First Claim
Patent Images
1. A method of signal processing, said method comprising:
- driving a directionally controllable transducer to produce a sound field that includes a beam;
producing a command in response to a representation of a gesture;
producing a filter configuration in response to said command; and
applying a spatially directive filter to an input signal to produce a multichannel signal,wherein the spatially directive filter is based on the filter configuration,wherein the gesture indicates a change in at least one among a direction of the beam and a width of the beam, and wherein the command is a command to perform the indicated change.

15. An apparatus for signal processing, said apparatus comprising:
-
means for driving a directionally controllable transducer to produce a beam; means for producing a command in response to a representation of a gesture; means for producing a filter configuration in response to said command; and means for performing a spatially directive filtering operation on an input signal to produce a multichannel signal, wherein the spatially directive filtering operation is based on the filter configuration, wherein the gesture indicates a change in at least one among a direction of the beam and a width of the beam, and wherein the command is a command to perform the indicated change. - View Dependent Claims (16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28)

29. An apparatus for signal processing, said apparatus comprising:
-
an audio output stage configured to drive a directionally controllable transducer to produce a beam; a gesture interpreter configured to produce a command in response to a representation of a gesture; a command interpreter configured to produce a filter configuration in response to said command; and a synthesizer configured to apply a spatially directive filter to an input signal to produce a multichannel signal, wherein the spatially directive filter is based on the filter configuration, wherein the gesture indicates a change in at least one among a direction of the beam and a width of the beam, and wherein the command is a command to perform the indicated change. - View Dependent Claims (30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42)

43. A non-transitory computer-readable medium having tangible features that cause a machine reading the features to:
-
drive a directionally controllable transducer to produce a sound field that includes a beam; produce a command in response to a representation of a gesture; produce a filter configuration in response to said command; and apply a spatially directive filter to an input signal to produce a multichannel signal, wherein the spatially directive filter is based on the filter configuration, wherein the gesture indicates a change in at least one among a direction of the beam and a width of the beam, and wherein the command is a command to perform the indicated change.
