What is a CAF file?

The Core Audio Format (CAF) is a container designed by Apple Inc. to overcome the 4 GB size limitation of legacy formats like AIFF and WAV. Introduced with Mac OS X 10.4, it uses 64-bit file offsets, allowing for massive data storage suitable for long-duration, high-resolution multi-channel recordings. The format is a wrapper that can contain various audio data types, including Linear PCM, Apple Lossless (ALAC), and AAC, organized into a chunk-based structure comprising a header, audio data chunk, and optional metadata chunks such as packet tables.

How to open a CAF file

CAF is natively supported within the Apple ecosystem, including macOS (QuickTime Player, Logic Pro, GarageBand) and iOS devices. On Windows and Linux, native support is nonexistent; users must rely on the VLC media player or Audacity (with FFmpeg libraries) to decode the container. Specialized audio engineering software such as GoldWave or Adobe Audition also handles CAF inputs.

What is a WAV file?

The Waveform Audio File Format (WAV) is a raw audio bitstream standard developed by Microsoft and IBM, serving as a subset of the Resource Interchange File Format (RIFF) specification. It primarily stores uncompressed Linear Pulse Code Modulation (LPCM) audio data, making it the industry standard for archival and high-fidelity mastering on Windows systems. The format supports varying bit depths and sample rates, with the Red Book standard (44.1 kHz, 16-bit stereo) being the most prevalent implementation.

How to open a WAV file

WAV files enjoy near-universal native support across all major operating systems due to their status as a foundational audio standard. Windows Media Player, Apple QuickTime, and Linux-based media players (via ALSA/PulseAudio) open WAV files by default without requiring external codec packs or third-party software.
