCT curves and ATH curves overlayed<br />
* Floor 1 or the noise-floor (envelope) is calculated using the global masking curve & piecewise linear approximation divided by spectrum to generate the residue (fine detail). The Levinson-Durbin [http://www.data-compression.com/speech.html#ana LPC model] in Floor 0 is no longer used, however the code still exists<br />
* [[Noise normalization]] is applied to compensate for energy lost in certain frequency bands due to quantization (rounding). <br />
* The channels are [[channel coupling|coupled]] ''strictly'' by residue using ([http://us.xiph.org/ogg/vorbis/doc/stereo.html point/phase stereo] and lossless)<br />
* Multistage [[Vector quantization]] is used for coding the noise-floor and residue backend using ''trained'' codebooks.<br />
* [[Huffman coding]] is used to minimize vector codeword redundancy<br />

FLAC is similar to [[MP3]], but [[lossless]], meaning that audio is compressed in FLAC without any loss in quality. This is similar to how Zip works, except with FLAC you will get much better compression because it is designed specifically for audio, and you can play back compressed FLAC files in your favorite player (or your car or home stereo, see supported devices) just like you would an MP3 file.<br />
<br />
FLAC stands for Free Lossless Audio Codec. "Free" means "Free" - that the specification of the stream format is in the public domain. It also means that the sources for libFLAC and libFLAC++ are available under the BSD (Berkeley Software Distribution) licence.<br />
<br />
FLAC compiles on many platforms. <br />
<br />
Some claim FLAC is the most widely used lossless compression format on UNIX systems (though it seems more likely that shn retains that honor on all OS platforms).<br />
<br />
FLAC files can be placed inside an Ogg container using libOggFLAC and libOggFLAC++. <br />
<br />
==Pros==<br />
* Portable to many systems<br />
* Source open and freely licenced<br />
* Hardware support (PhatBox, Kenwood MusicKeg, Rio Karma, etc. See below)<br />
* Streaming support<br />
* Extremely fast decoding<br />
* Supports multichannel and high resolution streams<br />
* Supports [[ReplayGain]]<br />
* Supports cue-sheet (with some limitations)<br />
* Gaining wide use as successor to [[Shorten]]<br />
<br />
==Cons==<br />
* Compresses less efficiently than other popular modern compressors ([[Monkey's Audio]], [[OptimFROG]])<br />
* Higher compression modes slow, for little gain over the default setting.<br />

=Frequently Asked Questions=<br />
<br />
''Question:'' Does the compression level affect decompression speed?<br />
<br />
''Short Answer'': No.<br />
<br />
''Long Answer'': In truth, the compression level does affect the decompression speed, but the difference between the various compress levels can barely be measured and is too small to be noticed, even on low-end machines.<br />
<br />
<br />
''Question:'' What is the best compression level for encoding my music?<br />
<br />
''Short Answer'': The default setting, 5.<br />
<br />
''Long Answer'': Encoding at the default setting will give the best balance between compression and encoding speed. Encoding at 8 can more than quadruple the encoding time, while having an insignificant effect on compression.<br />

=Introduction= <br />
'''Ogg Vorbis''' ([http://www.vorbis.com www.vorbis.com]) is a fully open, non-proprietary, patent-free (subject to [http://www.hydrogenaudio.org/forums/index.php?showtopic=13531 speculation]), and royalty-free, general-purpose compressed audio format for mid to high quality (8khz-48.0kHz, 16+ bit, [[multichannel]]) audio and music at fixed and variable bitrates from 16 to >256 kbps/channel. This places vorbis in the same competitive class as audio representations such as MPEG-4 ([[AAC]]), and similar to, but higher performance than [[MP3]], TwinVQ ([[VQF]]), [[WMA]] and [[PAC]]. Vorbis is the first of a planned family of Ogg multimedia coding formats being developed as part of Xiph.org's ogg multimedia project.<br />
<br />
Informal listening test suggests Vorbis to be comparable to MPEG-4 [[AAC]] at most bitrates and [[MPC]] at 128 kbps. Transparency is generally reached at about 150-170 kbps (-q 5) (with some exceptions). The encoder is reasonably young and unoptimized, so further improvements can always be expected.<br />
