Detect Content Credentials and AI provenance in your audio files
Drop audio files to get started
MP3 · FLAC · M4A · WAV · OGG · OPUS — up to 500 MB each
Content Credentials (C2PA, Adobe) can be stored in an audio file's metadata — ID3v2 tags for MP3, Vorbis comments for FLAC/OGG, or custom iTunes atoms for M4A/AAC. This audio provenance checker reads the file's real tags and spots provenance-related fields: C2PA manifest, claim signature, an "AI-generated" assertion, ingredients and actions. Nothing is changed — it's a read-only analysis, useful for verifying a podcast, an AI voice clone, or an auto-generated music track before publishing.
Stored in ID3/Vorbis/iTunes tags depending on the audio format.
The user-facing layer of provenance (Adobe).
A field declaring AI generation or voice cloning, with a model name.
The checker reads each tag family depending on the container.
The audio file is never modified by the analysis.
Detects manifests declaring voice synthesis or cloning.
A file exported from an AI voice generator, a mastering tool, or a voice-cloning service can embed a manifest in its metadata. Compatible Adobe viewers display it as Content Credentials. But most streaming platforms (Spotify, YouTube Music, SoundCloud) re-encode or repackage audio files on ingestion, which often wipes this metadata layer — hence the value of checking the source file before submission.

Streaming services often repackage audio, wiping tags.
Read-only analysis — the waveform is never touched.
As of August 2, 2026, Article 50 of the EU AI Act (Regulation (EU) 2024/1689) makes machine-readable marking of synthetic content mandatory — including AI-generated or AI-modified audio (cloned voices, synthetic music) — across the EU, with fines of up to €15 million or 3% of global turnover. Knowing whether an audio file already carries a certificate avoids unwanted labels before release.

A provenance certificate is not a ranking signal for a podcast or music track. For audio SEO, prioritise clean ID3 tags — title, artist, album, description — and a descriptive transcript or episode notes for indexing. C2PA mostly helps editorial trust and GEO (Generative Engine Optimization) — AI assistants are more likely to cite a source with clear provenance.

Found provenance you want to remove?
Upload the audio file
MP3, M4A, AAC, FLAC, WAV, OGG, OPUS, WMA, AIFF — up to 500 MB.
Read the tags
Read mode lists every tag stored in the file.
Spot the provenance
Look for c2pa / contentcredential fields among the tags.
No. It reads metadata read-only (ExifTool in extraction mode) and writes nothing to the file.
No. An inaudible audio watermark, a platform-side marking or out-of-metadata proof escapes the read. And a manifest can be partial or inaccurate.
MP3, M4A, AAC, FLAC, WAV, OGG, OPUS, WMA and AIFF (up to 500 MB per file).
Usually in a custom TXXX frame of the ID3v2 block. For FLAC/OGG, in a Vorbis comment; for M4A, in a custom iTunes atom.
Yes — use the C2PA Audio Remover or the universal C2PA Credentials Remover to strip the manifest.
No. The manifest attests a signed claim of origin, not absolute truth. For legal obligations, refer to EU AI Act Article 50.
