About CAF to AMR Conversion
CAF is Apple's professional audio container with unlimited codec and file size support. AMR (Adaptive Multi-Rate) is ETSI's speech-optimized codec for mobile telephony. AMR-NB operates at 8 kHz mono (4.75-12.2 kbps), while AMR-WB reaches 16 kHz (up to 23.85 kbps).
Converting CAF to AMR takes professional macOS recordings and compresses them for telephony delivery. If the CAF contains PCM or ALAC, the AMR output benefits from lossless source quality.
Why Convert CAF to AMR?
CAF files cannot be processed by telephony infrastructure. Voicemail systems, IVR platforms, and MMS gateways require AMR or 3GP. Converting CAF to AMR enables macOS-recorded content to enter the mobile telephony pipeline.
This conversion is specifically useful for voice content recorded in professional macOS environments (Logic Pro, GarageBand) that must be deployed in telephony applications.
Common Use Cases
- Converting Logic Pro voice recordings for IVR telephone systems
- Preparing macOS-recorded audio for mobile voicemail deployment
- Compressing CAF voice memos for MMS delivery
