CAF (Core Audio Format) is Apple's professional audio container supporting any codec, unlimited file sizes, and rich metadata — native to Logic Pro and macOS Core Audio. Android Audio is a device-optimized preset producing OGG Vorbis or MP3 tuned for Android's Qualcomm Hexagon DSP and ARM NEON hardware decode paths.
Converting CAF to Android Audio extracts audio from Apple's professional container, decodes to PCM, and encodes for Android's hardware audio pipeline. From lossless CAF sources (PCM/ALAC), the Android encoder receives perfect input for optimal quality.
CAF has zero support outside Apple's Core Audio framework — Android cannot parse or play CAF files. Converting to Android Audio produces files that leverage hardware-accelerated Vorbis decoding on Qualcomm Snapdragon and MediaTek chipsets, maximizing battery life during playback.
From lossless CAF sources, the Android output achieves the best possible quality with a single lossy step from perfect PCM. This is the standard workflow when migrating professional macOS recordings to Android distribution.
FFmpeg reads the CAF container, decodes the enclosed audio to PCM, and encodes using libvorbis (OGG Vorbis quality 5, ~160 kbps VBR) or libmp3lame (MP3, 192 kbps). Vorbis is preferred for Android due to hardware decode acceleration on Qualcomm and MediaTek SoCs. From PCM or ALAC in CAF, only one lossy step occurs.
From lossless CAF sources, Vorbis at quality 5 produces transparent audio for most listeners. From lossy CAF sources (AAC), transcoding adds generation loss. The Android hardware decoder reproduces the encoded audio with full fidelity — no quality degradation from the decode path.
