When audio from an audio CD is imported by dragging to the macOS Desktop, the resulting file is also an AIFF-C/sowt. When a file is imported to or exported from iTunes in "AIFF" format, it is actually AIFF-C/sowt that is being used. Īpple uses this new little-endian AIFF type as its standard on macOS. The only difference between a standard AIFF file and an AIFF-C/sowt file is the byte order there is no compression involved at all. īecause the AIFF architecture has no provision for alternative byte order, Apple used the existing AIFF-C compression architecture, and created a "pseudo-compressed" codec called sowt ( twos spelled backwards). With the development of the OS X operating system now known as macOS, Apple created a new type of AIFF which is, in effect, an alternative little-endian byte order format.

This section possibly contains original research. aif are accepted as well by audio applications supporting the format. For the compressed variants it is supposed to be. The file extension for the standard AIFF format is. In addition to audio data, AIFF can include loop point data and the musical note of a sample, for use by hardware samplers and musical applications. There is also a compressed variant of AIFF known as AIFF-C or AIFC, with various defined compression codecs. This type of AIFF file uses much more disk space than lossy formats like MP3-about 10 MB for one minute of stereo audio at a sample rate of 44.1 kHz and a bit depth of 16 bits. ![]() The audio data in most AIFF files is uncompressed pulse-code modulation (PCM). in 1988 based on Electronic Arts' Interchange File Format (IFF, widely used on Amiga systems) and is most commonly used on Apple Macintosh computer systems. AIFF-C / July 1991 31 years ago ( 1991-07) Īudio Interchange File Format ( AIFF) is an audio file format standard used for storing sound data for personal computers and other electronic audio devices.
