Foobar2000:Components/VST 2.4 adapter (foo vst)

'''VST 2.4 adapter''' is a component which aims to allow Foobar2000 users to use VST 2.4 plug-ins equally with “native” ones. Thousands of freeware and commercial DSP plug-ins are available in this format.
=Usage=
First, add VST plug-ins you would like to use in the VST manager: ''Preferences → Components → VST plug-ins''. Restart is required for the changes to take effect. After the restart open the [[Foobar2000:Preferences:Playback:DSP Manager|DSP Manager]] or some conversion dialog box to try the plug-ins you've added.

[[File:Preferences_VST_plug-ins.png|x185px]] → [[File:Preferences DSP Manager.png|x185px]] [[File:Converter Setup VST.png|x185px]]

Use ''View → DSP'' menu to access DSP configuration windows. Bind commands by their number to keyboard shortcuts if necessary.

[[File:Fb2k modeless dsp menu.png|x185px]] [[File:Preferences Keyboard Shortcuts DSP modeless.png|x185px]]

VST program file (.fxp) import/export items are in the system menu of editor windows (right click on the window's titlebar).

Microsoft Visual C++ 2008 Redistributable Package (x86) may be required for versions below 0.8.1

==Download==
See the attachment in the [https://hydrogenaud.io/index.php/topic,84947.0.html first post of the discussion thread].

==Features==
The component has support for the following feature set:
* Multiple instances
* Multiple channels (including asymmetric configs like 2.0 → 5.1)
* Chain presets and secondary DSP chains (“convert” feature)
* Modeless DSP configuration windows with [[Foobar2000:Preferences:General:Keyboard Shortcuts|keyboard shortcut binding]]
* FXP import/export
==Limitations and known issues==
* Limited to 20 VST entries due to API limitations (not to be confused with particular instances in a chain).
* No support for VSTs without custom editors yet (to be implemented in the near future).
* Display goes ahead of audio by the [[Foobar2000:Preferences:Output#Buffer_Length|size of the output buffer]].
* No x64 VST support: Foobar2000 is a 32-bit application. However, most effect plug-ins are available as 32 bit binaries.
* Modeless DSP configuration functionality isn't well synchronized with the DSP manager in the Preferences window.
* There are two versions labeled as v1.0 and v1.0.01 which are actually v0.1 and v0.2.
* At least older 0.9.0.3 version can cause playing mono files in only one channel

Most of these problems are caused by diametrically opposite approaches to the management of DSP objects lifetime. In contrast to VST, Foobar2000 assumes plug-in's user interface to be highly decoupled from the DSP code and the most difficult task solved by the adapter is coupling things back. Actually, such kind of DSPs as analyzers in fb2k is even impossible due to lack of connection between the GUI and audio rountines (of course one can have analyzers in form of visualization, but it's out of processing chain then). Foobar2000 recreates DSP objects whenever settings or playback state is changed, while in VST plug-ins are supposed to be loaded only once and their settings are to be changed ''directly'' with either automation or a editor window. Also in VST, plug-ins rely on their host in respect of number of channels, but in Foobar2000 it's the other way round, i.e. the host renders as many channels as a plug-in has. Finally, VST host must provide a window for the plug-in to create a editor and it's not supposed to block windows underneath while Foobar2000 requires config windows to be modal, etc.

Given all this, it must be clear that something had to be sacrificed for the sake of features listed above in the article. The adapter keeps track of current DSP chain to ensure proper threading and gapless playback, it abuses programming language features to overcome “one DSP service per class” principle, it adds random data to presets and looks for a window title before opening a editor to distinguish different instances of the same VST effect, it has advanced settings to deal with some other problems as well. In many ways the adapter's reliability is limited by these tricks, yet there are many faulty VST plug-ins around.

==Important notes==
* The adapter doesn't scan plug-ins at startup nor does it track changes in the VST directory. If some plug-in is absent then the adapter bypasses its processing.
* The component stores its settings in a separate binary file because of API limitations.

==Settings==
This component has only advanced settings placed in the corresponding section of Foobar2000 preferences. Depending on the component version they can be found either in the Playback or VST category (the latter is true for v0.6+). All the problems that mentioned here are caused by the differences between Foobar2000 and VST approaches to DSP implementation.
; ''Declicker size (256*n samples, 4 by default)''
: Number of zero samples to be passed through VST on transport switches to suppress plug-in's output data that can produce click at the beginning of the next track, i.e. ringing of filters or delay effect tail. The latter requires this number to be increased. Changes to this setting take effect after restart.

; ''Limit number of outputs''
: In contrast to DAW, audio players don't manage outputs of their DSPs. Besides, many VST plug-ins don't report activity of their outputs. Hence the only way to output data from 16-channel VST is to drop some of the channels according to the setting.

; ''VST idle time to unload DLL (0-10,000 ms)'' (0.7.1 and below)
: The delay is needed to suppress excessive unload-load cycles between tracks, i.e. to keep VST plug-ins loaded as it is supposed to be for them. In 0.8 the [un]loading strategy was revamped and this setting isn't necessary anymore.

