US Patent:

8158870, Apr 17, 2012

Filed:

Jun 29, 2010

Appl. No.:

12/826623

Inventors:

Richard F. Lyon - Los Altos CA, US
Thomas C. Walters - San Francisco CA, US
David Ross - San Jose CA, US

Assignee:

Google Inc. - Mountain View CA

International Classification:

A63H 5/00

US Classification:

84609, 379 8801

Abstract:

A system, method, and computer readable storage medium generates an audio fingerprint for an input audio clip that is robust to differences in key, instrumentation, and other performance variations. The audio fingerprint includes a sequence of intervalgrams that represent a melody in an audio clip according pitch intervals between different time points in the audio clip. The fingerprint for an input audio clip can be compared to a set of reference fingerprints in a reference database to determine a matching reference audio clip.

International Classification:

G06F 3/16

US Classification:

700 94

Abstract:

Systems and techniques for removing a sound recording from an audio recording (e.g., an audio recording embedded in a media file) are presented. The system can include an identification component, a first subtraction component and a second subtraction component. The identification component identifies a sound recording in a mixed audio recording. The first subtraction component determines a local linear transformation of the sound recording and subtracts the local linear transformation of the sound recording from the mixed audio recording to generate a new mixed audio recording. The second subtraction component compares one or more segments of the sound recording with one or more corresponding segments of the new mixed audio recording and reduces a power level of the new mixed audio recording based at least in part on correlation of the one or more corresponding segments with the one or more segments.
