Perl Audio Converter (PAC) is a tool for converting multiple audio types
from one format to another. It supports MP2, MP3, Ogg Vorbis, FLAC,
Shorten, Monkey Audio, FAAC (AAC/M4A/MP4), Musepack (MPC), Wavpack (WV),
OptimFrog (OFR/OFS), TTA, LPAC, Kexis (KXS), AIFF, AC3, Lossless Audio
(LA), BONK, AU, SND, RAW, VOC, SMP, RealAudio (RA/RAM), WAV, and WMA. It
can also convert audio from the following video formats/extensions: RM,
RV, ASF, DivX, MPG, MKV, MPEG, AVI, MOV, OGM, QT, VCD, VOB, and WMV. A
CD ripping function with CDDB support, batch and playlist conversion,
tag preservation for most supported formats, independent tag reading/
writing, and extensions for Konqueror and Amarok are also provided.

OptimFROG is a lossless audio compression program. Its main goal is to
reduce at maximum the size of audio files, while permitting bit identical
restoration for all input. It is similar with the ZIP compression, but it
is highly specialized to compress audio data.
OptimFROG obtains asymptotically the best lossless audio compression
ratios. It has Windows, Linux, and Mac versions, fully featured input
plug-ins for the Windows Media Player, foobar2000, Winamp2/3/5, dBpowerAMP,
XMPlay, QCD, and XMMS audio players (with bitstream error resilience,
ID3v1.1 and APEv2 read tagging support, ID3v2 compatible), optimal support
for all integer PCM wave formats up to 32 bits and an extensible streamable
(error tolerant) compressed format. It is also fast, the default mode
encodes CD quality audio data at 12.4x real-time and decodes at 17.4x real-
time on AMD Athlon XP 1800+ (the fastest mode encodes at 28.1x real-time
and decodes at 24.7x real-time). Self-extracting (sfx) archives can also be
created with a small overhead of just 54 KB.

LPAC is a codec (coder / decoder) for lossless compression of digital audio
files. "Lossless" means that any compressed file can be decompressed in a way
it will be bit-wise identical with the original. This is the main advantage
of LPAC compared to lossy formats like MP3, WMA or RealAudio. On the other
hand, lossy codecs can achieve higher compression ratios. For example, MP3 at
128 kbit/s achieves a (fixed) compression ratio of 11, whereas LPAC's
compression ratios range from 1.5 to 4, strongly depending on the audio
material. Typically they are around 2 for pop music and 2.5 for classical
music. This may not seem much, but remember you will get back every single
bit, no matter how often you subsequently compress and decompress a file. It
is true that general archivers (Zip, LZH, gzip) are lossless, too, but they
often achieve nearly no compression on audio files.

Kexis - A lossless WAV file compressor. Kexis' main goal is to develop
prediction and encoding schemes to minimize compressed file size. Kexis
strives to be the premier lossless sound encoder.

This module returns a hash containing basic information about a
Musepack file, as well as tag information contained in the Musepack
file's APE tags. See Audio::APETags for more information about the
tags.

This module returns a hash containing basic information about a FLAC file,
a representation of the embedded cue sheet if one exists, as well as tag
information contained in the FLAC file's Vorbis tags. There is no complete
list of tag keys for Vorbis tags, as they can be defined by the user; the
basic set of tags used for FLAC files include:
* ALBUM
* ARTIST
* TITLE
* DATE
* GENRE
* TRACKNUMBER
* COMMENT