==Change log==
'''0.9.0.3'''
* Fixed removal on the player updates

'''0.9'''
* Support for conversion and playback with same DSP chain presets
* Preset manager for each VST
* Per-instance channel number limit

== Description==
Filters the music to help reduce fatigue caused by listening to music with headphones.

=== Description from the developer ===
To help reduce listening fatigue caused by the unnatural stereo image provided by headphones, Crossfeed processes the left and right channels of stereo audio signals with a filter that mimics the sound absorption characteristics of the human head. After running through this filter, it then mixes a delayed portion of the left and right channels with each other to simulate the delay that occurs when listening to audio signals through stereo speakers positioned approximately 60 degrees apart from each other. The effect is subtle.

Dither

2023-10-26T15:07:24Z

TF3RDL:

{{stub}}
'''[[wikipedia:Dither#Digital audio|Dither]]''' is random or semi-random noise added to a signal in order to mask potential artifacts arising from quantization error and/or extend dynamic range. The simplest dither is quiet white noise, but more complicated forms of dither are possible using [[noise shaping]], and they can even be completely inaudible.

==Bit depth reduction==
A common use for dither is to improve the perceived audio quality when converting a digital signal from a higher bit depth to a lower one, e.g. from 24-bit to 16-bit. By dithering the signal with a small amount of added noise, the additional rounding error added from requantization can be decorreated from the signal, resulting in a noise floor that is mathematically slightly higher, but audibly less noticeable. The addition of dither becomes more important as the number of quantization levels decreases, and so is particularly important when converting to 8 bit or lower audio.

==Is dither really necessary?==

Going from 24-bit to 16-bit, the quantization error is very small and the distortion/noise is extremely unlikely to be heard in any real music. Since quantization error isn’t audible in any real music at useable listening levels, whether dither must be used is more a matter of doctrine than functionality.

Many sources (e.g. cassettes and LPs) already have considerable noise such as tape hiss. Even the best live recordings get some noise from the equipment, especially microphone preamplifiers. This might not make the best dither, but it acts in the same way, to largely de-correlate the quantization error from the signal.

Anyone who believes dither is always necessary for conversions to 16-bit should submit, on the HydrogenAudio forums, samples that can be discriminated in blind testing, lest they earn [[TOS 8]] violations.

Foobar2000:Components/WASAPI output support (foo out wasapi)

2023-10-22T18:27:20Z

TF3RDL: use the legacy components category

{{infobox foobar2000 component
| name = WASAPI output support

}}
The '''Windows Audio Session API (WASAPI) output support''' component allows you to play your music using WASAPI exclusive mode.

WASAPI is a new audio output method introduced in Windows Vista; among other things, it provides an exclusive mode that allows applications to take full control over soundcard's resources (muting any sounds played by other applications) and play unaltered bitstream without passing it through the Windows mixer.

== Differences between WASAPI and [[Foobar2000:Components 0.9/ASIO support|ASIO]] / [[Foobar2000:Components 0.9/Kernel Streaming Output (foo out ks)|Kernel Streaming]] from foobar2000 user’s perspective ==
* Requires Windows Vista or Windows 7 - not available on Windows XP or older.
* Works with more soundcards - contrary to e.g. ASIO, it doesn't require any special support from soundcard's manufacturer, other than providing a Windows Vista compatible driver.
* Guarantees muting of any other sounds played through the soundcard - with ASIO and KS, muting occurred with some soundcards but not with all of them; it was a side effect rather than a feature.

== WASAPI plug-in version 3.0 ==
=== Output modes: push and event-driven ===
As for the latest version of the component, two different output modes are available - push and event-driven; certain soundcards - especially USB devices - are known to cooperate better with the event-driven mode while certain other soundcards do not support the event-driven mode at all.

=== Sandbox ===
Unfortunately, WASAPI is affected by various bugs in both Windows mixer and soundcard drivers. To keep these from crashing foobar2000, all WASAPI access is now sandboxed in a separate process for better stability.

== Buffer size tweaks ==
Please note that any buffer tweak options ''do not'' explicitly cause the specified buffer size to be used; if the specified value is outside the allowed range for your device, the nearest allowed value will be used.

* Takes impulse response and does a fast convolution of the sound data with that impulse response.
* Allows quick computation of any combination of linear effects, such as equalization, echo, flange, reverb, phase shift and so on.

'''VST 2.4 adapter''' is a component which aims to allow Foobar2000 users to use VST 2.4 plug-ins equally with “native” ones. Thousands of freeware and commercial DSP plug-ins are available in this format.
=Usage=
First, add VST plug-ins you would like to use in the VST manager: ''Preferences → Components → VST plug-ins''. Restart is required for the changes to take effect. After the restart open the [[Foobar2000:Preferences:Playback:DSP Manager|DSP Manager]] or some conversion dialog box to try the plug-ins you've added.

[[File:Preferences_VST_plug-ins.png|x185px]] → [[File:Preferences DSP Manager.png|x185px]] [[File:Converter Setup VST.png|x185px]]

Use ''View → DSP'' menu to access DSP configuration windows. Bind commands by their number to keyboard shortcuts if necessary.

