CAF (Core Audio Format) is Apple's professional audio container, native to Logic Pro and macOS Core Audio. iPod Audio produces AAC in M4A optimized for iPod hardware — the iPod Classic's Wolfson/Cirrus Logic DAC includes dedicated AAC hardware decoders enabling 30+ hours of continuous playback.
Converting CAF to iPod Audio creates compact, hardware-decoded audio files from professional macOS sources. From lossless CAF (PCM/ALAC), the AAC encoding receives perfect input for optimal quality through iPod's acclaimed DAC.
iPod devices cannot play CAF files — the firmware supports AAC, MP3, ALAC, AIFF, and WAV only. Converting CAF to iPod-optimized AAC creates files that sync through iTunes and play with maximum battery efficiency via hardware AAC decoding.
The iPod Classic is renowned for its audio quality, particularly through its Wolfson/Cirrus Logic DAC. AAC from professional CAF sources takes full advantage of this hardware — producing excellent playback quality with hardware-decoded battery efficiency.
FFmpeg reads the CAF container, decodes to PCM, and encodes as AAC-LC at 256 kbps in M4A. If CAF contains AAC, stream copy avoids re-encoding. The M4A output includes iTunes-compatible metadata atoms for proper library display when synced to iPod.
From lossless CAF, AAC at 256 kbps sounds transparent through iPod's high-quality DAC. The iPod Classic's Wolfson WM8758 is particularly clean — the AAC encoding is the quality ceiling, not the playback hardware.
