Audio Provenance
Prove any recording is from a verified human creator.
ObraVera embeds tamper-proof credentials into audio recordings that survive compression, format conversion, and platform processing. Prove provenance at any point in the distribution chain.
AI voice cloning is here. Your members need proof their recordings are real.
Voice Cloning
Voices cloned without consent for commercial use.
Metadata Stripped
No provenance once metadata is stripped.
Creators need credentials that live inside the audio itself.
Acoustic verification — without transferring any file.
Hold your phone near a speaker playing back an ObraVera-authenticated recording. The verifier listens for the embedded mark — no file transfer needed. No audio is stored.
- Designed for speaker and broadcast playback
- Designed to survive common platform processing
- Typically ~20 seconds of capture — no file access needed
The Hidden Signal
Inaudible to humans. Unmistakable to the detector.
The audio waveform below looks normal. The ObraVera watermark is embedded inside the signal at a level imperceptible to the ear. Watch the detector sweep and reveal the hidden credential layer.
If one layer is stripped, others remain.
Acoustic Watermark
Inaudible, embedded in the audio signal itself
Acoustic Fingerprint
Detects tampering and unauthorized edits
Cryptographic Signature
Mathematical proof of authenticity
Registry Recovery
Credentials recovered even when metadata stripped
Designed to survive what platforms throw at it.
In internal testing, survives -14 LUFS loudness normalization under standard production conditions.
Supported Formats
Audit-Ready
Proof you can show a client — or a union.
As AI transparency obligations converge, studios and unions need evidence and workflows — not just trust.
Signed Custody Chain
Every credential is cryptographically signed at the point of creation — immutable, timestamped, and registry-anchored.
Local Verification
Verify any file without uploading audio. Your content stays yours — verification runs without transferring the recording.
Receipts When You Need Them
Even when metadata is stripped, registry-anchored credentials provide documentary evidence for disputes and licensing.
