ALAC stores lossless audio in Apple's M4A container. AVI (Audio Video Interleave) is Microsoft's legacy RIFF-based multimedia container from 1992, supporting MP3 and PCM audio. Converting ALAC to AVI decodes the lossless audio and wraps it in the legacy container.
This conversion bridges Apple's lossless ecosystem with legacy Windows/industrial AVI systems. Since ALAC is lossless, the AVI output benefits from perfect source material — PCM in AVI produces a lossless transfer.
Legacy video editing tools, CCTV systems, and industrial media players require AVI format. Converting ALAC audio to AVI enables professional Apple recordings to enter these older systems.
Using PCM within AVI preserves the full lossless quality of the ALAC source, making this conversion completely lossless when uncompressed audio is chosen.
FFmpeg decodes ALAC from M4A to perfect PCM, then writes to AVI as either PCM (lossless) or MP3 (lossy). AVI cannot contain ALAC natively. The lossless decode ensures optimal quality regardless of the AVI audio codec chosen.
PCM in AVI from ALAC is perfectly lossless — bit-for-bit identical to the original recording. MP3 in AVI introduces a single lossy step from perfect source material, producing optimal MP3 quality.