[[File:Fb2k modeless dsp menu.png|x185px]] [[File:Preferences Keyboard Shortcuts DSP modeless.png|x185px]]

VST program file (.fxp) import/export items are in the system menu of editor windows (right click on the window's titlebar).

Microsoft Visual C++ 2008 Redistributable Package (x86) may be required for versions below 0.8.1

==Download==
See the attachment in the [https://hydrogenaud.io/index.php/topic,84947.0.html first post of the discussion thread].

==Features==
The component has support for the following feature set:
* Multiple instances
* Multiple channels (including asymmetric configs like 2.0 → 5.1)
* Chain presets and secondary DSP chains (“convert” feature)
* Modeless DSP configuration windows with [[Foobar2000:Preferences:General:Keyboard Shortcuts|keyboard shortcut binding]]
* FXP import/export
==Limitations and known issues==
* Limited to 20 VST entries due to API limitations (not to be confused with particular instances in a chain).
* No support for VSTs without custom editors yet (to be implemented in the near future).
* Display goes ahead of audio by the [[Foobar2000:Preferences:Output#Buffer_Length|size of the output buffer]].
* No x64 VST support: Foobar2000 is a 32-bit application. However, most effect plug-ins are available as 32 bit binaries.
* Modeless DSP configuration functionality isn't well synchronized with the DSP manager in the Preferences window.
* There are two versions labeled as v1.0 and v1.0.01 which are actually v0.1 and v0.2.
* At least older 0.9.0.3 version can cause playing mono files in only one channel

Most of these problems are caused by diametrically opposite approaches to the management of DSP objects lifetime. In contrast to VST, Foobar2000 assumes plug-in's user interface to be highly decoupled from the DSP code and the most difficult task solved by the adapter is coupling things back. Actually, such kind of DSPs as analyzers in fb2k is even impossible due to lack of connection between the GUI and audio rountines (of course one can have analyzers in form of visualization, but it's out of processing chain then). Foobar2000 recreates DSP objects whenever settings or playback state is changed, while in VST plug-ins are supposed to be loaded only once and their settings are to be changed ''directly'' with either automation or a editor window. Also in VST, plug-ins rely on their host in respect of number of channels, but in Foobar2000 it's the other way round, i.e. the host renders as many channels as a plug-in has. Finally, VST host must provide a window for the plug-in to create a editor and it's not supposed to block windows underneath while Foobar2000 requires config windows to be modal, etc.

Given all this, it must be clear that something had to be sacrificed for the sake of features listed above in the article. The adapter keeps track of current DSP chain to ensure proper threading and gapless playback, it abuses programming language features to overcome “one DSP service per class” principle, it adds random data to presets and looks for a window title before opening a editor to distinguish different instances of the same VST effect, it has advanced settings to deal with some other problems as well. In many ways the adapter's reliability is limited by these tricks, yet there are many faulty VST plug-ins around.

==Important notes==
* The adapter doesn't scan plug-ins at startup nor does it track changes in the VST directory. If some plug-in is absent then the adapter bypasses its processing.
* The component stores its settings in a separate binary file because of API limitations.

==Settings==
This component has only advanced settings placed in the corresponding section of Foobar2000 preferences. Depending on the component version they can be found either in the Playback or VST category (the latter is true for v0.6+). All the problems that mentioned here are caused by the differences between Foobar2000 and VST approaches to DSP implementation.
; ''Declicker size (256*n samples, 4 by default)''
: Number of zero samples to be passed through VST on transport switches to suppress plug-in's output data that can produce click at the beginning of the next track, i.e. ringing of filters or delay effect tail. The latter requires this number to be increased. Changes to this setting take effect after restart.

; ''Limit number of outputs''
: In contrast to DAW, audio players don't manage outputs of their DSPs. Besides, many VST plug-ins don't report activity of their outputs. Hence the only way to output data from 16-channel VST is to drop some of the channels according to the setting.

; ''VST idle time to unload DLL (0-10,000 ms)'' (0.7.1 and below)
: The delay is needed to suppress excessive unload-load cycles between tracks, i.e. to keep VST plug-ins loaded as it is supposed to be for them. In 0.8 the [un]loading strategy was revamped and this setting isn't necessary anymore.

Foobar2000:Components 0.9/Panel Stack Splitter (foo uie panel splitter)

TF3RDL: Panel Stack Splitter is such an old component

Panel Stack Splitter is a ColumnsUI extension for advanced placement and scripting of panels. It functions as a splitter in the ColumnsUI panel hierarchy (i.e., it can contain other panels).

= Function and Use =
Panel Stack Splitter is an extension for ColumnsUI which allows for greater control over the arrangement of panels. Not only can any panel be positioned freely within the Foobar2000 window, but the splitters themselves can be scripted, the panels can be resized using the cursor or by scripted actions, and panels can be hidden and displayed according to your script. It includes functions which make it easy to create graphical buttons and dynamic layouts. It can replace any number of more specific panels, such as those intended for displaying album art or track information.

