Short for Audio Interchange File Format, a common format for storing and transmitting sampled sound. The format was developed by Apple Computer and is the standard audio format for Macintosh computers. It is also used by Silicon Graphics Incorporated (SGI).
The AIFF format is uncompressed so AIFF files tend to be large. However, there is another format called AIFF-Compressed (AIFF-C or AIFC) that supports compression ratios as high as 6:1.
AIFF files generally end with an .AIF or .IEF extension.
AIFC files generally end with an .AIFC extension.
AIFF and AIFC are standard audio format used on MacOS systems. AIFF is not compressed. AIFC is compressed.
