==Software Needed==
* [http://exactaudiocopy.org/eac6.html Exact Audio Copy]
* [http://www.rarewares.org/dancer/dancer.php?f=1 Lame 3.90.3]
'''OR'''
* [http://rarewares.org/dancer/dancer.php?f=2 Lame 3.96.1]

Note: Although LAME is being continuously developed, the version that is extensively tested and recommended here at hydrogenaudio.org is version 3.90.3. So, you may want to stick with that version for now until a later version is tested and recommended.

==Installation==
'''Note:''' This guide assumes that EAC is has been configured for secure ripping, if not please follow [[EAC_Drive_Configuration | this]] guide.
* Unzip the chosen lame version into the same directory that EAC is in.

==Configuration==

* Open EAC and insert a CD into the drive.
* Click the '''EAC''' menu and select '''Compression Options'''.
* Click the '''External Compression''' Tab, and put a check box in '''use external program for compression'''.
* Change '''Parameter Passing Scheme''' to '''User Defined Encoder'''.

* Click the '''Browse''' button and locate the '''LAME.EXE''' that you unzipped earlier.
* Remove the ticks from '''Use CRC check''', '''Add ID3 tag''' and '''check for external programs return code'''.
* Do not worry what bit rate is shown in the '''Bit rate''' drop down box as this will not have any effect on the resultant MP3 file (See Note 4 at the bottom of this page).

* In the '''Addtional command line options''' box, copy and paste one of the below strings based on the Tag you would prefer.
'''No Tags:'''

'''--alt-preset standard''' %s %d

'''ID3v1:'''

'''--alt-preset standard''' --id3v1-only --ta "%a" --tt "%t" --tl "%g" --ty "%y" --tn "%n" %s %d

'''ID3v2:'''

'''--alt-preset standard''' --id3v2-only --pad-id3v2 --ta "%a" --tt "%t" --tl "%g" --ty "%y" --tn "%n" %s %d

'''--alt-preset standard''' --add-id3v2 --pad-id3v2 --ta "%a" --tt "%t" --tl "%g" --ty "%y" --tn "%n" %s %d

'''APEv2: (requires [http://www.saunalahti.fi/cse/files/wapet.zip wapet.exe])'''
* Set file extension to .mp3
* Locate '''wapet.exe'''
%d -t "Artist=%a" -t "Title=%t" -t "Album=%g" -t "Year=%y" -t "Track=%n" -t "Genre=%m" lame.exe '''--alt-preset standard''' %s %d

'''Note 1:''' lame.exe needs to be in the same directory as wapet.exe.

'''Note 2:''' If you wanted to change the [[LAME#Encoder_Presets| Lame preset]], the green portion what you would substitute with the new preset.

'''Note 3:''' If you are using Lame version 3.95.1+, please note that '''--alt-preset''' is no longer used, it is now just '''--preset'''

'''Note 4:''' The '''%l...%l''' and '''%h...%h''' placeholders are used to add text according to whether the High quality or Low quality radio button is selected as shown below:

'''%l--alt-preset 128%l%h--alt-preset standard%h''' %s %d

Therefore, if you select '''Low quality''', EAC will invoke the LAME encoder with the following command line parameters:

LAME.EXE --alt-preset 128 %s %d

..and if you select '''High quality''' EAC will invoke LAME with these command line parameters:

LAME.EXE --alt-preset standard %s %d

You can access the bitrate value in the dropdown list using the '''%r''' placeholder, For Example:

--alt-preset %r %s %d

So, if you selected '''192 kBit/s''' in the '''Bit Rate''' drop-down list, the command line would be:

LAME.EXE --alt-preset 192 %s %d

It is a generally accepted fact that the bitrate selected in the drop-down list doesn't affect the command line. In essence this is true, as it will not affect the command line ''unless you use the %r placeholder''. However, using ABR or CBR over VBR is not recommended and hence, you will probably never have to use the '''%r''' option.

Monkey's Audio

2005-07-06T03:45:38Z

A Man Eating Duck: added EAC and Monkey's Audio compression guide

=Introduction=
Monkey's Audio (APE) is a free [[lossless]] audio compression format with a highly competitive compression algorithm, and is used primarily by Windows users. Although software is available for Linux, Monkey's Audio is not as popular among this operating system's users. Monkey's Audio suffers from slow decompression speeds as compared to other lossless audio codecs.

Monkey's Audio uses a combination of traditional lossless compression tactics ([[linear prediction]] and [[channel coupling]]) and a simple [[Neural network]]. To store the output values of its prediction step it uses [[Range coding]], modified to work well with more or less continuous values.

Monkey's Audio's main competitor is [[FLAC]], which has more features than Monkey's Audio (streaming support, for example) and hardware support to its advantage, though its efficiency in compression is not as great.

