Audio Interchange File Format

Uncompressed audio formats, such as WAV, AIFF, AU or raw header-less PCM;
Audio Interchange File Format (AIFF) is an audio file format standard used for storing sound data for personal computers and other electronic audio devices.

Au file format

AU.au.au format
Uncompressed audio formats, such as WAV, AIFF, AU or raw header-less PCM;
The Au file format is a simple audio file format introduced by Sun Microsystems.

Digital container format

container formatcontainercontainer formats
The data can be a raw bitstream in an audio coding format, but it is usually embedded in a container format or an audio data format with defined storage layer. It is important to distinguish between the audio coding format, the container containing the raw audio data, and an audio codec.
Since audio and video streams can be coded and decoded with many different algorithms, a container format may be used to provide a single file format to the user.

Raw audio format

RAW
Uncompressed audio formats, such as WAV, AIFF, AU or raw header-less PCM;
RAW Audio format or just RAW Audio is an audio file format for storing uncompressed audio in raw form.

Audio coding format

audio coding standardaudio compression formatAudio coding
The bit layout of the audio data (excluding metadata) is called the audio coding format and can be uncompressed, or compressed to reduce the file size, often using lossy compression. It is important to distinguish between the audio coding format, the container containing the raw audio data, and an audio codec.
As such, the user normally doesn't have a raw AAC file, but instead has a .m4a audio file, which is a MPEG-4 Part 14 container containing AAC-encoded audio.

Data compression

compressionvideo compressioncompressed
The bit layout of the audio data (excluding metadata) is called the audio coding format and can be uncompressed, or compressed to reduce the file size, often using lossy compression.
Some audio formats feature a combination of a lossy format and a lossless correction; this allows stripping the correction to easily obtain a lossy file.

Metadata

meta datameta-datacommunications metadata
WAV and AIFF are designed to store a wide variety of audio formats, lossless and lossy; they just add a small, metadata-containing header before the audio data to declare the format of the audio data, such as LPCM with a particular sample rate, bit depth, endianness and number of channels.
There are different metadata standards for each different discipline (e.g., museum collections, digital audio files, websites, etc.).

Compact Disc Digital Audio

Audio CDCDRed Book
One major uncompressed audio format, LPCM, is the same variety of PCM as used in Compact Disc Digital Audio and is the format most commonly accepted by low level audio APIs and D/A converter hardware.
Common audio file formats for this purpose include WAV and AIFF, which simply preface the LPCM data with a short header; FLAC, ALAC, and Windows Media Audio Lossless, which compress the LPCM data in ways that conserve space yet allow it to be restored without any changes; and various lossy, perceptual coding formats like MP3 and AAC, which modify and compress the audio data in ways that irreversibly change the audio, but that exploit features of human hearing to make the changes difficult to discern.

Formats with lossy compression, such as Opus, MP3, Vorbis, Musepack, AAC, ATRAC and Windows Media Audio Lossy (WMA lossy).

The term is applied to both the physical recording media and the recording formats of the audio content—in computer science it is often limited to the audio file format, but its wider use usually refers to the physical method used to store the data.

Audio codec

It is important to distinguish between the audio coding format, the container containing the raw audio data, and an audio codec. Although most audio file formats support only one type of audio coding data (created with an audio coder), a multimedia container format (as Matroska or AVI) may support multiple types of audio and video data.
