- For
- IAMF audio creators and people checking MP4 audio files
- Worth noticing
- The decode check uses libiamf on supported Opus or PCM mixes only, and only for files up to 64 MiB.
Field notes
The page presents IAMF v1.1.0 checks alongside separate YouTube and music-partner recommendations. For files up to 64 MiB, it says the inspector also decodes supported Opus or PCM mixes with libiamf; larger files do not receive that decode check. The homepage cautions that a clear report is not proof of full IAMF conformance, and says credits are charged once analysis is authorized, even for cancelled or incomplete runs.
