Spatial audio aggregation for multiple sources of spatial audio
First Claim
1. A method comprising:
- receiving data representing a position for a region in space adjacent a first media device including a first subset of transducers associated with a first channel and a second subset of transducers associated with a second channel;
determining a second media device adjacent to the region in space;
determining a location of the second media device;
selecting a filter configured to project spatial audio to the region in space;
aggregating the first subset of transducers and the second subset of transducers to propagate either the first channel or the second channel as a first aggregated channel; and
emitting the first aggregated channel from the first and the second subsets of transducers to the region in space.

Abstract
Various embodiments relate generally to electrical and electronic hardware, computer software, wired and wireless network communications, and audio and speaker systems. More specifically, disclosed are an apparatus and a method for processing signals for optimizing audio, such as 3D audio, by adjusting the filtering for cross-talk cancellation based on listener position and/or orientation. In one embodiment, an apparatus is configured to include a plurality of transducers, a memory, and a processor configured to execute instructions to determine a physical characteristic of a listener relative to the origination of the multiple channels of audio, to cancel crosstalk in a spatial region coincident with the listener at a first location, to detect a change in the physical characteristic of the listener, and to adjust the cancellation of crosstalk responsive to detecting the change in the physical characteristic to establish another spatial region at a second location.

20. A media device comprising:
-
a plurality of transducers configured to emit acoustic signal into an adjacent region, at least a subset of the plurality of transducers oriented relative to a reference line; a plurality of filters configured to project spatial audio to a portion of the region in space, each of the filters corresponding to a different portion of the region in space; a position determinator configured to determine a position adjacent the media device; and a controller configured to determine a location of a second media device adjacent to the region in space and to select a filter associated with the position to propagate the spatial audio to the position, the controller further configured to aggregate the first subset of transducers and the second subset of transducers to propagate either a first channel or a second channel of spatial audio as a first aggregated channel, and emit the first aggregated channel from the first and the second subsets of transducers to the region in space.
