Source format: FLAC

FLAC stands for Free Lossless Audio Codec. It is a widely used audio format for storing music and other recordings without losing any original audio data during compression. FLAC is popular with audiophiles, music libraries, archivists, podcasters, and anyone who wants smaller files than WAV or AIFF while preserving full quality. Typical uses include music archiving, high-quality playback, and distribution of lossless audio.

Target format: CAF

CAF means Core Audio Format, an Apple-designed container for audio data. It is commonly used on macOS and iOS for professional audio, editing, and large or long-duration recordings. CAF supports very large files, flexible metadata, and a variety of audio encodings. Its main advantages are Apple ecosystem compatibility, scalability for long recordings, and suitability for audio production workflows.

How to perform the conversion

The most reliable desktop tool for FLAC to CAF conversion is FFmpeg, because it can decode FLAC and write CAF while preserving the audio data when the chosen CAF codec is lossless or uncompressed.

  1. Install FFmpeg on your computer.
  2. Open a terminal or command prompt.
  3. Run a command such as ffmpeg -i input.flac -c:a pcm_s16le output.caf to create a CAF file with uncompressed 16-bit PCM audio.
  4. If your source FLAC is 24-bit or you want to preserve higher precision, use a matching PCM codec such as ffmpeg -i input.flac -c:a pcm_s24le output.caf.
  5. Check the resulting file in an Apple audio app or another CAF-compatible player/editor.

If you prefer a graphical workflow, use an audio editor that supports both formats, such as Audacity with FFmpeg support or a professional Apple-compatible editor. Open the FLAC file, then choose File → Export or File → Save As, and select CAF if the application offers it. Not all editors can write CAF, so FFmpeg is usually the safest choice.

Notes on quality, compatibility, or limitations

FLAC is lossless, so the conversion can preserve audio quality only if the CAF output uses a lossless or uncompressed codec. If you convert FLAC to a compressed lossy codec inside CAF, quality will be reduced. Also, CAF is less universally supported than FLAC; it is best suited for Apple software and professional audio tools rather than general playback on every device.

Metadata support may vary by application. Album art, tags, and chapter markers from FLAC may not transfer perfectly into CAF depending on the converter. For archival purposes, keep the original FLAC file as the master copy and use CAF for editing or Apple-centric workflows.
