关于WMV转ALAC
WMV files carry audio encoded as WMA (Windows Media Audio) — a Microsoft-proprietary codec that Apple devices cannot play natively. ALAC (Apple Lossless Audio Codec) is Apple's lossless compression standard, open-sourced in 2011, delivering roughly 50% compression of PCM audio with guaranteed bit-perfect reconstruction. Converting WMV to ALAC extracts the audio from Microsoft's format and compresses it losslessly in Apple's ecosystem-native codec, stored in an M4A container compatible with every Apple device.
为什么要将WMV转换为ALAC？
ALAC is the default lossless audio format for Apple Music, iTunes, iPhone, iPad, HomePod, and AirPlay 2. If you have WMV recordings with audio you want to preserve in lossless quality for the Apple ecosystem, ALAC provides bit-perfect audio in a format that syncs naturally to iCloud Music Library and plays on every Apple product without third-party apps.
