What is CAF Player?
The CAF Player lets you play Apple Core Audio Format files directly in your browser without installing any Apple software. CAF is used by iOS Voice Memos, GarageBand, and various macOS audio APIs. Playback runs locally using FFmpeg via WebAssembly, so your files stay private.
How does CAF Player work?
CAF (Core Audio Format) is Apple's proprietary audio container introduced in macOS 10.4. It is used by iOS Voice Memos, GarageBand, and internal macOS audio APIs. CAF has no support outside Apple software, making it difficult to play on Windows or Linux. This player uses FFmpeg compiled to WebAssembly to decode CAF in any browser.
