Patent number: 11947865Abstract: An example implementation involves a playback device receiving digital data representing audio content, the digital data encoded in a first format. The playback device causes one or more speaker drivers to playback the audio content. The playback device decodes a portion of the received digital data to convert the portion of the received digital data from the first format to a second format and transmits, via a network interface to a computing device of an identification system, the decoded portion of the received digital data. The playback device receives, from via the network interface from the identification system, metadata corresponding to the audio content, and in response, causes a control device to display a graphical representation of the received metadata, wherein causing the control device to display the graphical representation comprises sending, via the network interface to the control device, the received metadata to the control device.Type: GrantFiled: July 2, 2021Date of Patent: April 2, 2024Assignee: Sonos, Inc.Inventors: Eric Clayton, Aurelio Rafael Ramos

Publication number: 20230402982Abstract: Disclosed herein are example techniques to facilitate calibrating a portable playback device. An example implementation involves determining that a playback device is to perform an equalization calibration of the playback device and initiating the equalization calibration. Initiating the equalization calibration involves (i) outputting audio content, (ii) capturing audio data representing reflections of the audio content within an area in which the playback device is located, (iii) determining an acoustic response of the area in which the playback device is located, (iv) selecting a stored acoustic response from the acoustic response database that is most similar to the determined acoustic response of the area in which the playback device is located, and (v) applying to the audio content, via the playback device, a set of stored audio calibration settings associated with the selected stored acoustic area response.Type: ApplicationFiled: August 9, 2023Publication date: December 14, 2023Inventors: Patrick McPherson, Aurelio Rafael Ramos

Patent number: 11818558Abstract: Example techniques relate to audio generation in a media playback system. Based on one or more first functions and first characteristics of an area, the system may generate first audio that includes a first audio signal and a second audio signal. The system provides the first audio signal to at least one first audio driver and the second audio signal to at least one second audio driver, thereby causing a first playback device and a second playback device to play back the first audio synchronously. The system receives second characteristics of the area and based on one or more second functions and the second characteristics, generates second audio comprising a third audio signal and a fourth audio signal. The system provides the third audio signal to the at least one first audio driver and the fourth audio signal to the at least one second audio driver.Type: GrantFiled: October 7, 2022Date of Patent: November 14, 2023Assignee: Sonos, Inc.Inventors: Mike Chamness, Aurelio Rafael Ramos, Timothy Sheen, Hilmar Lehnert

Patent number: 10863273Abstract: An example method is performed by a media playback system comprising a plurality of audio drivers configured to output audio content according to a first radiation pattern that produces an inherent directional effect. Based on data representing positions of one or more listeners in a listening area, the system determines first and second transfer functions corresponding to the first and second audio drivers, respectively. One or both of the transfer functions configure the first and second audio drivers to output audio content according to a second radiation pattern that produces a modified directional effect relative to the first radiation pattern. The system applies the transfer function to audio content thereby causing the first and second audio drivers to play back audio content according to the second radiation pattern.Type: GrantFiled: July 8, 2019Date of Patent: December 8, 2020Assignee: Sonos, Inc.Inventors: Mike Chamness, Aurelio Rafael Ramos, Timothy Sheen, Hilmar Lehnert
