Needle

The song identifier built for what you own.

Your vinyl, cassettes, CDs and obscure digital finds aren't in any public fingerprint database — especially when they're playing through a turntable, a tape deck, or the speakers in your room.

Needle changes that. Add your music library once — any source, any format. Needle generates acoustic fingerprints on the fly and discards the audio. Then drop the needle on a vinyl, pop in a cassette, or spin up a CD — Needle listens and tells you exactly what you're hearing.

Fingerprints, not files
