Abstract

A system (100) and method (400) for sharing an audio experience is provided. The method can include identifying (402) mobile devices (104) in an area (910), discovering (404) sound production capabilities and sound monitoring capabilities, identifying (406) a relative location of devices in the area, assessing room acoustics (706), and networking the (408) devices for creating a surround sound based on the relative location, sound capabilities, and room acoustics. The system can include a group of active devices to generate the surround sound, a group of passive devices to listen to the surround sound, and a master device to configure the delivery of audio media based on the surround sound analyzed by the passive devices

Claims

generating a surround sound from the plurality of devices in accordance with the delivery of audio,

wherein a master device assigns a first group of devices as active devices for generating the surround sound, and a second group of devices as passive devices for listening to the surround sound, and the master device configures the delivery of audio media to the active devices based on the surround sound analyzed by the passive devices.

2. The method of claim 1, wherein the networking further comprises:

discovering sound capabilities for the plurality of devices, wherein the sound capability identifies an audio bandwidth, a data processing capacity, a battery capacity, a speaker volume level, a mobility, or available resources.

3. The method of claim 2, wherein the configuring further comprises:

assigning audio channels to active devices based on the sound capability and the relative location; and

adding or removing devices in responses to a device entering or leaving the proximity.

4. The method of claim 1, wherein configuring a delivery of audio media further comprises:

listening to the surround sound by at least one passive device;

identifying audio nulls in the surround sound at a location; and

adjusting a delivery of audio to an active device, or converting a passive device to an active device for playing sound and filling in the audio nulls at the location.

5. The method of claim 1, wherein configuring a delivery of audio media further comprises:

listening to the surround sound by at least one passive device;

identifying audio redundancy in the surround sound at a location; and

adjust a delivery of audio to an active device, or converting an active device to a passive device for suppressing audio redundancy at the location.

6. The method of claim 1, wherein configuring a delivery of audio further comprises:

retrieving sound capabilities from the plurality of devices in a room;

assessing room acoustics of the room from the plurality of devices;

selecting devices to generate sound based on the sound capabilities; and

formatting the audio media for delivery to the plurality of devices based on the relative location, the sound capabilities and the room acoustics.

7. The method of claim 6, further comprising:

identifying a position of active devices in the room;

assigning audio channels to the active devices based on the position;

monitoring the active devices contributing to the surround sound;

updating a delivery of audio in accordance with sound capabilities of the active devices for maintaining a quality of the surround sound.

8. The method of claim 6, further comprising:

synchronizing the sound experience with another plurality of devices in another area.

9. The method of claim 1, wherein the passive devices analyze the surround sound by:

evaluating a volume level of the surround sound; and

reporting the volume level to the master device, wherein the master device equalizes the volume level across the plurality of devices, such that a volume of the surround sound is balanced in accordance with a specification of the audio media.

10. The method of claim 1, wherein the passive devices analyze the surround sound by:

evaluating a stereo distribution of the surround sound; and

reporting the stereo distribution to the master device, wherein the master device equalizes the stereo distribution across the plurality of devices, such that a stereo effect of the surround sound is distributed in accordance with a specification of the audio media.

11. A system for mobile disc jockey (DJ), comprising:

a plurality of devices for generating and monitoring a surround sound in an area; and

a master device for assigning devices as active devices or passive devices based on a relative location of the devices and a feedback quality of the surround sound,

wherein the master devices coordinates a delivery of audio to the plurality of devices for sharing an audio experience.

12. The system of claim 11, wherein the plurality of devices comprise:

a group of active devices in an area for generating the surround sound;

a group of listening devices in the area for listening to the surround sound, assessing room acoustics, and reporting a feedback quality of the surround sound,

wherein the master device identifies a relative location of the plurality of devices, classifies devices as active or passive based on a relative location of the devices, assigns an audio channel to active devices to produce a portion of the surround sound, and coordinates a delivery of audio media to the group of active devices based on the relative location and feedback quality from the passive devices.

wherein an active device, a listening device, and the master device perform interchangeable functions, such that an active device or passive can be configured as a active device or passive device and that can also be configured as a master device.

13. The system of claim 11, wherein a device comprises:

a device locator for;

identifying a relative location of active devices and listening devices in the area;

a controller for;

identifying a sound capability of an active device or listening device based on the relative location, and

a processor for;

formatting audio media based on the sound capability; and

adjusting a delivery of audio to the group of active devices in accordance with the relative location and a feedback quality from the group of listening devices,

wherein the sound capability identifies an audio bandwidth, a data processing capacity, or a speaker volume level.

14. The system of claim 11, wherein the controller further

determines whether a device is fixed or mobile;

and

determines when devices enter or leave the area.

15. The system of claim 11, wherein a device further includes:

a sound analyzer for analyzing room acoustics and the surround sound generated by the group of active devices, and reporting the room acoustics and a feedback quality of the surround sound to the master device.

16. The system of claim 12, wherein the processor:

assigns one of the mobile devices as an active device or as a listening device based on the relative location; and

configures a delivery of audio media to the active device by specifying a sound channel,