Common uses include the creation of interfaces which reconfigure themselves automatically depending on the window size, panel-switching arrangements, and of course, all manner of window dressing. It's often used alongside other plugins such as [[Foobar2000:Components 0.9/ELplaylist panel (foo uie elplaylist) | ELPlaylist]] and [[Foobar2000:Components 0.9/WSH panel (foo uie wsh panel)| WSH Panel]] to construct elaborate custom interfaces, but be warned that the results of such efforts are, unlike Foobar2000 itself, not always efficient or stable.

= Authorship =
Panel Splitter was written by '''ssenna''', who is also the author of [[Foobar2000:Components 0.9/ELplaylist panel (foo uie elplaylist) | ELPlaylist]]. Many of the functions are similar and both plug-ins work well together.

= Requirements =
* foo_uie_panel_splitter.dll v0.3.8.3a (2009/12/11)
* [http://www.foobar2000.org/ foobar2000 v0.9.5.2+]
* [http://yuo.be/columns.php Columns UI 0.3+]

= Reference =
The following documentation is an imperfect translation and adaptation from the original Japanese readme. Until the page has been more thoroughly re-written, expect some confusing passages.

== Introduction ==
After installing the plug-in, in the options dialog under ColumnsUI's Layout tab you'll be able to add a Panel Stack Splitter to your layout and configure it. Once you've added a Panel Stack Splitter you can also edit it by right-clicking the panel and choosing ''Configure'' from the context menu. The relationship between Panel Stack Splitters and the resulting layout may initially be confusing. In theory, one could place all their panels under a single Panel Stack Splitter to achieve any layout, but in practice you will generally want to employ them more like traditional horizontal and vertical splitters, nesting hierarchically.

== Splitter Settings dialog ==
The Splitter Settings dialog has four tabs, ''PanelList, Script, Behavior'' and ''Global variables''.

''PanelList'' shows subordinate panels and allows you to define their names, positions and sizes. ''Script'' allows you to script the Splitter panel itself; this is where you would define buttons, text to display, or scripts which alter the layout or operate invisibly. ''Behavior'' presents options related to how the Splitter is rendered and how it executes scripts, and ''Global variables'' lets you view and delete currently active global variables. 

=== PanelList ===
You can't add subordinate panels from this tab -- for this you must return to the ColumnsUI layout options. But once you've added panels, you can select them from the left box in this tab and define their display parameters at the right. Note that there is one option on this tab which is for the Splitter itself rather than its children; this is ''Panel placement mode'', which allows you to select horizontal or vertical position. This parameter is irrelevant for forced layouts.

All fields accept numbers as pixel positions and widths by default, though you can switch to percentage values instead when in forced mode. You can use Titleformatting Script in all of these fields, which is often important for forced layouts if you want them to be resizeable.

; Caption : This allows you to assign a unique name to the panel in question. In addition to providing a convenient label for the panel for when you're editing, this allows you make direct reference to the panel is scripts later on, for example if you wanted to display, hide or resize it.
; Size : Defines the size of the panel, but only if you are using a non-forced layout. Size means width when in horizontal panel placement mode and height when in vertical panel placement mode.
; Padding : These values define padding between the edges of the panel's allotted space (''size'') and the actual panel.
; Lock size : This disables the user from resizing the panel using the mouse. Only applies to non-forced layout mode; in forced-layout mode this is already default. The original documentation provides further details about this option, including a caveat that seems to address the possibility of blurred pixels, but the auto-translation is garbled.
; Forced layout : This option allows you to directly determine the position and size of a panel. Turning it on disables ''Size'' and (by default) padding and makes ''panel placement mode'' irrelevant. Panels can even overlap, though you generally would only want to do this if you intend to provide a way to switch between them. Left and Right are measurements from the upper-left (0,0) of the panel.
:* [[Foobar2000:Title Formatting Reference | Title Formatting script]] is enabled and you can use <tt>%_width%</tt> and <tt>%_height%</tt> to call the current width and height of the Splitter itself.
:* If two panels overlap, by default the one that renders in front is determined by the sequence of panels as defined in the ColumnsUI options. ''[?]''
:* '''Example.''' This would always expand the panel to the width of the splitter minus 400 pixels:
Width: $sub(%_width%,400)
:* '''Example.''' This would make the panel always fill the lower half of the available space:
Top: $div(%_height%,2)
Height: $div(%_height%,2)
; Use percentage value : This option makes Panel Splitter interpret the values in Left, Top, Width and Height as percentages of available space instead of pixel measurements. Thus the second example above could be written as ''Top: 50'' and ''Height: 50''.
; Enable padding settings: This option re-enables the padding values defined for non-forced-layout mode. Though this may seem redundant when you can simply include the padding in your position and size values, it may be useful for percentage-based layouts.
; Ignore panel size limits : ''This seems to be undocumented'', but allows for sizes lower or higher than default caps. For example, the seekbar will display as 20px high if any value below 20px is entered into the Height field unless this box is checked.
; Hide panel on startup : This rather straight-forward option does precisely what its name indicates. To later make the panel visible, you would use a script function such as <tt>$showpanel_c</tt>.


=== Script Tab ===

titleformat mode on startup: when you start the TitleFormat PerTrack modes.
* now playing TF play that track
* follow cursor on the selected tracks in playlist
* last mode at the end of the previous mode (the switch mode button to save)

* title formatting script:
Titleformat here to describe, and decorative backgrounds. However, the child is on the panel can not be drawn.

