Abstract

An embodiment provides a system, including: a sensor; a processor operatively coupled to the sensor; and a memory storing instructions executable by the processor to: capture, using the sensor, depth data related to at least one position within an area; determine characteristics associated with the at least one position based on the depth data; and configure audio output to one or more speakers of an audio system based on the acoustic characteristics. Other aspects are described and claimed.

Claims

1. A system, comprising:

a sensor;

a processor operatively coupled to the sensor; and

a memory storing instructions executable by the processor to;

capture, using the sensor, depth data related to at least one position within an area;

identify one or more user listening positions within the area using the depth data, wherein the user listening positions are identified based upon object locations within the area;

determine characteristics associated with the one or more user listening positions based on the depth data;

generate, based upon the determined characteristics, a sound profile of the area; and

configure, based on the sound profile, audio output to a plurality of speakers of an audio system positioned about the area.

2. The system of claim 1, wherein to determine characteristics comprises:

identifying an object within the area based on the depth data; and

determining a relative location of the object based on depth detection.

3. The system of claim 2, wherein the relative location of the object is referenced to a component of the audio system and at least one of the plurality of speakers of the audio system.

4. The system of claim 3, wherein the relative location of the object is used to produce an area layout;

and

wherein the area layout is used to implement the sound profile for the area.

5. The system claim 4, wherein to configure audio output to a plurality of speakers of an audio system comprises providing audio output according to the sound profile.

6. The system of claim 1, wherein:

the sensor is a camera;

the camera captures an image including depth data; and

to determine characteristics comprises identifying an object represented within an image.

7. The system of claim 6, wherein to determine characteristics comprises:

accessing a database to obtain a pre-determined characteristic associated with an object identified in the area based on the image.

8. The system claim 1, wherein to provide audio output to a plurality of speakers of an audio system based on the characteristics comprises adjusting timing of the output to the plurality of speakers.

9. The system of claim 1, wherein to provide audio output to a plurality of speakers comprises configuring an audio output characteristic selected from the group consisting of amplitude, frequency, and balance.

10. The system of claim 1, wherein the sensor is selected from the group consisting of a camera that captures visual images, an image capture device that captures non-visible light, an image capture device that detects reflected light, and a single device that sends and receives acoustic energy.

11. A method, comprising:

capturing, using a sensor, depth data related to at least one position within an area;

identifying, using the processor, one or more user listening positions within the area using the depth data, wherein the user listening positions are identified based upon object locations within the area;

determining, using a processor, characteristics associated with the one or more user listening positions based on the depth data;

generating, based upon the determined characteristics, a sound profile of the area; and

configuring, using a processor and based on the sound profile, audio output to a plurality of speakers of an audio system positioned about the area.

12. The method of claim 11, wherein determining characteristics comprises:

identifying an object within the area based on the depth data; and

determining a relative location of the object based on depth detection.

13. The method of claim 12, wherein the relative location of the object is referenced to a component of the audio system and at least one of the plurality of speakers of the audio system.

14. The method of claim 13, wherein the relative location of the object is used to produce an area layout;

and

wherein the area layout is used to implement the sound profile for the area.

15. The method claim 14, wherein configuring audio output to a plurality of speakers of an audio system comprises providing audio output according to the sound profile.

16. The method of claim 11, wherein:

the sensor is a camera;

the camera captures an image including depth data; and

determining characteristics comprises identifying an object represented within an image.

17. The method of claim 16, wherein determining characteristics comprises:

accessing a database to obtain a pre-determined characteristic associated with an object identified in the area based on the image.

18. The method claim 11, wherein providing audio output to a plurality of speakers of an audio system based on the characteristics comprises adjusting timing of the output to the plurality of speakers.

19. The method of claim 11, wherein providing audio output to one or more speakers comprises providing an audio output characteristic selected from the group consisting of amplitude, frequency, and balance.

20. A computer program product, comprising:

a computer readable storage device having program executable code embodied therewith, the code being executable by a processor and comprising;

code that captures, using a sensor, depth data related to at least one position within an area;

code that identifies one or more user listening positions within the area using the depth data, wherein the user listening positions are identified based upon object locations within the area;

code that determines, using a processor, characteristics associated with the one or more user listening positions based on the depth data;

code that generates, based upon the determined characteristics, a sound profile for the area; and

code that configures, based on the sound profile, audio output to a plurality of speakers of an audio system positioned about the area.
