File extension details and usage information
The Core Audio Format (CAF) is a highly flexible and advanced digital audio container format developed by Apple Inc. It was specifically designed to overcome the limitations of older, legacy audio formats such as WAV and AIFF. One of its primary advantages is the use of 64-bit file offsets, which eliminates the 4 GB file size limit inherent to 32-bit formats, allowing for practically unlimited recording times (up to hundreds of years of audio). CAF is highly versatile, capable of containing many different audio compression formats, metadata, and channel layouts. It supports high channel counts, high sample rates, and can store auxiliary data like text captions, markers, and channel layouts. It is widely used in macOS and iOS environments, particularly within professional audio applications like Logic Pro and GarageBand, as well as for system sounds and game audio development.
