FELLERS MATTHEW C: Method for adaptive control and equalization of electroacoustic channels. DOLBY LABORATORIES LICENSING CORPORATION, Andersen Robert L, February 4, 2010: WO/2010/014663 (7 worldwide citation)

An electroacoustic channel soundfield is altered. An audio signal is applied by an electromechanical transducer to an acoustic space, causing air pressure changes therein. Another audio signal is obtained by a second electromechanical transducer, responsive to air pressure changes in the acoustic sp ...

Davis Mark F, Fellers Matthew C: Method and apparatus for encoding and decoding multiple audio channels at low bit rates. Dolby Lab Licensing, July 5, 2000: EP1016320-A2 (3 worldwide citation)

A split-band coding system combines multiple channels of input signals into various forms of composite signals and generates spatial-characteristic signals representing soundfield spatial characteristics in a plurality of frequency subbands. The spatial-characteristics signals may be generated in ei ...

FELLERS Matthew C, SEEFELDT Alan J, CROCKETT Brett G, DAVIDSON Grant A, FIELDER Louis D: Procédé et appareil pour réduire leffet du bruit ambiant sur des auditeurs, Method and apparatus for reducing the effect of environmental noise on listeners. Dolby Laboratories Licensing Corporation, FELLERS Matthew C, SEEFELDT Alan J, CROCKETT Brett G, DAVIDSON Grant A, FIELDER Louis D, ANDERSEN Robert L, December 22, 2011: WO/2011/159858 (2 worldwide citation)

A method and apparatus for enhancing a desired audio signal for delivery through an electroacoustic channel include obtaining a noise estimate attributable to an external disturbance, applying the noise estimate to a dynamic noise compensation (DNC) process to thereby condition the desired audio sig ...

Fielder Louis D, Davis Mark F, Fellers Matthew C: Decodage audio multidirectionnel, Multidirectional audio decoding. Dolby Laboratories Licensing Corporation, Dolby Laboratories Licensing Corporation, SMART & BIGGAR, September 24, 1998: CA2283838

An acoustic crossfeed canceller, intended for implementation in software, such that when run in real time on a personal computer,the canceller has very low mips requirements and uses a small fraction of available CPU cycles. Thus, for example, the program could beincluded with video games, CD-ROMs, ...
