WebMからALACへの変換について
WebM files contain Opus or Vorbis audio — high-quality open-source lossy codecs. ALAC (Apple Lossless Audio Codec) is Apple's lossless compression format, open-sourced in 2011, that compresses PCM to 50-60% size with zero data loss. ALAC integrates natively with Apple Music, iTunes, iPhone, iPad, and the entire Apple ecosystem.
WebMをALACに変換する理由
Extracting WebM audio to ALAC creates a lossless archival copy that integrates perfectly with Apple devices. The ALAC output serves as a master from which any future lossy format (AAC, MP3) can be derived without cascading generation losses. This is valuable when building Apple Music libraries from web audio sources.
ALAC is also the format that displays the 'Lossless' badge in Apple Music, adding perceived quality to imported web audio.
