Preferred type is audio/aiff
Important: An officially mentioned type either does not exist, or is hard to track down. The information here likely reflects community contributions or popular usage derived from existing implementations.
AIFF (Audio Interchange File Format) files store uncompressed signed audio samples inside an IFF container. There's also a compressed variant, called AIFC with the same mimetype.
AIFF chunks provide native metadata. In addition, although it is not in the specification, an ID3 chunk is often used to include ID3V2 metadata.
It is difficult to trace down official mention of an official mimetype declaration, however you should follow existing guidance which is to assign with audio/aiff and support reading from audio/x-aiff also.
