Detection built for evidence, not estimates.
nnuma combines audio fingerprinting, independent verification, entity resolution and forensic capture in one system, designed from the start to produce evidence that holds.
Five stages, one chain of evidence.

It recognises the recording through every edit.
Brand content rarely uses a track as released. It is cut, sped up, pitched or placed under a voice-over. Our fingerprinting is built to recognise the master through those transformations, from a passage of a few seconds.
Dance and pop productions share drums, loops and sounds, which can mislead a fingerprint on its own. Every match therefore passes a second, independent spectral comparison against decoy recordings. Only passages that are clearly the client's master proceed, and each is then reviewed by a person.

What the system does.
- Fingerprinting
- Landmark-based audio hashing against the client's master recordings
- Robustness
- Edits, partial use, voice-over, background noise, tempo and pitch changes from 0.90× to 1.30×
- Verification
- Second, independent spectral comparison against decoy recordings, followed by human review

Continuous, not occasional.
Brands publish every day and campaigns disappear within weeks. The system monitors continuously and seals evidence the moment a use is found.
