Why Convert CAF to AIFF?
CAF (Core Audio Format) is Apple's modern audio container, designed to overcome the 4 GB file size limit of AIFF and WAV. It supports any audio codec, text annotations, markers, and channel layouts. However, CAF is primarily supported within the Apple ecosystem — Logic Pro, GarageBand, Final Cut Pro — and has limited compatibility on Windows and Linux. AIFF (Audio Interchange File Format) is Apple's older uncompressed audio format that is universally supported by every DAW, audio editor, and media player on all platforms.
CAF vs AIFF
| Feature | CAF (Core Audio) | AIFF (output) |
|---|---|---|
| Developer | Apple | Apple |
| Max file size | No limit (64-bit) | 4 GB (32-bit header) |
| Audio codecs | Any (AAC, ALAC, PCM, etc.) | PCM (uncompressed) |
| Markers & annotations | ✅ | Limited |
| Windows support | ❌ (VLC only) | ✅ (most players) |
| DAW compatibility | Logic Pro, GarageBand | ✅ Universal (all DAWs) |
| Pro Tools support | Limited | ✅ Native |
Use Cases
- Cross-platform editing — Convert CAF files from Logic Pro or GarageBand to AIFF for editing in Pro Tools, Audacity, Adobe Audition, or any DAW on Windows/Linux.
- Sample library creation — AIFF is a standard format for audio sample libraries. Convert CAF recordings to AIFF for distribution.
- Windows playback — Windows cannot play CAF natively. AIFF plays in most Windows media players and audio editors.
- Audio archival — AIFF stores uncompressed PCM audio, making it suitable for long-term archival of recordings originally captured in CAF.
What is CAF?
CAF (Core Audio Format) is Apple's audio container format, introduced in macOS 10.4. It has no file size limit (unlike AIFF's 4 GB cap), supports any audio codec, and can store metadata like markers, annotations, and channel layouts. It is primarily used by Logic Pro and GarageBand.
Will converting CAF to AIFF lose quality?
If the CAF file contains uncompressed PCM audio, the conversion is lossless — no quality is lost. If the CAF contains compressed audio (AAC, ALAC), it is decoded to uncompressed PCM in the AIFF output.
Can I play AIFF files on Windows?
Yes. AIFF is supported by VLC, Windows Media Player (with codec), iTunes for Windows, and most audio editing software. It has much broader Windows support than CAF.
What sample rate should I use?
Leave it set to "Original" to match the source file. Only change if your target application requires a specific rate (e.g., 48000 Hz for video production, 44100 Hz for CD audio).
Can I trim the audio during conversion?
Yes. Use the Trim option to set a start time and duration in seconds or HH:MM:SS.sss. Only the selected segment is converted.
