Lossless compression

losslesslossless data compressioncompression
Monkey's Audio is an algorithm and file format for lossless audio data compression. Lossless data compression does not discard data during the process of encoding, unlike lossy compression methods such as AAC, MP3, Vorbis and Musepack.

Rockbox

Rockbox ProjectRockbox kernelRockbox port
Monkey's Audio main drawbacks are the fact that it employs a symmetric algorithm, meaning the decoding takes comparable resources to encoding, which makes it unsuitable for all but the fastest portable players (via Rockbox firmware), and that it has limited support on software platforms other than Windows; on other platforms only decoding is officially supported by third-party programs.

Shorten (file format)

ShortenSHN.shn
The Shorten format, popular with live taping enthusiasts for years, is no longer in development, but is still in use on some sites such as etree.
Shorten is no longer developed and other lossless audio codecs such as FLAC, Monkey's Audio (APE), TTA, and WavPack (WV) have become more popular.

Apple Lossless

ALACApple Lossless Audio Codec.m4a
Similar to the FLAC and Apple Lossless format, files encoded to Monkey's Audio are typically reduced to about half of the original size, with data transfer rates and bandwidth requirements being reduced accordingly.

WavPack

Monkey's Audio's advantages are better compression rates compared to FLAC and WavPack, as well as multithreading/multicore support.

FiiO X Series

Monkey's Audio is supported natively on all modern Cowon multimedia media players, the FiiO X Series and some Cayin digital audio players.

APE tag