Extended Command Reference

=== $imageabs(x,y,w,h,path,OPTIONS,n,alpha,OPTIONS2) ===

Displays an image '''(path)''' at coordinates '''(x,y)''' with size '''(w,h)'''. By default, an image is expanded to the maximum size allowed by (w,h) without changing the aspect ratio of the image. After the image has been resized (if indeed it has been), the resized version is cached in the memory, which means any further references to it will return the modified rather than original values. 


'''Path''' is the absolute path of the image. It can also point to an audio file if it has an embedded image or if you are using one of the "artreader" options, and the path can include compressed archives if the "archive" option is active (see below).

'''Options''' are flags which you separate with a space.
* '''Resizing options'''
** ''nokeepaspect'' ignores the image's aspect ratio and expands the image to fill both width and height regardless of distortion ''(nodisplay, archive, icon options and non-exclusive) [?]''
** ''noexpansion'' prevents resizing to fill the space if the image turns out to be smaller than the specified width and height.

* '''Alignment options'''
** ''left'' and ''right'' determine horizontal alignment (left is default).
** ''top'' and ''bottom'' determine vertical alignment (top is default).

* '''Miscellaneous options'''
** ''wc'' enables wildcard characters (*,?).
** ''nodisplay'' caches the image without actually displaying it.

* '''Read-mode (path-related) options'''
** ''archive'' allows references to compressed archives to be included in the path. The path format is the absolute path of the archive followed by the base path within the archive file, using a pipe (|) as the separator. For example: ''C:\aaa\image.zip|bbb/ccc.jpg''
** ''icon'' indicates that the path is specified in the icon file (*.ico) ''[?]''.
** ''artreader'' uses embedded images or the default album art paths you've defined in Foobar2000's options to determine the image to be displayed. The path supplied should be that of an audio file (typically, this would be %path%). 
*** ''artreader_front, artreader_back, artreader_disc'' and ''artreader_icon'' are variations on this option which select the specific corresponding album art. However, the original documentation suggests one avoid these options because they seem to be slow. 

'''n''': rotateflip Index for:
* ''1'': 90°
* ''2'': 180°
* ''3'': 270°
* ''4'': flip horizontal
* ''5'': 90° + flip horizontal
* ''6'': Flipped vertically
* ''7'': 90° + Flip Vertically

'''Alpha''' (Opacity)

Free Lossless Audio Codec

2023-10-20T00:32:14Z

TF3RDL: /* Cons */ FLAC only supports up to 32-bit integer, and no floating-point support unlike WavPack

{{Codec Infobox
| name = FLAC
| logo = [[Image:FLAC logo.gif]]
| type = lossless
| purpose = Popular open source patent free lossless compression scheme.
| maintainer = Josh Coalson, Xiph Community
| released = {{start date and age|2001}}
| recommended_encoder = FLAC encoder
| recommended_text = FLAC v1.4.3 (23 Jun 2023)
| website = http://xiph.org/flac/
}}
'''Free Lossless Audio Codec''' ('''FLAC''') is a codec for lossless audio compression.
Grossly oversimplified, 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, if supported) just like you would a lossy file.

FLAC is natively supported in Android since version 3.1, in Windows 10, and in macOS High Sierra 10.13.

== General aspects of the format ==
FLAC is freely available and supported on most operating systems, including Windows, UNIX (Linux, *BSD, Solaris, OS X, IRIX), BeOS, OS/2, and Amiga. There are build systems for autotools, MSVC, Watcom C, and Project Builder.

The FLAC project consists of:
* the stream format
* reference encoders and decoders in library form
* flac, a command-line program to encode and decode FLAC files
* metaflac, a command-line metadata editor for FLAC files
* input plugins for various music players

When it's said that FLAC is ''free'', it means more than just that it is available at no cost. It means that the specification of the format is fully open to the public to be used for any purpose, although the FLAC project reserves the right to set the FLAC specification and certify compliance. It also means that neither the FLAC format nor any of the implemented encoding/decoding methods are covered by any known patent. And it means that all the source code is available under [http://xiph.org/flac/license.html open-source licenses]. It is the first truly open and free lossless audio format.

