Abstract
The technology generally relates to spatial audio communication between devices. For example, a first device and a second device may be connected via a communication link. The first device may capture audio signals in an environment through two or more microphones. The first device may encode the captured audio with direction information. The first device may transmit the encoded audio via the communication link to the second device. The second device may decode the encoded audio to be output by one or more speakers of the second device. The second device may output the decoded audio to recreate positions of the captured audio signals.
Claims20
A method comprising:
- receiving a first audio signal sensed by a first audio sensor, the received first audio signal sensed from first sound waves emitted by a source emitter, the first audio sensor oriented in a first direction with respect to the source emitter;
- receiving a second audio signal sensed by a second audio sensor, the received second audio signal sensed from second sound waves emitted by the source emitter, the second audio sensor oriented in a second direction with respect to the source emitter;
- determining, based on the received first and second audio signals, a combined direction, the combined direction related to the first direction and the second direction;
- generating audio data, the audio data:
- configured for output by an output device;
- and
- comprising an output audio signal associated with the first and second sound waves emitted by the source emitter;
- and
- encoding the audio data with direction information, the direction information based on the combined direction.
A device, comprising:
- a first audio sensor;
- a second audio sensor;
- and
- one or more processors, the one or more processors configured to:
- receive, by the first audio sensor, a first audio signal, the first audio signal sensed from first sound waves emitted by a source emitter, the first audio sensor oriented in a first direction with respect to the source emitter;
- receive, by the second audio sensor, a second audio signal, the second audio signal sensed from second sound waves emitted by the source emitter, the second audio sensor oriented in a second direction with respect to the source emitter;
- determine, based on the first and second audio signals, a combined direction, the combined direction related to the first direction and the second direction;
- generate audio data, the audio data:
- configured for output by an output device;
- and
- comprising an output audio signal associated with the first and second sound waves emitted by the source emitter;
- and
- encode the audio data with direction information, the direction information based on the combined direction.
A non-transitory computer-readable medium storing instructions, which when executed by one or more processors cause the one or more processors to:
- receive a first audio signal sensed by a first sensor, the first audio signal sensed from first sound waves emitted by a source emitter, the first audio sensor oriented in a first direction with respect to the source emitter;
- receive a second audio signal sensed by a second sensor, the second audio signal sensed from second sound waves emitted by the source emitter, the second audio sensor oriented in a second direction with respect to the source emitter;
- determine, based on the received first and second audio signals, a combined direction, the combined direction related to the first direction and the second direction;
- generate audio data, the audio data:
- configured for output by an output device;
- and
- comprising an output audio signal associated with the first and second sound waves emitted by the source emitter;
- and
- encode the audio data with direction information, the direction information based on the combined direction.
