 - AIFF (Audio Interchange File Format) is one of the two most-used 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."
The extension for this file type is ".aif" when it is used on a PC. 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. For example, a file could retain
information about selected regions of the audio data used for recalling
zoom levels not used by other applications.
