WavPack compression can compress (and losslessly restore) 8, 16, 24, and 32-bit fixed-point, and 32-bit floating-point PCM audio files in the .WAV file format. It can also handle DSD input in DSDIFF or DSF format. [2] It also supports surround sound streams and high sampling rates. Like other lossless compression schemes, the data reduction ...
The data compression software for encoding into ALAC files, Apple Lossless Encoder, was introduced into the Mac OS X Core Audio framework on April 28, 2004, together with the QuickTime 6.5.1 update, thus making it available in iTunes since version 4.5 and above, and its replacement, the Music application.

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 Advanced Audio Coding, MP3, Vorbis, and Opus. Therefore, it may be decompressed to a file that is identical to the source material.
Vorbis is a free and open-source software project headed by the Xiph.Org Foundation. The project produces an audio coding format and software reference encoder/decoder for lossy audio compression, libvorbis. [10] Vorbis is most commonly used in conjunction with the Ogg container format [11] and it is therefore often referred to as Ogg Vorbis.
Xiph.org is home to other free compression formats such as Vorbis, Theora, Speex and Opus. [5] [6] [7] Version 1.3.0 was released on 26 May 2013, at which point development was moved to the Xiph.org git repository. [8] In 2019, FLAC was proposed as an IETF standard, [9] and was published in December 2024 as RFC 9639.
Advanced Audio Coding (AAC) using libav for Windows and Linux or using CoreAudio in macOS; HE-AAC (till version 0.10.3 for Windows and Linux), using CoreAudio on macOS; AC-3; FLAC 16-bit and 24-bit; MPEG-1 or MPEG-2 Audio Layer III (MP3) Opus [17] Vorbis; TrueHD; Apple Lossless Audio Codec (ALAC) 16-bit and 24-bit
A lossless audio coding format reduces the total data needed to represent a sound but can be de-coded to its original, uncompressed form. A lossy audio coding format additionally reduces the bit resolution of the sound on top of compression, which results in far less data at the cost of irretrievably lost information.
The Meridian Lossless Packing logo The Advanced Resolution logo. Meridian Lossless Packing, also known as Packed PCM (PPCM), [citation needed] is a lossless compression technique for PCM audio data developed by Meridian Audio, Ltd. MLP is the standard lossless compression method for DVD-Audio content [1] (often advertised with the Advanced Resolution logo) and typically provides about 1.5:1 ...
