Audio Formats
Main formats
AAC
Advanced audio coding
The format is a further development of the MP3 format.
A THE C
Apple lossless audio codec
Apple Lossless (also known as Apple Lossless Encoder, ALE or Apple Lossless Audio Codec, ALAC) is an audio codec developed by Apple Inc for lossless compression of digital music.
ALS
MPEG-4 audio lossless encoding
MPEG-4 ALS is an efficient and fast codec for a variety of applications.
AMR
Adaptive multiple rate
The AMR compression format was developed specifically for use in cellular systems. Its field of application is voice audio content compression.
BOW
Monkey Audio
Monkey’s Audio (Windows only) is considered one of the best lossless audio codecs for storing music due to its effective ratio of output file size to speed.
ATTRAC
Adaptive Transformation Acoustic Coding
ATRAC is a lossy compression system based on psychoacoustic principles. Compresses an audio CD to approximately 1/5 of the original with a slight loss in sound quality.
Asao
Nellymoser audio codec
Nellymoser Asao is a proprietary codec that was designed for low bit rates.
CELTIC
Overlapping Energy Constrained Transformation
The CELT codec is an algorithm for compressing audio data. Like MP3, Vorbis, and AAC, it is suitable for high-quality music streaming. Unlike these formats, CELT also has a very low latency, lower even than Speex, GSM or G.729.
Dolby
Dolby has developed many audio sound formats. Among them there are also compression formats.
FLAC
Free Lossless Audio Codec
FLAC is possibly the most popular lossless audio compression format.
LossyWAV
LossyWAV is a free lossy compression format. But, in essence, it is a preprocessor for PCM audio stored in WAV containers.
MP1
MPEG-1/2 Audio Layer I
MPEG-1 Audio Layer I (abbreviated as MP1) is one of the three formats included in the MPEG-1 standard. Even though it is compatible with many media players, the codec is already very outdated and has been superseded by the MP2 and MP3 codecs.
MP2
MPEG-1/2 Audio Layer II
MP2 is still used in the broadcasting industry for satellite transmission of digital video transmission and digital audio transmission.
MP3
Audio Layer III MPEG-1/2
The format is sometimes confused with MPEG-3, but MP3 is designed to compress only audio information and the full name sounds like MPEG Audio Layer-3.
MP3 surround sound
In 2004, Fraunhofer IIS released a backward compatible extension for MP3. MP3 Surround files provide high quality 5.1 sound with new decoders.
MP4
MPEG-4 Part 14
These are file extensions for the MPEG-4 container format, which can include all types of multimedia (video, natural and synthetic audio, 2D and 3D graphics, animated avatars, etc.).
MPC
Musepack
Musepack is a lossy compression scheme invented by the German programmer Andree Buschmann.
MT9
A new multitrack waveform data storage format that claims to be MP3.
Ogg Vorbis Audio
The Ogg vorbis format was developed by Xiphophorus. On the same site you can find the source codes of the project. It is part of the Ogg project to create a completely open multimedia system.
OptimFROG
OptimFROG is a lossless compression algorithm whose main goal is to reduce the size of audio files as much as possible. This is somewhat similar to ZIP compression, but is highly specialized for audio data.
Opus
Opus is a highly versatile, royalty-free, open source audio codec.
RealMedia
RealMedia is a proprietary streaming and multimedia file format owned by RealNetworks products and services.
SND
Sound
SND (SouND) is a digital audio file format created by Apple.
Speex
Speex is a patent-free audio compression format developed for voice transmission, as well as for use in open source software (eg VoIP).
TAK
Tom’s lossless Audio Kompressor
TAK is lossless audio compression that provides APE efficiency and FLAC decoding speed.
VQF
TwinVQ
A proprietary format that was created to replace MP3, but was never fully developed due to its proprietary nature.
Wav
Wave audio file format
The WAV format is perhaps the most common audio storage format. It is the easiest to use to process and is compatible with almost all audio players.
WMA
Windows Media Audio
WMA is a compression format developed by Microsoft.
WavPack
WavPack is a completely open, lossless, high quality, lossy audio compression format with a unique hybrid mode.
