MusicBrainz Picard is a free and open-source software application for identifying, tagging, and organising digital audio recordings. It was developed by the MetaBrainz Foundation, a non-profit company that also operates the MusicBrainz database.
Picard identifies audio files and Compact Discs by comparing either their metadata or their acoustic fingerprints with records in the database. Audio file metadata (or "tags") are a means for storing information about a recording in the file. When Picard identifies an audio file, it can add new information to it, such as the recording artist, the album title, the record label, and the date of release. In some cases, it can also add more detailed information, such as lists of performers and their instruments. The source of this information is the MusicBrainz database, which is curated by volunteers. The more information the database has about a recording, the more Picard can embed in users' audio files.
Picard also has tag editing features, and is extensible with plug-ins. The main program is written in the Python programming language. It replaces an earlier tag editor developed for MusicBrainz. Whereas the original version was a typical tag-editor, Picard is album-oriented, and supports more computing platforms.
In 2006, Picard's developers added a facility for identifying audio files using an acoustic fingerprinting scheme called MusicDNS. They replaced MusicDNS with AcoustID in 2009. In the interim, Picard was completely rewritten in order to switch from the wxPython library to PyQt, and also to make it portable to Mac OS X. The rewritten application was published as version 0.9.0. Picard now also uses the Mutagen library.
