How we use it at Deezer

At Deezer, we have developed Radar to improve our user experience. Running analyses on the catalog enables us to flag duplicates and fraudulent audio files, before either removing them or discounting them from user searches.

By connecting Radar to our library, we can also use it to compile and complete metadata on podcasts, radio and audiobook feeds. From managing our catalog to improving user engagement, fingerprinting is ever present!

Sort any catalog based on the music it contains

Scan your catalog by individual song in order to identify and sort content. For example, find all movies, shows, documentaries, etc. that contain a specific song in their audio track.

Provide new filters and routes for catalog search, enabling users to find the content they’re looking for, from movies to radio to TV shows, podcasts, songs and artists.

Identify fraudulent audio

Easily spot unauthorized copies of content and songs with this music identifier.

Detect leaks or early releases of new music in your catalog.

Detect versions and allocate rights

Identify and flag different versions (radio, long or short version, etc.) in your catalog and improve reporting and royalties allocation.

Find fallback audio tracks when needed

Quickly identify legally-acceptable song versions when the original is unavailable in a user’s country.

Automatically detect songs on any audio file

Identify songs on audio files from radio shows, movies, podcasts etc.
