A SIGNATURE FOR SOUND
Mivia Sign embeds a cryptographic signature directly into the waveform of your audio — inaudible, robust to re-encoding, and survives the internet. Proof of authorship that travels with the file.
THE SIGNATURE
Not metadata. Not a sidecar file. A cryptographic signature written into the waveform itself, below the psychoacoustic masking threshold — where human hearing doesn't operate.
The embedding is inaudible. Producers A/B-test against the original and can't pick which is signed. It's also durable: WAV, FLAC, AIFF, MP3, Instagram, SoundCloud, Bluetooth-speaker re-record, phone-camera capture — anywhere a listener would enjoy the track, the signature decodes.
You own the file. The file carries its own proof.
VERIFY
/verify takes any audio file you drop on it and returns authorship in under a second. Free forever, no sign-in, no rate limit for the public page.
01 · ANY FORMAT
If a listener would enjoy it, Mivia can read it. No pre-processing, no re-encoding on upload, no format tax.
02 · MP3 RESCUE
A heavy YouTube compression, a Bluetooth-speaker recording — Chromaprint fingerprint matching recovers authorship from the acoustic shape alone.
03 · CLEAN ANSWER
Or Unsigned, stated plainly. No probabilistic language. No "maybe this was a match." The answer is the file's, not an opinion.
TRUST MODEL
Every signature is anchored to the Bitcoin blockchain via OpenTimestamps at sign time. If Mivia disappeared tomorrow, the proof you own your work wouldn't.
01 · ANCHORED
Each sign produces an OpenTimestamps receipt, committed to Bitcoin on its next confirmation. The receipt travels with the manifest.
02 · PORTABLE
Verification uses open tooling. You can check authorship with the OpenTimestamps CLI against any public Bitcoin node — our server isn't in the loop.
03 · REVOCABLE
Installs use PKCE and are revocable per-install from your account. Revoke a stolen laptop without invalidating the signatures it already produced.
PREVENT YOUR MUSIC LEAKING
Send up to ten individually-watermarked copies of the same track — one per recipient. When a copy turns up somewhere it shouldn't, you run it through verify and Mivia tells you which recipient received it.
THE PLUGIN
Drop the Mivia Sign plugin on your master bus and every bounce is registered the moment it finishes. If a file turns up somewhere it shouldn't, the trail points home.
Zero added latency. Zero change to your audio. The plugin fingerprints each render and stores it against your account — your bounce on disk stays bit-identical.
01 · EVERY BOUNCE
02 · COLLABORATORS
03 · SESSION CONTEXT
