Core Audio File file type
What is a *.caf file?
The Core Audio Format (CAF) was created in 2005 by Apple and is a container for storing high quality audio. It is compatible with all macOSX 10.4 and higher operating systems. It is often seen as an improvement to the AIF, AIFF, and WAV file formats namely by exceeding the 4GB file size limit of those older formats. It uses 64-bit offsets to accomplish this. A CAF container is similar to the QuickTime .MOV container file; they both can contain many different audio formats, metadata tracks, and much more metadata including (creator, track length, file name, album, composer, and more). CAF files are primarily used by Soundtrack Pro and Logic Studio for loops and audio effects. When used with the Apple Lossless codec, surround sound audio clips are stored in CAF files.
