Solutions · For publishers

Find the covers, interpolations and derivatives no master-side tool sees.

Composition-level matching identifies your songs even when the recording, key, tempo and performer are all different - the long tail of unlicensed covers, remixes and AI re-recordings that most rights tools miss entirely. Then we license or enforce, on your instruction.

What publishers face

Your song is everywhere. Your recording isn't.

Covers evade fingerprints

Recording-level fingerprinting is built to recognise the same performance. A cover in a new key with a new singer is a different recording - and invisible to it.

The long tail multiplies

One song becomes hundreds of covers, lyric videos, interpolations, remixes and AI re-recordings across platforms - each a potential licence or claim.

MASTERLABEL TOOLSCOMPOSITIONYOUR RIGHTS

Most tools are master-side

The enforcement market grew up around labels. Composition-level visibility - what publishers actually own - has been the gap.

What Sonproof does for publishers

Works-level detection, with your splits in mind.

  • Melody, harmony and structure matchingIdentifies covers, interpolations, live versions, remixes and AI re-recordings of your compositions across arrangements and performers.
  • Chain-of-title awareWriters, splits, sub-publishers and territories encoded per work; actions only within your verified share and scope.
  • License or enforce - your callEvery case carries evidence you can use either way: to issue a licence, to claim composition-side on program platforms, or to send a notice where no licence exists.
  • Separation from master rightsComposition and recording are registered, reviewed and enforced separately - no cross-contamination with label claims.
  • Human review on every caseComposition matches need judgement; a reviewer confirms the match and the rights before anything is sent.
