Frequently Asked Questions
What is CAF format?
CAF (Core Audio Format) is Apple's professional audio container format used in Logic Pro, GarageBand, Final Cut Pro, and iOS audio messages. It's a flexible container that can contain various codecs and supports high sample rates and multi-channel audio.
What is the difference between CBR and VBR?
CBR (Constant Bitrate) maintains the same bitrate throughout, resulting in predictable file sizes. VBR (Variable Bitrate) adjusts the bitrate based on audio complexity, often providing better quality at smaller file sizes.
Which mode should I use?
For most uses, VBR quality 2-4 provides excellent results with smaller file sizes. Use CBR for streaming or when you need predictable file sizes.
What bitrate is recommended?
192 kbps CBR or VBR quality 2 provides excellent quality for most listeners. 320 kbps CBR or VBR quality 0 is near-transparent quality. Lower settings (128 kbps) are suitable for podcasts or voice.
Will I lose quality converting from CAF?
CAF can contain various codecs - if it contains uncompressed audio, converting to MP3 will result in some quality loss. However, with good settings (192+ kbps or VBR Q2+) the difference is minimal for most listeners. The benefit is much smaller file sizes and universal compatibility.
