关于CAF转ALAC
CAF (Core Audio Format) is Apple's professional container supporting any audio codec and unlimited file sizes. ALAC (Apple Lossless Audio Codec) stores lossless compressed audio in M4A containers, natively supported by every Apple device. CAF may contain PCM, AAC, ALAC, IMA4, or other codecs; ALAC specifically provides lossless compression in the universally playable M4A format.
Converting CAF to ALAC extracts the audio, decodes to PCM if necessary, and re-encodes losslessly into an M4A container. This transforms professional macOS recordings into Apple's universal lossless distribution format.
为什么要将CAF转换为ALAC？
CAF files are limited to macOS Core Audio applications. ALAC in M4A plays natively on iPhone, iPad, Mac, Apple Watch, HomePod, Apple TV, and in iTunes/Apple Music. Converting CAF to ALAC makes your professional recordings universally playable across the entire Apple ecosystem.
ALAC in M4A also provides better metadata support for music libraries — album art, lyrics, chapter markers, and iTunes-specific tags that CAF does not support in the same way. For distributing professional recordings as music files, ALAC/M4A is the standard format.
