MP2からALACへの変換について
Converting MP2 to ALAC (Apple Lossless Audio Codec) decodes broadcast-standard MPEG Audio Layer 2 and compresses the resulting PCM losslessly into Apple's ecosystem format. ALAC reduces file size by 40-60% compared to uncompressed AIFF/WAV while guaranteeing bit-perfect reconstruction of the decoded audio.
This conversion is useful for building Apple-compatible archives of broadcast MP2 content — DAB radio recordings, DVB television audio, and DVD-Video soundtracks can be stored efficiently in ALAC with native playback on all Apple devices.
MP2をALACに変換する理由
Apple device users who archive broadcast recordings need a lossless format that plays natively on iPhone, iPad, Mac, and Apple TV. ALAC provides this while using 40-60% less storage than uncompressed AIFF or WAV. From broadcast MP2 at 48 kHz, ALAC preserves every decoded sample.
ALAC also works well as a decode-once intermediate — archive broadcast MP2 as ALAC, then create AAC or other lossy formats as needed without re-decoding the original MP2 stream.
