Scan audio metadata privately.
Inspect a local MP3 or WAV file for readable format and encoder information. This scan does not prove whether speech is AI-generated or whether a provider watermark exists.
See what your file contains.
Inspect an MP3 or WAV container, audio format, and selected readable encoder strings in your browser. A byte match is not proof of AI origin or watermark status.
Your file stays in this browser until you choose to submit it separately.
Readable byte signatures
Container tags such as ID3, Lavf or LAME can identify encoding history, but acoustic classifiers analyze the sound itself. A C2PA byte match is not a valid provenance verification. For a provider watermark, use its supported verifier. Our audio processing and QA address the supplied recording as a whole; results vary.
