'''Audio Interchange File Format''' ('''AIFF''') is an [[audio file format]] standard used for storing [[sound]] data for [[personal computer]]s and other electronic audio devices. The format was developed by [[Apple Inc.|Apple Inc]]. in 1988 based on [[Electronic Arts]]' [[Interchange File Format]] (IFF, widely used on [[Amiga]] systems) and is most commonly used on [[Macintosh|Apple Macintosh]] computer systems.

The [[digital audio|audio data]] in most AIFF files is uncompressed [[pulse-code modulation]] (PCM). This type of AIFF file uses much more disk space than [[lossy]] formats like [[MP3]]—about 10&nbsp; MB for one minute of stereo audio at a sample rate of 44.1&nbsp;kHz and a bit depth of 16 bits. There is also a compressed variant of AIFF known as '''AIFF-C''' or '''AIFC''', with various defined compression codecs.

In addition to audio data, AIFF can include [[Loop (music)|loop]] point data and the musical note of a [[sampling (music)|sample]], for use by hardware samplers and musical applications.

The file extension for the standard AIFF format is <code>.aiff</code> or <code>.aif</code>. For the compressed variantsformat itthe ispreferred supposedsuffix to beis <code>.aifc</code>, but audio applications supporting the format also allow <code>.aiff</code> or <code>.aif</code> are accepted as well by audio applications supporting the format.
