WHAT IS AIF?
Audio Interchange File Format
Apple created AIF in 1988, based on EA’s Interchange File Format. The AIF file type is mostly used in the macOS and iOS operating systems and in iTunes. However, VLC and other players that are not native Mac tools can open AIFs too. If you need more detailed information about how to play an AIF file, check the list of associated programs below.
According to the published specifications, AIF format files store raw uncompressed audio, which takes a lot of storage space. A standard AIF file has a sampling rate of 44.1KHz and a bit depth of 16 bits. Structurally, AIFs are divided into chunks. Each chunk stores a different type of information: the actual audio data necessary for playback, the track name, metadata, etc.