<br />
Unfortunately, Xiph.org has failed to improve Vorbis at a steady rate since its initial 1.0 release in July 2002 (due to other developement projects and time constraints). Since then development has been led by other coders such as [http://sjeng.org/vorbisgt3.html Garf] and [http://www.geocities.jp/aoyoume/aotuv/ Aoyumi]. Aoyumi's '''[[aoTuV]]''' series of encoders was incorporated into the September 2004 release of 1.1, which brought about the first quality improvements across the board for 2 years. Currently Aoyumi is working on aoTuV Beta 5 and future releases. The latest version is aoTuV Release 1, which is the re-branded Beta 4.51 (released in December 2005). Unfortunately, the improvements of aoTuV Release 1 has not been incorporated yet into the 'official' Vorbis line.<br />
<br />
Vorbis has had success with many recent video game titles employing Vorbis as opposed to MP3 (with Epic Games' Unreal Tournament 2003 and Unreal Tournament 2004, the PC port of Microsoft's Halo and Uru being notable examples). Ogg Vorbis is also an official part of the [http://www.openal.org/extensions.html OpenAL] API extension library, used in many popular [http://www.openal.org/titles.html computer games]. On April 10, 2006, [http://www.radgametools.com/ RAD Game Tools] integrated Ogg Vorbis support to their Miles Sound System (MSS), which has been used in over 3,200 games worldwide. This ensures that future games utilizing MSS will have the capability to play Ogg Vorbis files. Check out [http://wiki.xiph.org/index.php/Games_that_use_Vorbis xiph wiki] for a full list of games confirmed to use Ogg Vorbis. <br />
<br />
Before encoding files using Ogg Vorbis, check out the [[Recommended Ogg Vorbis]] to determine what encoder to use and what settings are recommended by Hydrogenaudio. <br />
<br />
==Pros==<br />
* Ogg Vorbis specification is in the public domain; it is free for commercial or noncommercial use, under both (LGPL and BSD licenes)<br />
* Easy to use high-level API (Application Programming Interface)<br />
* Good all-round performance (>48 kbps - a leading codec at [http://www.rjamorim.com/test/multiformat128/results.html 128 kbps])<br />
* Well written [http://www.xiph.org/ogg/vorbis/docs.html specs]<br />
* Supported by most portable [[Ogg Vorbis#Supporting Digital Audio Players|DAPs]]<br />
* Suitable for internet-streaming (via [http://www.icecast.org/ Icecast] and other methods)<br />
* Fully [[gapless]] playback<br />
* High potential for further tuning<br />
* Structured to allow the design for a hybrid filterbank<br />
<br />
==Cons==<br />
* Limited official development (third-party developement is always encouraged)<br />
* Current implementations are more computationally intensive to decode than MP3<br />
* Multichannel input mappings for 5.1, Ambisonic-B, and other configs have no channel coupling and aren't tuned (expect sub-optimal results until code is improved)<br />
<br />
<br />
=Technical Information=<br />
* Multiple block sizes for window switching including overlap (powers of two only) ''(128/1024, 256/2048, 512/4096)''<br />
* Customly designed [[window function]] is applied similiar to the sine window. it has (good sidelobe rejection) <br />
:<font size="8pt"><math>w_k = \sin{(\frac{\pi}{2} \cdot sin^2[(\pi\div2n \cdot (k+0.5))]}</math></font><br />
* Psychoacoustics masking is exploited via an ([[ATH]] model)<br />
* Masking curves are computed from an ''emperically'' adjusted set of [http://www.zainea.com/masking2.htm Ehmer Curves]<br />
* Modified Discrete Cosine Transform ([[MDCT]]) is used for noise analysis<br />
* Fast Fourier Transform ([[FFT]]) is used for tonal analysis<br />
* Global masking curve is a mixture between calculated FFT+MDCT curves and ATH curves overlayed<br />
* Floor 1 or the noise-floor (envelope) is calculated using the global masking curve & piecewise linear approximation divided by spectrum to generate the residue (fine detail). The Levinson-Durbin [http://www.data-compression.com/speech.html#ana LPC model] in Floor 0 is no longer used, however the code still exists<br />
