An audio file format is a file format for storing digital audio data on a computer system. 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. 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.
Photopea. When you convert a file from a lossless format to a lossy format—say, ripping an audio CD (a lossless format) to MP3 files (a lossy format)—you're throwing away some of the data. The MP3 file is so much smaller because much of the original audio data has been lost. https://pottxf.over-blog.com/2021/01/taskdeck-1-1-3.html.
Format types[edit]
It is important to distinguish between the audio coding format, the container containing the raw audio data, and an audio codec. A codec performs the encoding and decoding of the raw audio data while this encoded data is (usually) stored in a container file. 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.
There are three major groups of audio file formats:
- Uncompressed audio formats, such as WAV, AIFF, AU or raw header-less PCM;
- Formats with lossless compression, such as FLAC, Monkey's Audio (filename extension
.ape), WavPack (filename extension.wv), TTA, ATRAC Advanced Lossless, ALAC (filename extension.m4a), MPEG-4 SLS, MPEG-4 ALS, MPEG-4 DST, Windows Media Audio Lossless (WMA Lossless), and Shorten (SHN). - Formats with lossy compression, such as Opus, MP3, Vorbis, Musepack, AAC, ATRAC and Windows Media Audio Lossy (WMA lossy).
Uncompressed audio format[edit]
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. Although LPCM can be stored on a computer as a raw audio format, it is usually stored in a .wav file on Windows or in a .aiff file on macOS. The Audio Interchange File Format (AIFF) format is based on the Interchange File Format (IFF), and the WAV format is based on the similar Resource Interchange File Format (RIFF). 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. Blocs 3 0 7 – visual web design tool tutorial. Since WAV and AIFF are widely supported and can store LPCM, they are suitable file formats for storing and archiving an original recording.
BWF (Broadcast Wave Format) is a standard audio format created by the European Broadcasting Union as a successor to WAV. Among other enhancements, BWF allows more robust metadata to be stored in the file. See European Broadcasting Union: Specification of the Broadcast Wave Format (EBU Technical document 3285, July 1997). This is the primary recording format used in many professional audio workstations in the television and film industry. BWF files include a standardized timestamp reference which allows for easy synchronization with a separate picture element. Stand-alone, file based, multi-track recorders from AETA,[1] Sound Devices,[2] Zaxcom,[3] HHB Communications Ltd,[4]Fostex, Nagra, Aaton,[5] and TASCAM all use BWF as their preferred format.
Lossless compressed audio format[edit]
A lossless compressed audio format stores data in less space without losing any information. The original, uncompressed data can be recreated from the compressed version.
Uncompressed audio formats encode both sound and silence with the same number of bits per unit of time. Encoding an uncompressed minute of absolute silence produces a file of the same size as encoding an uncompressed minute of music. In a lossless compressed format, however, the music would occupy a smaller file than an uncompressed format and the silence would take up almost no space at all.
Lossless compression formats include the common[6]FLAC, WavPack, Monkey's Audio, ALAC (Apple Lossless). They provide a compression ratio of about 2:1 (i.e. their files take up half the space of PCM). Development in lossless compression formats aims to reduce processing time while maintaining a good compression ratio.
Lossy compressed audio format[edit]
Lossy audio format enables even greater reductions in file size by removing some of the audio information and simplifying the data. This, of course, results in a reduction in audio quality, but a variety of techniques are used, mainly by exploiting psychoacoustics, to remove the parts of the sound that have the least effect on perceived quality, and to minimize the amount of audible noise added during the process. The popular MP3 format is probably the best-known example, but the AAC format found on the iTunes Music Store is also common. Most formats offer a range of degrees of compression, generally measured in bit rate. The lower the rate, the smaller the file and the more significant the quality loss.
List of formats[edit]
| File Extension | Creation Company | Description |
|---|---|---|
.3gp | Multimedia container format can contain proprietary formats as AMR, AMR-WB or AMR-WB+, but also some open formats | |
.aa | Audible (Amazon.com) | A low-bitrate audiobook container format with DRM, containing audio encoded as either MP3 or the ACELP speech codec. |
.aac | The Advanced Audio Coding format is based on the MPEG-2 and MPEG-4 standards. AAC files are usually ADTS or ADIF containers. | |
.aax | Audible (Amazon.com) | An Audiobook format, which is a variable-bitrate (allowing high quality) M4B file encrypted with DRM. MPB contains AAC or ALAC encoded audio in an MPEG-4 container. (More details below.) |
.act | ACT is a lossy ADPCM 8 kbit/s compressed audio format recorded by most Chinese MP3 and MP4 players with a recording function, and voice recorders | |

.flac | A file format for the Free Lossless Audio Codec, an open-source lossless compression codec. | |

.m4b | An Audiobook / podcast extension with AAC or ALAC encoded audio in an MPEG-4 container. Both M4A and M4B formats can contain metadata including chapter markers, images, and hyperlinks, but M4B allows 'bookmarks' (remembering the last listening spot), whereas M4A does not.[7] | |
.m4p | Apple | A version of AAC with proprietary Digital Rights Management developed by Apple for use in music downloaded from their iTunes Music Store. |
.mmf | Yamaha, Samsung | A Samsung audio format that is used in ringtones. Developed by Yamaha (SMAF stands for 'Synthetic music Mobile Application Format', and is a multimedia data format invented by the Yamaha Corporation, .mmf file format). |

.rf64 | One successor to the Wav format, overcoming the 4GiB size limitation. | |
.sln | Signed Linear PCM format used by Asterisk. Prior to v.10 the standard formats were 16-bit Signed Linear PCM sampled at 8 kHz and at 16 kHz. With v.10 many more sampling rates were added.[8] | |
.tta | The True Audio, real-time lossless audio codec. | |
.voc | Creative Technology | The file format consists of a 26-byte header and a series of subsequent data blocks containing the audio information |
.vox | The vox format most commonly uses the Dialogic ADPCM (Adaptive Differential Pulse Code Modulation) codec. Similar to other ADPCM formats, it compresses to 4-bits. Vox format files are similar to wave files except that the vox files contain no information about the file itself so the codec sample rate and number of channels must first be specified in order to play a vox file. | |
.wav | Standard audio file container format used mainly in Windows PCs. Commonly used for storing uncompressed (PCM), CD-quality sound files, which means that they can be large in size—around 10 MB per minute.
