MusicBrainz is a project that aims to create an open data music database that is similar to the freedb project. MusicBrainz Was founded in response to the restrictions Placed on the Compact Disc Database (CDDB), a database for software applications to look up audio CD ( compact disc ) information on the Internet. MusicBrainz has expanded its goals to reach beyond a compact disc metadata (this is information about the performers, artists, songwriters, etc.). [5] [6]

MusicBrainz captures information about artists, their recorded works, and the relationships between them. Recorded works entries at least the track title, track titles, and the length of each track. These entries are maintained by volunteer editors who follow community written style guidelines . CD, cover art , acoustic fingerprint , free-form annotation text and other metadata. As of 26 July 2016 , MusicBrainz contained information about roughly 1.1 million artists, 1.6 million releases, and 16 million recordings. [3] End-users can use software that communicates with MusicBrainz to add metadata tags to their digital media files,

Cover Art Archive

MusicBrainz allows to upload cover art images of releases to the database; These images are hosted by Cover Art Archive (CAA), a joint project between Internet Archive and MusicBrainz started in 2012. Internet Archive provides the bandwidth, storage and legal protection for hosting the images, while MusicBrainz stores public access through the web And via an API for third parties to use. As with other contributions, the MusicBrainz community is in charge for maintaining and reviewing the data. [7] Cover art is also available for and some other online resources,


Besides collecting metadata about music, MusicBrainz also allows the recordings by their acoustic fingerprint . A separate application, such as MusicBrainz Picard, must be used for this.

Proprietary services

In 2000, MusicBrainz started using Relatable ‘s patented TRM (a recursive acronym for TRM Recognized Music) for acoustic fingerprint matching. This feature attracted many users and allowed the database to grow quickly. However, by 2005 TRM was showing scalability issues as the number of tracks in the database had reached into the million. This issue was resolved in May 2006 when MusicBrainz partnered with MusicIP (now AmpliFIND ), replacing TRM with MusicDNS. [8] TRMs were phased out and replaced by MusicDNS in November 2008.

AcoustID and Chromaprint

In October 2009 MusicIP was acquired by AmpliFIND . [9] Some time after the acquisition, the MusicDNS service began having intermittent problems. Since the future of the free identification service was uncertain, a replacement for it was sought. The Chromaprint acoustic fingerprinting algorithm, the basis for AcoustID identification service, was started in February 2010 by a long-time MusicBrainz contributor Lukáš Lalinský. [10]While AcoustID and Chromaprint are not officially MusicBrainz projects, they are closely tied with each other and both are open source. Chromaprint works by analyzing the first two minutes of a track, detecting the strength in each of 12 pitch classes , storing these 8 times per second. Additional post-processing is then applied to this fingerprint while retaining patterns. [11] The AcoustID search server then searches the database of fingerprints by similarity and returns the AcoustID identify along with MusicBrainz recording identifiers if known.


Since 2003 [12] MusicBrainz’s core data (artists, recordings, releases, and so on) are in the public domain , and additional happy Including moderation data (Essentially every original glad contributed by users and Its elaborations) is Placed under the Creative Commons CC-BY-NC-SA -2.0 license. [13] The relational database management system is PostgreSQL . The server software is covered by the GNU General Public License . The MusicBrainz client software library , libmusicbrainz , is licensed under the GNU Lesser General Public License , Which allows the use of the code by proprietary software products. In December 2004, the MusicBrainz project was turned over to the MetaBrainz Foundation , a non-profit group, by its creator Robert Kaye. [14] On January 20, 2006, the first commercial venture to use MusicBrainz was the Barcelona , Spain -based Linkara in their Linkara Música service. [15] On 28 June 2007, BBC announced that it has licensed musicBrainz’s live data to increase their music Web pages. The BBC online music editors will also join the MusicBrainz community to contribute their knowledge to the database. [16] On 28 July 2008, The beta of the new BBC Music site was launched, which publishes a page for each MusicBrainz artist. [17] [18]
