#REDIRECT [[Fingerprinting]]
Audio fingerprints are identifiers for audio files based on the contained audio data.

Up to early 2006 [[MusicBrainz]] has used Relatable's [[TRM]], which is an algorithm matching files by audio fingerprints. However, we have been [[Getting Rid Of TRM|GettingRidOfTRM]], because we have reached the limits of scalability, and performance is not as good as we would like. Because the server is closed-source, we have no way to fix either of these problems.

For a short while we debated whether we should attempt to build our own open source [[Future Proof Fingerprint|FutureProofFingerPrint]]<code><nowiki></nowiki></code>ing technology, but nobody was there who could have done the work.

Since March 2006 [[MusicBrainz]] collaborates with [[MusicIP]] who operate the [[MusicDNS]] service. Their (proprietary but much better) [[PUID]]s have been integrated into the Picard 0.7.0. See [[PUID]] and [[How PUIDs Work|HowPUIDsWork]] for details.

==Known Audio Fingerprinting Systems==

===Open source systems:===

* The fingerprint in Kurt Rosenfeld's [[FDMF]]
* Freetantrum songprint
<ul><li style="list-style-type:none">There is a project called [http://sourceforge.net/projects/freetantrum freetantrum] on Sourceforge. 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.
</ul>
* MusicURI, a project trying to combine audio fingerprinting with text based search. More info on project [http://semedia.deit.univpm.it/musicuri/ homepage]. The GPL source code is available at [http://sourceforge.net/projects/mpeg7audiodb SourceForge].
* A possible [[Future Proof Fingerprint|FutureProofFingerPrint]] algorithm that we could code has been Proposed by Geoff Schmidt, formally of Tuneprint.
* [http://www.foosic.org/libfooid.php libFooID], an audio fingerprinting library used by, and developed for [http://www.foosic.org/ foosic].

===Commercial systems:===

* Relatable's [[TRM]]
<ul><li style="list-style-type:none">The system [[MusicBrainz]] originally used. This is going to be phased out as soon as [[PUID]]s work better than TRM.
</ul>
* [[MusicIP]]'s [[PUID]] (formerly [[MusicMagic]]/Predixis)
<ul><li style="list-style-type:none">The [[PUID]] technology has been integrated into the [[MusicBrainz]] since March 2006 and into Picard since version 0.7.0 released in July 2007. See their [http://www.freshpatents.com/Audio-fingerprinting-system-and-method-dt20050324ptan20050065976.php patent application] for details on the technology.
</ul>
* AudibleMagic
<ul><li style="list-style-type:none">[http://www.econtentmag.com/Articles/ArticleReader.aspx?ArticleID=4473&IssueID=128 This article] compares business models for Philips & Audible Magic
</ul>
* Philips (also licensed by SNOCAP)
<ul><li style="list-style-type:none">[http://ismir2002.ismir.net/proceedings/02-FP04-2.pdf http://ismir2002.ismir.net/proceedings/02-FP04-2.pdf] [http://ict.ewi.tudelft.nl/pub/doets/paper027.pdf http://ict.ewi.tudelft.nl/pub/doets/paper027.pdf] [http://wwwiti.cs.uni-magdeburg.de/iti_amsl/lehre/03_SoSem/mmsec_v/scripte/vorles-mm-03-6.3.pdf This presentation] (in PDF) has a few slides on the Philips system as well:
