Abstract

Systems and methods for output of audio content are disclosed. An example first playback device includes a processor. The example processor is configured to at least process audio content to determine a portion of the audio content to be output by the first playback device based on a type of pairing of the first playback device and the audio content. The example processor is configured to at least determine, when the type of pairing pairs the first playback device with a second playback device to output the audio content, a time delay to facilitate sound synchronization with the second playback device. The example processor is configured to at least configure, based on the type of pairing and the time delay, the first playback device to output the portion of the audio content via an amplifier and a plurality of speaker drivers.

Claims

1. A first playback device comprising:

a network interface configured to receive audio data over a network;

a plurality of speaker drivers;

one or more amplifiers to power the plurality of speaker drivers;

one or more processors; and

tangible, non-transitory, computer readable memory comprising instructions encoded therein, wherein the instructions, when executed by the one or more processors, cause the first playback device to;

(i) process the audio data before the first playback device outputs audio from the plurality of speaker drivers;

(ii) determine that a type of pairing of the first playback device comprises one of at least a first type of pairing or a second type of pairing, wherein the first type of pairing comprises pairing with a second playback device and the second type of pairing comprises pairing with a plurality of playback devices;

(iii) determine a portion of the audio data to be output by the first playback device based on the determined type of pairing of the first playback device and the audio data;

(iv) when the determined type of pairing is the first type of pairing, determine a first time delay to facilitate sound synchronization with the second playback device;

(v) when the determined type of pairing is the second type of pairing, determine a second time delay to facilitate sound synchronization with the plurality of playback devices; and

(vi) configure, based on the determined type of pairing and the one of either the first determined time delay or the second determined time delay, the first playback device to output the determined portion of the audio data via the one or more amplifiers and the plurality of speaker drivers.

2. The first playback device of claim 1, wherein the instructions, when executed by the one or more processors, further cause the first playback device to:

determine a second portion of the audio data to be output by the second playback device.

3. The first playback device of claim 2, wherein the instructions, when executed by the one or more processors, further cause the first playback device to:

transmit the second portion of the audio data and the determined first time delay to the second playback device via the network interface.

4. The first playback device of claim 1, wherein the first type of pairing further comprises pairing with a third playback device.

5. The first playback device of claim 1, wherein the first type of pairing further comprises at least one of a) outputting at least two channel sound via the first playback device orb) outputting no more than one channel of the two channel sound via the first playback device.

6. The first playback device of claim 1, wherein the first type of pairing further comprises outputting the audio data via the first playback device when in consolidated mode.

7. The first playback device of claim 1, wherein the instructions, when executed by the one or more processors, further cause the first playback device to:

receive, from a controller, a selection of the portion of the audio data to be output by the first playback device.

8. The first playback device of claim 1, wherein the instructions, when executed by the one or more processors, further cause the first playback device to:

apply an equalization to the first playback device based on the determined type of pairing.

9. The first playback device of claim 1, wherein the first playback device further comprises a user interface for configuration of the type of pairing for the first playback device.

10. A method comprising:

receiving, at a first playback device, audio data over a network;

processing, at the first playback device, the audio data before the first playback device outputs audio from a plurality of speaker drivers;

determining that a type of pairing of the first playback device comprises one of at least a first type of pairing or a second type of pairing, wherein the first type of pairing comprises pairing with a second playback device and the second type of pairing comprises pairing with a plurality of playback devices;

determining a portion of the audio data to be output by the first playback device based on the determined type of pairing of the first playback device and the audio data;

determining, when the determined type of pairing is the first type of pairing, a first time delay to facilitate sound synchronization with the second playback device;

when the determined type of pairing is the second type of pairing, determining a second time delay to facilitate sound synchronization with the plurality of playback devices; and

configuring, based on the determined type of pairing and the one of either the first determined time delay or the second determined time delay, the first playback device to output the determined portion of the audio data.

11. The method of claim 10, further comprising:

determining a second portion of the audio data to be output by the second playback device.

12. The method of claim 11, further comprising:

transmitting the second portion of the audio data and the determined first time delay to the second playback device.

13. The method of claim 10, wherein the first type of pairing further comprises pairing with a third playback device.

14. The method of claim 10, wherein the first type of pairing further comprises at least one of a) outputting at least two channel sound via the first playback device or b) outputting no more than one channel of the two channel sound via the first playback device.

15. The method of claim 10, wherein the first type of pairing further comprises outputting the audio data via the first playback device when in consolidated mode.

16. The method of claim 10, further comprising:

receiving, from a controller, a selection of the portion of the audio data to be output by the first playback device.

17. The method of claim 10, further comprising:

applying an equalization to the first playback device based on the determined type of pairing.

18. The method of claim 10, further comprising:

facilitating, via a user interface of the first playback device, configuration of the type of pairing for the first playback device.

19. A tangible, non-transitory computer readable medium including instructions to be executed by a processor, the instructions, when executed, specially configuring the processor to implement a method comprising:

receiving audio data over a network at a first playback device having a plurality of speaker drivers;

processing the audio data before the first playback device outputs audio from the plurality of speaker drivers;

determining that a type of pairing of the first playback device comprises one of at least a first type of pairing or a second type of pairing, wherein the first type of pairing comprises pairing with a second playback device, and the second type of pairing comprises pairing with a plurality of playback devices;