* [[Noise normalization]] is applied to compensate for energy lost in certain frequency bands due to quantization (rounding). <br />
* The channels are [[channel coupling|coupled]] ''strictly'' by residue using ([http://us.xiph.org/ogg/vorbis/doc/stereo.html point/phase stereo] and lossless)<br />
* Multistage [[Vector quantization]] is used for coding the noise-floor and residue backend using ''trained'' codebooks.<br />
* [[Huffman coding]] is used to minimize vector codeword redundancy<br />

=Introduction= <br />
'''Ogg Vorbis''' ([http://www.vorbis.com www.vorbis.com]) is a fully open, non-proprietary, patent-free (subject to [http://www.hydrogenaudio.org/forums/index.php?showtopic=13531 speculation]), and royalty-free, general-purpose compressed audio format for mid to high quality (8khz-48.0kHz, 16+ bit, [[multichannel]]) audio and music at fixed and variable bitrates from 16 to >256 kbps/channel. This places vorbis in the same competitive class as audio representations such as MPEG-4 ([[AAC]]), and similar to, but higher performance than [[MP3]], TwinVQ ([[VQF]]), [[WMA]] and [[PAC]]. Vorbis is the first of a planned family of Ogg multimedia coding formats being developed as part of Xiph.org's ogg multimedia project.<br />
<br />
Informal listening test suggests Vorbis to be comparable to MPEG-4 [[AAC]] at most bitrates and [[MPC]] at 128 kbps. Transparency is generally reached at about 150-170 kbps (-q 5) (with some exceptions). The encoder is reasonably young and unoptimized, so further improvements can always be expected.<br />
<br />
Unfortunately, Xiph.org has failed to improve Vorbis at a steady rate since its initial 1.0 release in July 2002 (due to other developement projects and time constraints). Since then development has been led by other coders such as [http://sjeng.org/vorbisgt3.html Garf] and [http://www.geocities.jp/aoyoume/aotuv/ Aoyumi]. Aoyumi's '''[[aoTuV]]''' series of encoders was incorporated into the September 2004 release of 1.1, which brought about the first quality improvements across the board for 2 years. Currently Aoyumi is working on aoTuV Beta 5 and future releases. The latest version is aoTuV Release 1, which is the re-branded Beta 4.51 (released in December 2005). Unfortunately, the improvements of aoTuV Release 1 has not been incorporated yet into the 'official' Vorbis line.<br />
<br />
Vorbis has had success with many recent video game titles employing Vorbis as opposed to MP3 (with Epic Games' Unreal Tournament 2003 and Unreal Tournament 2004, the PC port of Microsoft's Halo and Uru being notable examples). Ogg Vorbis is also an official part of the [http://www.openal.org/extensions.html OpenAL] API extension library, used in many popular [http://www.openal.org/titles.html computer games]. On April 10, 2006, [http://www.radgametools.com/ RAD Game Tools] integrated Ogg Vorbis support to their Miles Sound System (MSS), which has been used in over 3,200 games worldwide. This ensures that future games utilizing MSS will have the capability to play Ogg Vorbis files. Check out [http://wiki.xiph.org/index.php/Games_that_use_Vorbis xiph wiki] for a full list of games confirmed to use Ogg Vorbis. <br />
<br />
Before encoding files using Ogg Vorbis, check out the [[Recommended Ogg Vorbis]] to determine what encoder to use and what settings are recommended by Hydrogenaudio. <br />
<br />
==Pros==<br />
* Ogg Vorbis specification is in the public domain; it is free for commercial or noncommercial use, under both (LGPL and BSD licenes)<br />
* Easy to use high-level API (Application Programming Interface)<br />
* Good all-round performance (>48 kbps - a leading codec at [http://www.rjamorim.com/test/multiformat128/results.html 128 kbps])<br />
* Well written [http://www.xiph.org/ogg/vorbis/docs.html specs]<br />
* Supported by most portable [[Ogg Vorbis#Supporting Digital Audio Players|DAPs]]<br />
* Suitable for internet-streaming (via [http://www.icecast.org/ Icecast] and other methods)<br />
* Fully [[gapless]] playback<br />
* High potential for further tuning<br />
* Structured to allow the design for a hybrid filterbank<br />
<br />
==Cons==<br />
* Limited official development (third-party developement is always encouraged)<br />
