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.
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.
FFmpeg decodes the MP2 subband audio to PCM at the original sample rate (typically 48 kHz for broadcast) and encodes to ALAC using linear prediction and entropy coding within an M4A container. ALAC achieves 40-60% compression over the raw PCM. The output preserves the broadcast sample rate and channel configuration. ALAC supports up to 32-bit/384 kHz, easily covering all broadcast MP2 formats.
Lossless relative to the decoded MP2 audio. ALAC preserves every sample from the MP2 decode without additional degradation. The quality ceiling is determined by the MP2 source — broadcast MP2 at 384 kbps provides excellent audio that ALAC faithfully captures.
