Description

CAF stands for Core Audio Format, created by Apple in 2005. It’s a container format for storing digital audio. A number of audio-editing applications for iOS and macOS use this file type for their loop and sound effects library.

Technical details

According to Apple’s specification, CAF format uses 64-bit file offsets, allowing for almost limitless playback time. Older formats such as AIFF and WAV have a 4GB size limit, and this significantly reduces their playback time. CAF can also save recorded audio data without updating the data header’s size field. If the recording is interrupted, this feature may come in handy.
