Chromaprint
AcoustID is a webservice for the identification of music recordings based on the Chromaprint acoustic fingerprint algorithm. It can identify entire songs but not short snippets. By 2017, the free service had 34 million "fingerprints" in store and every day acquired between 15 and 20 thousand new entries and answered around five million search queries. AcoustID is integrated into the audio file metadata editors MusicBrainz Picard, Picard, Jaikoz and Puddletag, for example. Chromaprint In October 2009 MusicIP was acquired by AmpliFIND. 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. The oldest entry in the DB is from 8 Oct 2010. While AcoustID and Chromaprint ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
MusicBrainz
MusicBrainz is a MetaBrainz project that aims to create a collaborative 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 information on the Internet. MusicBrainz has expanded its goals to reach beyond a CD metadata (this is information about the performers, artists, songwriters, etc.) storehouse to become a structured online database for music. MusicBrainz captures information about artists, their recorded works, and the relationships between them. Recorded works entries capture at a minimum the album title, track titles, and the length of each track. These entries are maintained by volunteer editors who follow community written style guidelines. Recorded works can also store information about the release date and country, the CD ID, cover art, acoustic fingerprint, free-form annotation text and other metadata. , Musi ...

Acoustic Fingerprint
An acoustic fingerprint is a condensed digital summary, a fingerprint, deterministically generated from an audio signal, that can be used to identify an audio sample or quickly locate similar items in an audio database. Practical uses of acoustic fingerprinting include identifying songs, melodies, tunes, or advertisements; sound effect library management; and video file identification. Media identification using acoustic fingerprints can be used to monitor the use of specific musical works and performances on radio broadcast, records, CDs, streaming media and peer-to-peer networks. This identification has been used in copyright compliance, licensing, and other monetization schemes. Attributes A robust acoustic fingerprint algorithm must take into account the perceptual characteristics of the audio. If two files sound alike to the human ear, their acoustic fingerprints should match, even if their binary representations are quite different. Acoustic fingerprints are not h ...

MusicBrainz Picard
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. MusicBrainz Picard has tag editi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Jaikoz
Jaikoz is a Java program used for editing and mass tagging music file tags. Jaikoz generates acoustic fingerprints from music files using the AcoustId service, it can then look up the metadata from MusicBrainz using the AcoustId, additionally it can match based on metadata to MusicBrainz or Discogs. Matching is first applied at album level, falling back to track level where a match at album level could not be made. This allows Jaikoz to automatically fix most of a users song collection. Jaikoz uses a relatively unusual spreadsheet metaphor for both viewing and editing data, and allows editing of over fifty fields using this spreadsheet interface, the underlying jaudiotagger tag library is released under LGPL and is used by various Java applications. Jaikoz is commercially licensed software, written in Java 1.5 by Paul Taylor. A shareware version, in which changes can only be saved to 20 files during one use, is also available as a 30-day free trial. 10% of every sale is paid to ...

Puddletag
Puddletag is a graphical audio file metadata editor ("tagger") for Unix-like operating systems. It is free and open-source software subject to the terms of the GNU General Public License (GPL) version 3. In most major desktop Linux distributions, it is available from standard package repositories. Under Arch Linux(-based ones) it can be obtained from community repositories. The user interface is modeled after the popular Windows freeware ''Mp3tag''. It uses a spreadsheet-like layout so that all the tags a user may want to edit by hand are visible and easily editable. All the other audio taggers available for Linux take a different approach to user interface design. The interface elements can be freely arranged. In July 2008, the first version (0.1) was released via SourceForge. The website counted several thousand downloads for each release before the project finally left the platform in early 2016 and was included in the package sources of most major Linux distributions.

MusicIP
AmpliFIND is an acoustic fingerprinting service and a software development kit developed by the US company MusicIP. 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. One of their customers was MetaBrainz Foundation, a non-profit company that used MusicDNS in their MusicBrainz and MusicBrainz Picard software products. 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. In 2011, Stess sold AmpliFIND to Sony, who incorporated it into the digital music service offerings of their Gracenote division. Tribune Media subsequently purchased Gracenote, including the MusicDNS software.

Pitch Class
In music, a pitch class (p.c. or pc) is a set of all pitches that are a whole number of octaves apart; for example, the pitch class C consists of the Cs in all octaves. "The pitch class C stands for all possible Cs, in whatever octave position." Important to musical set theory, a pitch class is "all pitches related to each other by octave, enharmonic equivalence, or both." Thus, using scientific pitch notation, the pitch class "C" is the set : = . Although there is no formal upper or lower limit to this sequence, only a few of these pitches are audible to humans. Pitch class is important because human pitch-perception is periodic: pitches belonging to the same pitch class are perceived as having a similar quality or color, a property called "octave equivalence". Psychologists refer to the quality of a pitch as its "chroma". A ''chroma'' is an attribute of pitches (as opposed to ''tone height''), just like hue is an attribute of color. A ''pitch class'' is a set of all pit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