== Features ==
* '''Lossless:''' The encoding of audio (PCM) data incurs no loss of information, and the decoded audio is bit-for-bit identical to what went into the encoder. Each frame contains a 16-bit CRC of the frame data for detecting transmission errors. The integrity of the audio data is further insured by storing an MD5 signature of the original unencoded audio data in the file header, which can be compared against later during decoding or testing.
* '''Fast:''' FLAC is asymmetric in favor of decode speed. Decoding requires only integer arithmetic, and is much less compute-intensive than for most perceptual codecs. Real-time decode performance is easily achievable on even modest hardware.
* '''Hardware support:''' Because of FLAC's free reference implementation, low decoding complexity and popularity, FLAC has relatively widespread hardware support compared to other lossless formats.
* '''Streamable:''' Each FLAC frame contains enough data to decode that frame. FLAC does not even rely on previous or following frames. FLAC uses sync codes and CRCs (similar to MPEG and other formats), which, along with framing, allow decoders to pick up in the middle of a stream with a minimum of delay.
* '''Seekable:''' FLAC supports fast sample-accurate seeking. Not only is this useful for playback, it makes FLAC files suitable for use in editing applications.
* '''Flexible metadata:''' New metadata blocks can be defined and implemented in future versions of FLAC without breaking older streams or decoders. Currently there are metadata types for tags, cue sheets, and seek tables. Applications can write their own APPLICATION metadata once they register an ID.
* '''Suitable for archiving:''' FLAC is an open format, and there is no generation loss if you need to convert your data to another format in the future. In addition to the frame CRCs and MD5 signature, FLAC has a verify option that decodes the encoded stream in parallel with the encoding process and compares the result to the original, aborting with an error if there is a mismatch.
* '''Convenient CD archiving:''' FLAC has a ''cue sheet'' metadata block for storing a CD table of contents and all track and index points. For instance, you can rip a CD to a single file, then import the CD's extracted cue sheet while encoding to yield a single file representation of the entire CD. If your original CD is damaged, the cue sheet can be exported later in order to burn an exact copy.
* '''Error resistant:''' Because of FLAC's framing, stream errors limit the damage to the frame in which the error occurred, typically a small fraction of a second worth of data. Contrast this with some other lossless codecs, in which a single error destroys the remainder of the stream.

== Pros ==
* Portable to many systems
* Open source and freely licensed
* Hardware support (PhatBox, Kenwood MusicKeg, Rio Karma, etc. See below)
* Streaming support
* Extremely fast decoding
* Supports multichannel and high resolution streams
* Supports [[ReplayGain]]
* Supports cue-sheet (with some limitations)
* Gaining wide use as successor to [[Shorten]]

== Cons ==
* Compresses less efficiently than other popular modern compressors ([[Monkey's Audio]], [[OptimFROG]])
* Higher compression modes slow, for little gain over the default setting.
* Only integer bit depth (up to 32-bit int) format are supported, or in other words, no floating-point support.

== Frequently asked questions ==
''Question:'' Does the compression level affect decompression speed?

''Short Answer'': No.

''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.

''Question:'' What is the best compression level for encoding my music?

''Short Answer'': The default setting, 5.

''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.

{{fb2k}}
[[Image:Foo_vis_shpeck-milkdrop2.jpg|thumb|256px|Example of MilkDrop 2 running in Shpeck]]

'''Shpeck''' is a wrapper for Winamp's visualisation plugins, using either a stand-alone window, a Columns UI panel or Default UI element. Winamp itself does not need to be installed. Only one plugin can be active at once, though - that is a limitation of the original design.

Shpeck shouldn't be used with other Winamp emulators because of possible conflicts. The recommended solution is to keep Shpeck only - because it supports the biggest number of Winamp's features among these emulators, it shouldn't be a problem.

Winamp is a registered trademark of Nullsoft. Various third-party plugins are owned by their developers and their usage is restricted by their respective licenses.

== Preferences ==
[[Image:Foo_vis_shpeck-prefs.png|thumb|256px|Shpeck preferences page.]]

=== Winamp directory ===
Specifies the base directory of Winamp installation, i.e. the folder with "winamp.exe". Shpeck scans its "Plugins" subdirectory for plugin DLLs and this path is also passed to loaded plugins (they use it to store their configuration in "%WINAMP_DIR%\Winamp.ini" file, for example).
Default value is "C:\Program Files\Winamp".

Note that Winamp itself doesn't need to be installed - you can choose any directory as long as there is a "winamp.exe" file in it (even empty) and a "Plugins" folder with installed plugins in it.

To avoid the standard Windows "Browse For Folder..." dialog and enter the path directly (e.g. to enter sophisticated network path), click on the [...] button with SHIFT key pressed.

=== Available plugins ===
This area contains a list of visualisation plugins detected in the folder chosen above. Each DLL can contain several different visualisation modules, hence the names are in form "Plugin name / Module name".
Buttons on the right allow to configure or start currently selected module, stop the running one (if any) and refresh the list.

If some installed plugins don't appear in the list, it might be because of their unresolved dependencies. For example, "MilkDrop 2" or "NSFS" plugins need file NSCRT.DLL from Winamp installation to run. Both the folder with plugin itself and directory with "foobar2000.exe" is searched, so copying the library to either place should help.

{{panel|'''Note''': As of Winamp version 5.57, NSCRT.DLL was depreciated and no longer included with installation. It is included in the Winamp version 5.55 installation.|color=yellow}}

=== Options ===
==== Title bar for embedded windows ====
Plugins running in an emulation of Winamp 5+ "embedded window" can show a title bar displaying current plugin name and a few controls, e.g. to change presets. If the title bar is enabled, it is possible to change background color, title text color, title font and button images.

The buttons image must be a BMP file with width divisible by 5 (for five buttons - previous preset, next preset, random preset mode, fullscreen toggle and context menu) and height divisible by 3 (for three states - normal, hover and pushed). 32-bit format with alpha/opacity is supported.
The height of resulting title bar is the height of buttons or selected font, whichever is bigger.