Monkey's Audio is released under a "custom" license that allows you to do pretty much anything with the source code, on the provision that you ask the author for permission.

Exact Audio Copy

A Man Eating Duck: /* Exact Audio Copy Guides */

[http://www.exactaudiocopy.org Exact Audio Copy] (EAC for short) is a free software that can be used to extract tracks from an Audio CD to your computer's hard disk. What makes EAC special compared to other rippers is the fact that it is capable of reading audio CDs almost perfectly.
EAC uses various methods for extracting audio data. EAC can also invoke externally installed encoders, thereby making it possible to simultaneously rip and encode audio data to the format of your choice.

=Features of Exact Audio Copy=
* Usage of the Windows 95 and Windows NT ASPI Interface, so both SCSI and ATAPI CD-ROM drives are supported
* Hidden sector synchronization (jitter correction)
* Secure, fast and burst extraction methods selectable. Fast extraction should run at the same speed as other grabbers, but is probably not exact anymore. Burst mode just grabs the audio data without any synchronization.
* Read error and complete loss of sync detection and correction in secure modes, as far as possible
* Output of time positions of all non-exact corrections and listen to these positions
* Copy of ranges of music data, not only tracks
* Automatic Speed reduction on errors and fallback afterwards
* Normalization of extracted audio
* Usage of the Windows Audio Compression Manager (ACM Codecs) for direct compression e.g. to MP3 waves
* Support for the BladeEnc DLL that is usable like an ACM Codec for online MP3 compression
* Support of external MP3, VQF, RA and AAC encoders for automatic compression after extraction
* Batch compression and decompression of/to WAV files
* Compression offset support for exact compression/decompression
* Detection of pre-track gaps
* Detection of silence in pre-track gaps
* Automatic creation of CUE sheets for CDRWin, including all gaps, indicies, track attributes, UPC and ISRC
* CD player functionality and prelistening to selected ranges
* Automatic detection of drive features, whether a drive has an accurate stream and/or does caching
* Sample Offsets for drives with no accurate streams, including the option of filling up missing samples with silence
* Option for synchronizing tracks for non-accurate stream drives
* Filename editing with local and remote CDDB database and cdplayer.ini support and more features like ID3 tagging
* Browse and edit local database
* Local CDDB support
* Record and Loop Record functions for recording from LP, radio, etc.
* Automatic rename of MP3 files according to their ID3 tag
* Catalog extraction function
* Multisession (CD-Extra) support
* CD-Text support
* CD-Write support for some drives
* ID3 Tag editor with drag and drop possibility from track listing and database
* Glitch removal after extraction
* Small WAV editor with the following functionality: delete, trim, normalize, pad, glitch removal, pop detection, interpolation of ranges, noise reduction, fade in/out, undo (and more)
* Program is Cardware, so feel free to copy

=Exact Audio Copy Guides=
You can begin configuring EAC by starting with the Drive Configuration followed by the Gap Settings and finally, the Encoder Options. Remember to use only an original, factory-pressed Audio CD for configuring EAC. Please do not use, CD-Rs, CD-RWs, bootlegs or any such discs. Also use a non copy-protected disc which carries the familiar "Compact Disc-Digital Audio" logo.

A Man Eating Duck: added link to Rjamorim's lossless comparison

'''TTA''' (True Audio) audio codec is a free, simple real-time [[lossless]] audio encoder/decoder, based on adaptive prognostic filters which has shown satisfactory results comparing to majority of modern analogs.

==TTA Compressor==

* Down to 30-60% [[lossless]] audio data compression
* Real-time encoding/decoding algorithm
* Fast decoding and encoding
* Multiplatform
* Open source code and documentation
* Hardware support

TTA performs [[lossless]] compression on multichannel 8, 16 and 24 bit data of the [[WAV]] audio files. Being "lossless" means that no data/quality is lost in the compression - when uncompressed, the data will be identical to the original. The compression ratios of TTA depend on the type of music file being compressed, but the compression size will generally range between 30% - 70% of the original. TTA format supports both [[ID3]]v1 and [[ID3]]v2 information tags.

==The Project==

The TTA project provides:

* Free and simple data format
* Plugins for the most popular media players
* TTA DirectShow filters
* Tau Producer - GUI based compressor for Windows
* Set of the C/C++ TTA development libraries

Shorten

A Man Eating Duck: added link to Rjamorim's lossless comparison

Shorten is one of the oldest [[Lossless]] audio formats. It was creader by Tony Robinson in the mid-nineties.

It lacks several features like seekability (although there is a "hack" that adds seek support), [[Streaming|streamability]], support for [[Multichannel]] and high [[Sampling rate|sampling rates]], tagging...

The reason why it became very popular is that it was the first open source lossless compressor. It gained huge momentum years ago because of it, and to this day it's the most popular format for lossless audio encoding, being used mostly at live recordings (bootlegs) trading communities.
