Music Identification and Monitoring

Identifying a known recording is a different problem from understanding music. It is the problem of rights and of monitoring: which song is playing, in this bar, through this microphone, over this crowd. And it is a problem where laboratory accuracy and deployed accuracy part company faster than almost anywhere else in audio.

Evaluate the way it will be used

Our work on audio fingerprinting combines contrastive and transfer learning, but the part we care most about is the real-world evaluation protocol: measuring identification through a microphone, in rooms, at distance, against noise and crowd, rather than on clean queries. We release the benchmark — deep architectures, training pipelines and database indexing techniques — so that the comparison can be repeated.

Where this runs

Museek developed a lightweight, device-friendly system for automatically monitoring and recognising music played in public venues — restaurants, hotels, cafes, clubs, bars — in collaboration with GEA, the official music copyright collective management organisation of Greece.

The same capability is delivered as a service in two European platforms: music fingerprinting in DeployAI, the European AI-on-Demand Platform, and song identification for monitoring music use in broadcast and public spaces in the PHAROS AI Factory.

If you run a venue network, a broadcaster or a rights organisation and need identification measured under your own conditions rather than a vendor’s, that is a conversation we have had before.
