FLAC (Free Lossless Audio Codec) provides lossless compression of digital audio without any quality loss, reducing file size by 50-60%.

What is CAF?

Core Audio Format (CAF) is Apple's audio container designed to overcome the file size and sample rate limitations of AIFF and WAV.

When Should You Use FLAC vs CAF?

FLAC vs CAF: Key Differences

• •FLAC and CAF diverge on compression: lossless compression for the source, lossless compression for the target.
• •Both formats share lossless compression, so quality behavior is similar across the two — file size differences come from algorithm efficiency rather than compression philosophy.
• •Alpha channel support: CAF lacks transparency support.
• •File sizes: FLAC files typically range 5MB per minute at CD quality and CAF files Flexible, supports very large files.
• •FLAC is optimized for archival audio, audiophile listening while CAF is designed for apple audio production, professional editing — choose based on your specific workflow needs

Advantages of CAF

• ✓The lossless nature of CAF means file sizes stay reasonable while handling Apple audio production, professional editing efficiently.
• ✓From mobile devices to enterprise servers, CAF is recognized and supported everywhere.
