Audio Content Credentials remover
Remove Content Credentials (C2PA) from an MP3
AI voice and audio tools increasingly attach a signed Content Credentials manifest, a C2PA record saying the clip was machine-made and where it came from. In an MP3 it sits inside the tag, not in the sound. Drop one in below to see whether yours has one, and take it out.

What this removes
It drops the C2PA manifest from the MP3's ID3 tag, the encapsulated object that carries the provenance claim and its signature, and keeps every other tag and the audio itself exactly as they were. The sound is never re-encoded. Afterwards a Content Credentials checker will simply report that the file has none.
What it does not touch
A manifest is not the same as an inaudible watermark. Removing it does not remove an audio watermark that a tool may add to the waveform in parallel, and it does not erase any record kept off the file that can be matched back to the clip by its sound. Those live in the audio or in the cloud, not in the tag, and this tool does not claim to reach them, that is what a heavier, GPU-backed cleaner is for.
Only MP3, for now
This works on MP3, where the manifest lives in the ID3 tag. Other containers such as WAV and M4A carry C2PA their own way, which is not handled here yet. The audio metadata remover can still clear an M4A or WAV by re-saving it, though that drops the other tags at the same time.
