APPARATUS AND METHOD FOR GROUPING TEMPORAL SEGMENTS OF A PIECE OF MUSIC
U.S.
Patent No. 7,345,233, issued Mar. 18, 2008, relates to grouping
temporal segments within music that have been automatically obtained,
according to their similarity. Thus, repeating parts within music can
be determined by the machine, which eventually leads to better
comprehension of the structure of a musical piece, as well can be used
to characterize musical items.

AUTOMATIC IDENTIFICATION OF SOUND RECORDINGS
U.S. Patent No. 7,328,153, issued February 5, 2008, relates to the
fundamental concepts embodied in Gracenote's MusicID File audio
fingerprint extraction and identification product. The patent describes
a method for identifying digital recordings from unidentified
recordings by extracting one or more fingerprints from an unidentified
recording and searching a reference database for candidate matches. The
patent covers the methods for computing fingerprints from
time-frequency ranges and weighted frequency spectra of selected
portions of the recording. The patent also covers creating a reference
fingerprint database that is searched using a Search by Range Reduction
(SRR) method for efficiency. The searching includes the computation of
distance measures to determine the suitability of a match.

SYSTEM FOR COLLECTING USE DATA RELATED TO PLAYBACK OF RECORDINGS
U.S. Patent No. 6,330,593, issued December 11, 2001, relates to
entertainment content complementary to a musical recording that is
delivered to a user's computer by means of a computer network link. The
user employs a browser to access the computer network. A plug-in for
the browser is able to control an audio CD or other device for playing
the musical recording. A script stored on the remote computer accessed
over the network is downloaded. The script synchronizes the delivery of
the complementary entertainment content with the play of the musical
recording.
