Tietoa muunnoksesta MP4–ALAC
MP4 to ALAC conversion extracts audio from an MPEG-4 video and encodes it using Apple Lossless Audio Codec. ALAC compresses audio without discarding any data — every sample is mathematically identical when decoded. Apple open-sourced ALAC in 2011, and it is the lossless format natively supported by iTunes, Apple Music, iPhone, iPad, Mac, Apple TV, and HomePod.
Our converter decodes the audio from your MP4 and re-encodes it with the ALAC codec, producing an .m4a file (ALAC uses the M4A container). The result is a lossless audio file at roughly 50-60% of the uncompressed size, fully compatible with the Apple ecosystem.
Miksi muuntaa MP4 muotoon ALAC?
ALAC fills the gap between lossy AAC and massive uncompressed AIFF. If you want the best possible audio from your video content and you live in the Apple ecosystem, ALAC delivers bit-perfect quality at half the file size of uncompressed formats. Apple Music supports ALAC natively for its Lossless tier, so converting your video audio to ALAC ensures it integrates with your existing Apple library. AirPlay 2 transmits ALAC without additional transcoding, preserving quality through your HomePod or AirPlay speakers.
