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.

What is FLAC?

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

When Should You Use CAF vs FLAC?

CAF vs FLAC: Key Differences

• •CAF and FLAC 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.
• •How transparency is handled: FLAC supports transparency, so alpha information is preserved during conversion.
• •File sizes: CAF files typically range Flexible, supports very large files and FLAC files 5MB per minute at CD quality.
• •Use case fit: CAF targets apple audio production, professional editing and FLAC targets archival audio, audiophile listening — your choice depends on which workflow stage you are serving.

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.
• ✓The trade-off for CAF's perfection is larger files — but for archival work, it is worth every megabyte.
• ✓CAF is a first-class citizen in all major software ecosystems, from creative suites to development environments.

Advantages of FLAC

• ✓FLAC uses lossless compression tailored for Archival audio, audiophile listening.
• ✓FLAC is supported natively on virtually every device, browser, and operating system.
• ✓FLAC files are bit-for-bit perfect, preserving every pixel and sample for professional work.
• ✓FLAC integrates seamlessly with all major creative tools and workflows.
