What Is CAF?
CAF (Core Audio Format) is Apple's professional audio container, designed for macOS and iOS audio development. It was created to overcome limitations of older formats:
- No file size limit — unlike WAV's 4GB cap, CAF supports unlimited file sizes
- Multiple audio streams — can store several audio channels in one file
- Rich metadata — text annotations, markers, channel layouts
- Multiple codecs — supports PCM, AAC, ALAC, Apple IMA, and more
CAF files come from:
- Logic Pro and GarageBand — Apple's music production tools
- iOS app development — sound assets for iPhone/iPad apps
- macOS system audio — system sounds and alerts
- Professional recording — long-duration studio sessions
Competitors like runconvert.com explains "CAF is natively supported within the Apple ecosystem (QuickTime, Logic Pro, GarageBand)" but "on Windows and Linux, native support is nonexistent — users must rely on VLC or Audacity." ahaconvert.com notes CAF "supports unlimited file sizes, multiple audio formats, and extensive metadata." soconvert.com processes entirely in-browser.