* Current implementations are more computationally intensive to decode than MP3<br />
* Multichannel input mappings for 5.1, Ambisonic-B, and other configs have no channel coupling and aren't tuned (expect sub-optimal results until code is improved)<br />
<br />
<br />
=Technical Information=<br />
* Multiple block sizes for window switching including overlap (powers of two only) ''(128/1024, 256/2048, 512/4096)''<br />
* Customly designed [[window function]] is applied similiar to the sine window. it has (good sidelobe rejection) <br />
:<font size="8pt"><math>w_k = \sin{(\frac{\pi}{2} \cdot sin^2[(\pi\div2n \cdot (k+0.5))]}</math></font><br />
* Psychoacoustics masking is exploited via an ([[ATH]] model)<br />
* Masking curves are computed from an ''emperically'' adjusted set of [http://www.zainea.com/masking2.htm Ehmer Curves]<br />
* Modified Discrete Cosine Transform ([[MDCT]]) is used for noise analysis<br />
* Fast Fourier Transform ([[FFT]]) is used for tonal analysis<br />
* Global masking curve is a mixture between calculated FFT+MDCT curves and ATH curves overlayed<br />
* Floor 1 or the noise-floor (envelope) is calculated using the global masking curve & piecewise linear approximation divided by spectrum to generate the residue (fine detail). The Levinson-Durbin [http://www.data-compression.com/speech.html#ana LPC model] in Floor 0 is no longer used, however the code still exists<br />
* [[Noise normalization]] is applied to compensate for energy lost in certain frequency bands due to quantization (rounding). <br />
* The channels are [[channel coupling|coupled]] ''strictly'' by residue using ([http://us.xiph.org/ogg/vorbis/doc/stereo.html point/phase stereo] and lossless)<br />
* Multistage [[Vector quantization]] is used for coding the noise-floor and residue backend using ''trained'' codebooks.<br />
* [[Huffman coding]] is used to minimize vector codeword redundancy<br />

<div>2006-04-06 22h43 Norz: Hi! Best wishes to you & Vorbis! :)<br />
<br />
== Alright then ==<br />
<br />
So, my templates that the community has mostly used and help give an overview of articles are "stupid". Okay, fair game. The articles [[Ableton Live]], [[Ardour]]... are stupid. Stop making them.<br />
<br />
Polite, isn't it? {{User:Elliottmobile/sig2}} 03:22, 2 October 2006 (CDT)<br />
<br />
They are "stupid" in a sense that HA does no co-exist on the large scale that wikipedia does. Some of your templates are useful, but we have no use for your templates and the fact that you wish to enforce them on others. This is the only way you are making contributions to the wiki. Quite frankly it's annoying our wiki editors, my self included. Maybe you care to actually write some pages? yes? When Beto contributed the Software Infobox to the community he did it out of necessity. HA does not run things in the same manner the way wikipedia does. It's based upon the best interest of the community at hand. Are References necessary for pages? yes? can we expand the wiki based upon the particular interest of the community as a whole? yes? we can. Do we need to strictly enforce rules on a grand scale? no. There are only four to five dedicated user that make contributions to our wiki anyhow do the due to the time needed and the technical skills required to translate complicated matters into plain english. --[[User:HotshotGG|HotshotGG]] 16:19, 2 October 2006 (CDT)<br />
<br />
[http://wiki.hydrogenaudio.org/index.php?title=Special%3AContributions&offset=0&limit=50&target=Elliottmobile&namespace=0 A list of all my article-only contributions.] All I contribute is templates, now? {{User:Elliottmobile/sig2}} 14:59, 2 October 2006 (CDT)<br />
<br />
You are just moving stuff around and maintaining things from what I can tell by those edits. You are just contributing to the templates/maintenence nothing else. If you are only job is police the wiki like, such expect to recieve more critisism. You single handledly violated the wiki policy anyway, by interjecting personal opinion into a page that was unecessary. Save your opionions for your own personal user page and respect other people space. Once you have done so I will be a little more polite. I think a few others would agree. --[[User:HotshotGG|HotshotGG]] 17:25 2 October 2006 (CDT)<br />
