A signature for sound.

What Mivia Sign does

Mivia Sign writes a cryptographic signature directly into the waveform of your audio — inaudible, robust to re-encoding, and resilient across the platforms your music passes through. Anyone can verify authorship with a drag-and-drop; only you can produce the signature.

How it works, in one paragraph

A small watermark sits below the psychoacoustic masking threshold, so listeners hear no difference from the original. Every signed file is anchored to Bitcoin via OpenTimestamps at sign time, so the record can be verified independently of Mivia. The web signer, the Projects library, and the DAW plugin all produce the same cryptography under the hood.

Who it's for

Producers, composers, and labels who want proof of authorship that travels with the file — before a demo hits a Dropbox link, before a bounce gets sent to a mastering engineer, before a track lands on streaming.
