#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 (it's home page was replaced with an advert for unrelated things in 2001), but it may be worth investigating and resurecting 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. |