Defaults are colors and font from Windows desktop settings and internal semi-transparent buttons.

Title bar settings for Columns UI panels and Default UI elements are configured in their Appearence dialog, accessible from their context menu (right-click on a title bar).

==== Other ====
By default, visualisation's thread priority is lowered below normal, as visualisations are considered to be just an additional eye candy. The option to disable this behavior might help in cases when some background process generates non-uniform peaks in CPU usage and visualisations stutter from time to time. (This applies to virtually single-processor systems only.)

=== Title formatting ===
This section specifies the title formatting to be used for reporting current track title and playlist entries. See "foobar2000 Main Menu > Help > Title Formatting Help" for more information about title formatting syntax.

The "Current track" format affects the title of fake Winamp window, which is visible from other applications, e.g. "now-playing plugins".

Foobar2000:Components 0.9/Peakmeter Spectrum (foo uie vis peakmeter spectrum)

2023-10-05T01:21:36Z

TF3RDL: Peakmeter Spectrum is obsolete

{{fb2k}}
[[Category:Foobar2000 3rd-party components (legacy)|Peakmeter Spectrum]]
[[Category:Foobar2000 visualization components (legacy)]]

==Description==
Foo_uie_peakmeter_spectrum is a foobar2000 plugin that combines a peakmeter with a spectrum analyzer. It requires Columns UI and is the successor of foo_uie_peakmeter. It can be used as a peakmeter and/or a spectrum analyzer.

==Requirements==
This component is only available as a Columns UI panel and it is not available as a Default UI element, therefore it requires [[foobar2000:Components/Columns UI (foo_ui_columns)|Columns UI (foo_ui_columns)]].

==Installation==
#Extract the downloaded archive and place foo_uie_vis_peakmeter_spectrum.dll in your foobar2000 "components" folder (normally located at %ProgramFiles%\foobar2000\components\).
#Start foobar2000.
#Open up '''File/Preferences''', navigate to '''Display''' -> '''Columns UI''', and select the '''Layout''' tab.
#Right-click on a splitter and select '''Insert Panel''' -> '''Visualisations''' -> '''Peakmeter Spectrum'''
#Click '''Apply''' to make the panel appear.

=Import and export settings=
To open a preset or a settings file please right click on the component and select import. Then you have to select the location of the desired file.

To save your settings to a file please right click on the component and select export. Then you have to select the location of the desired file.

=Specification=
[[Image:peakmeter_spectrum_description.jpg|589px]]
==Elements==

====main bar====
You can customize the settings of the main bar in the goup "Main bar" of the preference dialog. Right click on the component and select "Preferences" to show the dialog. The size can be set individually for the spectrum analyzer and the peakmeter by clicking the button "Options" in the corresponding group.
====additional bar====
The additional bar is only available for the peakmeter. The settings can be customized by clicking the button "Options" in the Peakmeter group.
====bar label====
The bar label can be hidden by deselecting the Show bar label check box in the goup "Main bar". Colors can be configured by clicking the button "Colors" in the group "Global".
====peak indicator====
Peak indicator settings can be customized by clicking the button "Peak indicator" in the group "Main bar".
===Peakmeter===
The peakmeter indicates the instantaneous level of an audio signal.

The visible channels can be configured by selecting the appropriate item in the peakmeter channel listview and clicking the button "Edit".

Additional settings can be accessed through the button "Options" in the peakmeter group. In the peakmeter options dialog you can select between peak and [http://en.wikipedia.org/wiki/Root_mean_square rms] display.

===Spectrum analyzer===
The spectrum analyzer observes the frequency characteristics of the foobar audio output signal in real time.

You can specify the visible frequency bands by selecting or deselecting them in the spectrum analyzer list view. In addition to this there are three Buttons below the band list view, which can be used to select a part or all bands. Button "A" will select all bands. Button "2" will select every second band. Button "4" will select every forth band.

By pressing the Button “Options” in the spectrum analyzer group you can customize the accuracy and select or deselect the audio channels. [http://en.wikipedia.org/wiki/Fast_Fourier_transform FFT size] and the [http://en.wikipedia.org/wiki/Window_function window function] have a great influence on the quality of result.

=Description=
TagBox is a tag editing UI element and standalone window. It lets you quickly modify the meta data of music files (title, artist name, album name, etc.) through a UI element which you can place anywhere in your foobar2000 interface layout - so no pop-up dialog needed.

[[Image:tagbox_in_use.png]]

=Installation=
Download the plugin from [https://www.foobar2000.org/components/view/foo_tagbox TagBox component page] and open it e.g. by double clicking it. foobar2000 opens and asks for confirmation to install the component. Click ''Apply'' or ''OK'' and let foobar2000 restart to activate. Open ''menu bar > View > Layout > Enable layout editing mode'' or ''Create Scratchbox'' to place TagBox element somewhere in your layout; e.g. after selecting ''Enable layout editing mode'', right click e.g. ''Metadata'' UI element, select ''Replace UI element...'' and click ''TagBox'', confirm with ''OK'' and fixate the layout by ''menu bar > View > Layout > Enable layout editing mode''.

