The client-side audio fingerprinting library ( fplib) is open-source. jHears is an acoustic fingerprinting framework based on FutureProofFingerPrint design by Geoff Schmidt (formerly of Tuneprint).

It seems to be a dead project (its home page was replaced with an advert for unrelated things in 2001), but it may be worth investigating and resurrecting the code they produced. An audio fingerprinting library used by, and developed for foosic. Audio fingerprinting solution developed by the Echo Nest. Uses the "Philips Robust Hashing" algorithm. Based on the pHash audio fingerprinting library, developed by the same authors.
MusicURI, part of the Mpeg-7 Audio DB project. The fingerprint in Kurt Rosenfeld's FDMF. Other audio fingerprinting systems Open Source In June 2020 all PUID edits were removed from the database. PUID support was removed from the MusicBrainz server in October 2013. The client-side audio fingerprinting library, libofa, is open-source. See the patent application for details on the technology. If/when that database goes away, they become useless. PUIDs are also quite opaque, being nothing more than a unique number referencing a database outside of MusicBrainz’ control. Over time, the operators have become less and less interested in running the server, to the point where today it is barely working, if it works at all. The fingerprinting process is slow, both on the client side and the server side. Only looking up existing fingerprints was possible in Picard, new fingerprints had to be created using either MusicIP Mixer or the command line genpuid (no longer available, the latest version is mirrored on our ftp server). The fingerprint submission system is not open source, and as such could not be included in Picard. This system was better than TRM, but still had several major problems: MusicBrainz started to use these IDs in March 2006 and they were implemented in Picard 0.7.0 released in July 2006. Gracenote is expected to discontinue the public service soon, and it already appears to be largely non-functional. This was initially operated by MusicIP (later AmpliFIND Music Services), and bought by Gracenote in June 2011. PUIDs were MusicBrainz’ second audio fingerprinting system. TRM support was removed in November 2008. The server was also incapable of handling the number of TRMs needed for MusicBrainz, and Relatable didn’t seem to be interested in supporting it further. This system worked reasonably well for finding duplicate music files on a local system, but had problems with collisions (different-sounding audio which got the same ID) and duplicates (same-sounding audio which has different IDs). The client-side audio fingerprinting library was open source and integrated into libmusicbrainz. This system was used in the original MusicBrainz tagger application. This system was created by Relatable, and added to MusicBrainz in 2000. TRM (TRM Recognizes Music) IDs were MusicBrainz’ first audio fingerprinting system. AcoustID fingerprints have their duration recorded, making it easy to discard certain incorrect links between recordings and acoustIDs. 
It gives the ability to visually compare music.It is actively developed, along with supporting software.ĪcoustID support was implemented in Picard 0.16 released in October 2011. This was created by Lukáš Lalinský, and made public around January 2011. AcoustID is MusicBrainz’ third and most recent audio fingerprinting system.
