Audio file icons of various formats. 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.
Audio in WAV files can be encoded in a variety of audio coding formats, such as GSM or MP3, to reduce the file size. All WAV files, even those that use MP3 compression, use the .wav extension. This is a reference to compare the monophonic (not stereophonic) audio quality and compression bitrates of audio coding formats available for WAV files ...
This metadata is stored as extension chunks in a standard digital audio WAV file. BWF is the recommended format for digitizing sound files by the International Association of Sound and Audiovisual Archives. [1] Files conforming to the Broadcast Wave specification have names ending with the filename extension.WAV.
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. The container also contains metadata such as title and other tags, and perhaps an index for fast seeking. [2] A notable exception is MP3 files, which are raw audio coding without a ...
Exact Audio Copy (EAC) is a CD ripping program for Microsoft Windows. The program has been developed by Andre Wiethoff since 1998. The program has been developed by Andre Wiethoff since 1998. Wiethoff's motivation for creating the program was that other such software only performed jitter correction while scratched CDs often produced distortion.

An audio format is a medium for sound recording and reproduction.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.
The first 4 bytes of the file are then changed from 'RIFF' to 'RF64'. RF64 files define the following extra chunks: "RF64" replaces "RIFF" chunk identifier of BWF/WAV formats; ds64, data size 64, first chunk under RF64; JUNK, a placeholder for ds64; An RF64 file with a 'bext' chunk becomes an MBWF-file. 'bext' is defined in BWF (ITU-R BS.1352-3).
