Acoustic fingerprint opensource?

Question

Someone know any acoustic fingerprint API opensource or freeware? Preferable windows compatible. I only need the fingerprint part, not to connect to a remote DB to check audio metadata

Thanks

Answer 1

Have you already checked the ones listed in MusicBrainz documentation about audio fingerprinting?

haven't used it myself though

Answer 3

• Already mentioned MusicBrainz (and related projects: MusicDNS, may be something else).
• GraceNote (seems to be free for non-commertial use).
