Publication number: 20170064453Abstract: 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.Type: ApplicationFiled: November 3, 2016Publication date: March 2, 2017Inventors: Aurelio Rafael Ramos, Timothy W.

Patent number: 9549258Abstract: An example implementation involves a first playback device receiving audio content to be played back by the first playback device and a second playback device in synchrony. Such audio content may include a first and second stereo component. The first playback device determines a limiting result that indicates frequencies at which a playback volume of the second playback device is limited and determines a crossover frequency based on the indicated frequencies at which the playback volume of the second playback device is limited. The first playback device causes the second playback device to play a first portion of the second stereo component that is above the determined crossover frequency and plays (i) the first stereo component and (ii) a second portion of the second stereo component that is below the indicated frequency in synchrony with playback of the first portion by the second playback device.Type: GrantFiled: April 21, 2016Date of Patent: January 17, 2017Assignee: Sonos, Inc.Inventors: Aurelio Rafael Ramos, Timothy W.

Patent number: 9544707Abstract: An example implementation involves a first playback device receiving audio content to be played back by the first playback device and a second playback device in synchrony. The audio content includes a first stereo component to be played by the first playback device and a second stereo component to be played by the second playback device. The first playback device determines a first limiting result that represents playback of the second stereo component by a second playback device by applying, to the second stereo component, a pre-determined volume-limiting function that is associated with the second playback device. The first playback device determines another volume-limiting function based on the first limiting result and applies the determined volume-limiting function to the first stereo component when playing the first stereo component in synchrony with the playback of the second stereo component by the second playback device.Type: GrantFiled: April 21, 2016Date of Patent: January 10, 2017Assignee: Sonos, Inc.Inventor: Aurelio Rafael Ramos

Publication number: 20160299737Abstract: An example playback device includes one or more processors and a non-transitory computer-readable medium storing instructions that, when executed by the one or more processors, cause the playback device to perform functions. The functions include receiving digital data representing audio content. The functions further include sending at least a portion of the digital data to an identification system configured to identify the audio content based on the at least a portion of the digital data. The functions further include receiving information associated with the audio content from the identification system. The functions further include, in response to receiving the information associated with the audio content from the identification system, sending the received information to a control device that is configured to control the playback device. The functions further include playing the audio content via one or more speakers electrically connected to the playback device via a wired connection.Type: ApplicationFiled: April 10, 2015Publication date: October 13, 2016Inventors: Eric Clayton, Aurelio Rafael Ramos
