Patent number: 11399252Abstract: Simulation of sound objects and attributes based on time-varying recursive filter structures each comprising a vector of one or more state variables and a mutable number of sound input and/or sound output signals. For simulating sound reception, the recursive update of at least one state variable involves adding an input term obtained by linearly combining input sound signals being received, wherein said combination involves time-varying coefficients adapted in response to input reception coordinates associated with said input sound signals. For simulating sound emission, state variables are linearly combined wherein said combination involves time-varying coefficients adapted in response to output emission coordinates associated with said output sound signals. Attenuation or other effects induced by sound propagation and/or interaction with obstacles may be incorporated during sound emission and/or reception through scaling the time-varying coefficients involved therein.Type: GrantFiled: January 16, 2020Date of Patent: July 26, 2022Assignee: OUTER ECHO INC.Inventors: Esteban Maestre-Gomez, Julius O. Smith, Gary P. Scavone

Patent number: 10497378Abstract: A method for recognizing an audio sample locates an audio file that closely matches the audio sample from a database indexing a large set of original recordings. Each indexed audio file is represented in the database index by a set of landmark timepoints and associated fingerprints. Landmarks occur at reproducible locations within the file, while fingerprints represent features of the signal at or near the landmark timepoints. To perform recognition, landmarks and fingerprints are computed for the unknown sample and used to retrieve matching fingerprints from the database. For each file containing matching fingerprints, the landmarks are compared with landmarks of the sample at which the same fingerprints were computed. If a large number of corresponding landmarks are linearly related, i.e., if equivalent fingerprints of the sample and retrieved file have the same time evolution, then the file is identified with the sample.Type: GrantFiled: January 23, 2018Date of Patent: December 3, 2019Assignee: Apple Inc.Inventors: Avery Li-Chun Wang, Julius O.

Patent number: 9899030Abstract: A method for recognizing an audio sample locates an audio file that matches the sample from a database indexing original recordings. Each indexed file is represented in the database index by a set of landmark timepoints and associated fingerprints. Landmarks occur at reproducible locations within the file, while fingerprints represent features of the signal at or near the landmark timepoints, and the fingerprints are invariant with respect to time stretching of the sample. To perform recognition, landmarks and fingerprints are computed for the unknown sample and used to retrieve matching fingerprints from the database. For each file containing matching fingerprints, the landmarks are compared with landmarks of the sample at which the same fingerprints were computed. If a large number of corresponding landmarks are linearly related, i.e., if equivalent fingerprints of the sample and retrieved file have the same time evolution, then the file is identified with the sample.Type: GrantFiled: July 19, 2016Date of Patent: February 20, 2018Assignee: Shazam Investments LimitedInventors: Avery Li-Chun Wang, Julius O.
