AIFF file extension icon

AIFF is a file extension for the Audio Interchange File Format. An AIFF file is a sound format used by Silicon Graphics and Macintosh applications

AIFF is one of the two most common audio file formats used in the Apple Macintosh operating system. The other is Sound Designer II (SDII). Most CD writers can accept AIFF or SDII files interchangeably when writing a Red Book audio CD. AIFF is sometimes referred to as "Apple Interchange File Format."

In Windows the extension for this file type is ".aif". On a Mac, the file extension is not needed. A Mac file uses a Type and Creator resource to identify itself to the operating system and the applications that can open it.

An AIFF file contains the raw audio data, channel information (monophonic or stereophonic), bit depth, sample rate, and application-specific data areas. The application-specific data areas let different applications add information to the file header that remains there even if the file is opened and processed by another application.

MIME type:  audio/aiff, audio/x-aiff, sound/aiff, audio/rmf, audio/x-rmf, audio/x-pn-aiff, audio/x-gsm, audio/mid, audio/x-midi, audio/vnd.qcelp
