What is an CAF file?

The Core Audio Format (CAF) is an audio file format developed by Apple Inc. It is designed to overcome the limitations of older digital audio formats, including AIFF and WAV. CAF files are flexible and can store a variety of audio data with high-quality sound.

More Information.

The .CAF format was created to provide a comprehensive audio data storage solution, free from the size limitations of previous formats. It was designed to support files larger than 4 GB, an inherent limitation in older formats like WAV.

Origin Of This File.

The .CAF file format was introduced by Apple Inc. with the release of Mac OS X 10.4 (Tiger) in 2005. It was developed as part of Core Audio, Apple’s framework for handling digital audio in Mac OS X.

File Structure Technical Specification.

.CAF file consists of a series of chunks, each defined by a type code and size indicator. This structure allows it to hold various types of audio data, metadata, and even text annotations.

The format supports a wide range of audio formats, bit depths, and sample rates, making it highly versatile.
