Verify a Certificate
Every song and instrumental produced in an AVH Studios studio carries a signed Certificate of Authorship & Provenance. Paste a certificate id (or scan the QR on a certificate PDF) to confirm the record is genuine, and drop in an audio file to prove it is the exact file the certificate seals — matched by its SHA-256 fingerprint.
🔎 Look up a record

🎧 Match an audio file
