Overview

AIFF (Audio Interchange File Format) files store uncompressed signed audio samples inside an IFF container. See that article for more details. There's also a compressed variant, called AIFC, which has its own page.

AIFF chunks provide native metadata. In addition, although it is not in the specification, an ID3 chunk is often used to include ID3V2 metadata.
