Audio Interchange File Format (AIFF) is an audio file format standard primarily used on Apple computers. It was originally developed in 1988 and was based on IFF which is an older format used for Amiga computers.
The audio data in a standard AIFF file is uncompressed pulse-code modulation (PCM). The files can also be compressed and are known as AIFF-C or simply AIFC using a lossless compression. The extension used is .aiff, .aif, or .aifc (compressed).
AIFF uses about 10MB for one minute of stereo audio at a sample rate of 44.1 kHz and a sample size of 16 bits. (CD quality)
