Audio file format
open-in-new
<p>An audio file format is a <a href="/facts/File_format/qrXbwJaH">file format</a> for storing <a href="/facts/Digital_audio/PgugcLAI">digital audio</a> data on a <a href="/facts/Computer/SQe1aK05">computer</a> system. The bit layout of the audio data (excluding <a href="/facts/Metadata/qt35z79C">metadata</a>) is called the <a href="/facts/Audio_coding_format/qHAhppfD">audio coding format</a> and can be uncompressed, or <a href="/facts/Audio_compression_(data)/gMFuY4FT">compressed</a> to reduce the file size, often using <a href="/facts/Lossy_compression/jHW7DDv3">lossy compression</a>. The data can be a raw <a href="/facts/Bitstream/Pf9oGYyY">bitstream</a> in an audio coding format, but it is usually embedded in a <a href="/facts/Container_format/mSfwwdSA">container format</a> or an audio data format with defined storage layer. </p>
