Audio output balancing
First Claim
1. A first playback device comprising:
- one or more processors; and
tangible, non-transitory computer-readable memory having stored thereon instructions that, when executed by the one or more processors, cause the first playback device to perform functions comprising;
receiving audio content to be played back by the first playback device and a second playback device in synchrony, wherein the audio content comprises a first stereo component to be played by the first playback device and a second stereo component to be played by a second playback device in synchrony with playback of the first stereo component by the first playback device;
determining a limiting result that represents playback of the first stereo component of the audio content by applying to the first stereo component of the audio content, a pre-determined volume-limiting function that is associated with the first playback device, wherein the limiting result indicates frequencies at which a playback volume of the first playback device is limited;
determining a crossover frequency based on the indicated frequencies at which the playback volume of the first playback device is limited;
causing the second playback device to play (i) the second stereo component of the audio content and (ii) a first portion of the first stereo component of the audio content that is below the crossover frequency; and
playing a second portion of the first stereo component of the audio content that is above the crossover frequency in synchrony with playback of the first portion of the first stereo component by the second playback device.

Abstract
Systems and method are provided herein for balancing of outputs from playback devices playing audio content in synchrony. In one embodiment, the balancing of outputs may involve receiving a first audio signal to be played by a first playback device according to a first crossover frequency, determining a limiting result by applying a limiting function associated with a second playback device to a second audio signal to be played by the second playback device according to a second crossover frequency, and based on the first limiting result, configuring the first playback device to play the first audio signal according to a third crossover frequency. In some cases, the first and second playback devices may be configured to play the first and second audio signals, respectively, in synchrony.

9. Tangible, non-transitory computer-readable memory having stored thereon instructions that, when executed by one or more processors of a first playback device, cause the first playback device to perform functions comprising:
-
receiving audio content to be played back by the first playback device and a second playback device in synchrony, wherein the audio content comprises a first stereo component to be played by the first playback device and a second stereo component to be played by a second playback device in synchrony with playback of the first stereo component by the first playback device; determining a limiting result that represents playback of the first stereo component of the audio content by applying to the first stereo component of the audio content, a pre-determined volume-limiting function that is associated with the first playback device, wherein the limiting result indicates frequencies at which a playback volume of the first playback device is limited; determining a crossover frequency based on the indicated frequencies at which the playback volume of the first playback device is limited; causing the second playback device to play (i) the second stereo component of the audio content and (ii) a first portion of the first stereo component of the audio content that is below the crossover frequency; and playing a second portion of the first stereo component of the audio content that is above the crossover frequency in synchrony with playback of the first portion of the first stereo component by the second playback device. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16)

17. A method comprising:
-
receiving by a first playback device, audio content to be played back by the first playback device and a second playback device in synchrony, wherein the audio content comprises a first stereo component to be played by the first playback device and a second stereo component to be played by a second playback device in synchrony with playback of the first stereo component by the first playback device; determining by the first playback device, a limiting result that represents playback of the first stereo component of the audio content by applying to the first stereo component of the audio content, a pre-determined volume-limiting function that is associated with the first playback device, wherein the limiting result indicates frequencies at which a playback volume of the first playback device is limited; determining by the first playback device, a crossover frequency based on the indicated frequencies at which the playback volume of the first playback device is limited; causing by the first playback device, the second playback device to play (i) the second stereo component of the audio content and (ii) a first portion of the first stereo component of the audio content that is below the crossover frequency; and playing by the first playback device, a second portion of the first stereo component of the audio content that is above the crossover frequency in synchrony with playback of the first portion of the first stereo component by the second playback device. - View Dependent Claims (18, 19, 20)
