MusicIP first marketed their fingerprinting algorithm and service as MusicDNS. In 2006, MusicIP reported that the MusicDNS database had more than 22 million fingerprints of digital audio recordings.[1] One of their customers was MetaBrainz Foundation, a non-profit company that used MusicDNS in their MusicBrainz and MusicBrainz Picard software products.[2][3]
Even so, MusicIP dissolved in 2008. The company's CEO, Andrew Stess, bought the rights to MusicDNS, renamed the software to AmpliFIND, and started a new company called AmpliFIND Music Services.[4][5] In 2011, Stess sold AmpliFIND to Sony, who incorporated it into the digital music service offerings of their Gracenote division.[6][7] Tribune Media subsequently purchased Gracenote, including the MusicDNS software.
How MusicDNS identifies a recording
editThis section needs additional citations for verification. (May 2024) |
To use the MusicDNS service, software developers write a computer program that incorporates an open-source software library called LibOFA.[8] This library implements the Open Fingerprint Architecture,[9][10] a specification developed during 2000–05 by MusicIP's previous incarnation, Predixis Corporation.
Through LibOFA, a program can fingerprint a recording, and submit the fingerprint to MusicDNS via the Internet. MusicDNS attempts to match the submission to fingerprints in its database. If the MusicDNS service finds an approximate match, it returns a code called a PUID (Portable Unique Identifier). This code does not contain any acoustic information; rather, it enables a computer program to retrieve identifying information (such as the song title and recording artist) from the MusicDNS database. The PUID code is a short, alphanumeric string based on the universally unique identifier standard.
The source code for LibOFA is distributed under a dual license: the GNU General Public License and the Adaptive Public License. The MusicDNS software that makes the fingerprints is proprietary.
