AI-generated track produced by Google Lyria with a C2PA manifest and SynthID watermark.

100% client-side

The file never leaves your machine. C2PA parsing happens in WASM, in your browser.

Plain English output

Who made it, what tool, when, with what watermark, signed by whom. No JSON unless you ask.

The Standard

What is C2PA?

C2PA (Coalition for Content Provenance and Authenticity) is the open standard behind Adobe Content Credentials. It embeds a cryptographically signed manifest inside a media file recording who created it, what tool produced it, and what edits were applied.

Read the spec on c2pa.org

Who

The claim generator that signed the file. Identity is cryptographically tied to a certificate issuer.

What

Actions like c2pa.created and c2pa.edited, plus digital source type (e.g. trainedAlgorithmicMedia for AI).

When

A signed timestamp from a trusted timestamping authority, so backdating is detectable.

How

Ingredients (source assets), watermarks like SynthID, hashes that bind the manifest to the bytes.

From the blog

Why we built this

C2PA is finally arriving in music files. Google Lyria already ships signed manifests inside downloaded MP3s. Most people in the music industry will not install a CLI to inspect them. This tool is the drag-and-drop alternative.

MusicTech Lab loves C2PA

We build C2PA into AI music platforms, distribution pipelines, rights workflows, and inspection tools. If you're shipping AI audio, integrating Content Credentials into a DSP, or need help thinking through how provenance fits your stack, we've been there.
