Abstract
An apparatus includes one or more processors configured to receive orientation data and to select, based on the orientation data, a particular filter from among multiple filters. The one or more processors are configured to perform signal processing operations associated with three-dimensional (3D) sound data based on the particular filter.
Claims20
An apparatus comprising:
- one or more processors configured to:
- obtain ambisonic data, that represent ambisonic coefficients of an order greater than one, based on an original three-dimensional (3D) sound field;
- obtain orientation data that identifies a particular orientation of a loudspeaker array;
- select, based on the orientation data, a particular filter that substantially matches the particular orientation of the loudspeaker array, from among multiple filters, wherein each of the multiple filters defines a plurality of filter values to be applied to the ambisonic data;
- and
- perform signal processing operations associated with the original 3D sound field that includes the ambisonic data based on the particular filter, wherein the particular filter is a first filter associated with a first orientation of the loudspeaker array.

A method comprising:
- obtaining ambisonic data, that represent ambisonic coefficients of an order greater than one, based on an original three-dimensional (3D) sound field;
- obtaining orientation data, at one or more processors, wherein the orientation data identifies a particular orientation of a loudspeaker array;
- selecting, at the one or more processors and based on the orientation data, a particular filter that substantially matches the particular orientation of the loudspeaker array, from among multiple filters, wherein each of the multiple filters defines a plurality of filter values to be applied to the ambisonic data;
- and
- performing signal processing operations associated with the original 3D sound field that includes the ambisonic data based on the particular filter, wherein the particular filter is a first filter associated with a first orientation of the loudspeaker array.
2 more elements
A non-transitory computer-readable medium comprising instructions that, when executed by one or more processors, cause the one or more processors to:
- obtain ambisonic data, that represent ambisonic coefficients of an order greater than one, based on an original three-dimensional (3D) sound field;
- obtain orientation data that identifies a particular orientation of a loudspeaker array;
- select, based on the orientation data, a particular filter that substantially matches the particular orientation of the loudspeaker array, from among multiple filters, wherein each of the multiple filters defines a plurality of filter values to be applied to the ambisonic data;
- and
- perform signal processing operations associated with the original 3D sound field that includes the ambisonic data based on the particular filter, wherein the particular filter is a first filter associated with a first orientation of the loudspeaker array.
