RMVBからM4Aへの変換について
M4A is the standard audio format for Apple's ecosystem — AAC audio in an MPEG-4 container supporting rich metadata, album art, chapters, and gapless playback. RMVB files store audio in RealAudio codecs (Cook, AAC, or HE-AAC variants) alongside video. Converting RMVB to M4A extracts the audio and packages it for seamless integration with iTunes, Apple Music, and all Apple devices.
RMVBをM4Aに変換する理由
RealAudio streams inside RMVB containers can't be played directly on Apple devices or imported into Apple's music ecosystem. M4A is the native audio format for Apple Music, iTunes, iPhone, iPad, and Apple Watch. The conversion discards unnecessary video data and produces an Apple-optimized audio file.