=Configuring TagBox=
To configure a TagBox UI Element: Click the tools button (gear icon) and select ''Configuration''.

To configure TagBox's standalone window: Go to ''menu bar > Preferences > Tools > Tagging > TagBox''.

[[File:Tagbox configuration.png]]

* Predefined values (enumeration of all possible values like genres, ratings etc.) are ; separated. Spaces after ; are not written into metadata fields.
* If you check ''Immediately Apply'', the change caused by using a predefined value is immediately applied to the file. Note: Seems not to work in all newer versions of foobar2000 / Windows, see [https://hydrogenaud.io/index.php?topic=81194.200 discussion thread].

=Using TagBox=
* All fields accept ; separated multiple values.
* If there is only one track selected, pressing the ''Up/Page Up'' and ''Down/Page Down'' keys when editing a field moves the selection to the previous/next track in playlist and selects all the text in that field.
* Pressing ''Enter'' applies the changes.
* Pressing ''Ctrl+Enter, Ctrl+Down'' or ''Ctrl+Page Down'' when only one track is selected applies the change and moves the selection to next track in play list.
* In the drop-down list next to a field, you can also find tag specific functions like ''Correct Capitalization'' or ''Auto Track Number'' etc.
* Global operations like ''Filename -> Tag'' are accessible through the tools menu (gears icon).
* In the preferences page, you can choose whether ''Down'' key opens the drop-down menu and ''Page Down key'' moves the selection down or vice versa.

Constant-Q transform

[[File:constant q transform.png|thumb|256px|A constant-Q spectrogram. Notice that lower frequencies (the bottom part) having horizontal/time-axis blur.]]
[[File:short time fourier transform.png|thumb|256px|In comparison, the constant-bandwidth version of Goertzel algorithm spectrogram have same time-axis blur for all frequencies (vertical slices), but it is blurrier in vertical axis at bottom part of the spectrogram.]]
'''Constant-Q''' and '''variable-Q transforms''' ('''CQT/VQT''') are spectral analysis algorithms that usually have logarithmic frequency spacing and time/frequency resolution following octave series. Due to its usually logarithmic frequency resolution, it is suited for musical representation.

== Overview ==
{{panel|More details are available on [[wikipedia:constant-Q transform|a Wikipedia page about the same topic]].|color=green}}
Usually, the [[Fast Fourier Transform|FFT]] are linearly-spaced in frequency and are constant-bandwidth, which is better suited for perfect reconstruction, however, due to the fact musical notes are logarithmically-spaced and how auditory perception works, the FFT is not suited for anything musical even though it is used in some RTA analyzers.

The constant-Q transform can be constructed using multi-band Goertzel algorithm with each one has its own window size; lower frequencies have larger window size and vice versa, and with logarithmic frequency spacing (a 120-band Goertzels covering 20Hz-20kHz range and each band corresponds to musical notes). However, while the auditory perception are non-linear, it is not exactly logarithmic as the pitch perception is linear and constant-bandwidth at bass region.<ref>Christian Schörkhuber, Anssi Klapuri, Nicki Holighaus, Monika Dörfler (2014). [https://www.researchgate.net/publication/274009051_A_Matlab_Toolbox_for_Efficient_Perfect_Reconstruction_Time-Frequency_Transforms_with_Log-Frequency_Resolution A Matlab Toolbox for Efficient Perfect Reconstruction Time-Frequency Transforms with Log-Frequency Resolution].</ref>

[[File:variable q spectrogram.png|thumb|256px|Variable-Q transform have benefits of better temporal resolution at lower frequencies (albeit with slightly bad frequency resolution at lower frequencies), just like traditional STFT while having pseudo-logarithmic resolution at higher frequencies.]]
[[File:constant q spectrogram.png|thumb|256px|In comparison, the CQT version have poor time resolution on lower frequencies but it has sharper frequency-axis resolution than VQT version.]]

Additionally, the gamma parameter can be used to gradually reduce the Q factor for lower frequencies to improve temporal resolution for that region. Alternatively, the band spacing can be set to perceptual frequency scales like Mel and Bark but it works best when the bandwidth is set according to '''abs(high - low)''' for each band. Either way, this becomes a variable-Q transform.<ref>Filip ZAPLATA, Miroslav KASAL (2015). [https://www.researchgate.net/publication/276076772_Efficient_Spectral_Power_Estimation_on_an_Arbitrary_Frequency_Scale Efficient Spectral Power Estimation on an Arbitrary Frequency Scale].</ref>

Although FFT itself can be used in conjunction with frequency-domain kernels, calculating a CQT directly is slow even with Goertzel algorithm unless a [[sliding DFT]] is used.

A high-quality resampling for 64-bit version of foobar2000 v2.0 and later.

== Description ==
PGGB-RT/foobar (foo_pggb_rt) offers high accuracy resampling. It operates as a stream renderer while foobar2000 handles the input decoding and output audio driver interfaces. As a track is playing, foo_pggb_rt processes the next track in the playlist so it's ready as needed, for real-time performance and a gapless playback experience.

A 64-bit version of Windows (or Windows 11) operating system is required with at least 16GB of RAM is recommended.
