What is a CAF file?
CAF is Apple's Core Audio container, made to remove the 4 GB limit of WAV and AIFF. Xcode projects, GarageBand loops and iOS apps use CAF for sound effects.
CAF is mainly used for iOS app sounds, GarageBand loops and long recordings. It plays on Macs, iPhones and QuickTime; Windows and Android need a converter.
