A computing device may maintain a database of representative spectral characteristics. The computing device may also receive particular spectral data associated with a particular playback environment corresponding to the particular playback device. Based on the particular spectral data, the computing device may identify one of the representative spectral characteristics from the database that substantially matches the particular spectral data, and then identify, in the database, an audio processing algorithm based on a) the identified representative spectral characteristic and b) at least one characteristic of the particular playback device. The computing device may then transmit, to the particular playback device, data indicating the identified audio processing algorithm.

A method of augmenting an ambiently experienced audio content is provided, the method comprises recording an acoustic audio signal from the ambiently experienced audio content; receiving a wireless signal comprising a first audio signal and a second audio signal, the wireless signal received using a first wireless communication system, wherein the first audio signal comprises sound that is also audible within the ambiently experienced audio content and the second audio signal comprises sound that is substantially inaudible within the ambiently experienced audio content; comparing the first audio signal with the acoustic audio signal to determine a delay between the acoustic audio signal and the first audio signal; delaying the second audio signal by the determined delay; and reproducing the delayed second audio signal at an audible volume, such that it is substantially synchronized with the ambiently experienced audio content. A device and system for augmenting the ambiently experienced audio content are also provided.

An audio system is provided that efficiently detects speaker arrays and configures the speaker arrays to output sound. In this system, a computing device may record the addresses and/or types of speaker arrays on a shared network while a camera captures video of a listening area, including the speaker arrays. The captured video may be analyzed to determine the location of the speaker arrays, one or more users, and/or the audio source in the listening area. While capturing the video, the speaker arrays may be driven to sequentially emit a series of test sounds into the listening area and a user may be prompted to select which speaker arrays in the captured video emitted each of the test sounds. Based on these inputs from the user, the computing device may determine an association between the speaker arrays on the shared network and the speaker arrays in the captured video.

A signal from a sensor may be received indicative of an acceleration of a moving component of a transducer at a location where the sensor is mounted. A position the moving component may be determined based on the acceleration. The position of the moving component may be compared with a reference to output a measure of distortion associated with the transducer. Nonlinearities in audio output by the transducer may be corrected based on the measure of distortion.

Presented herein is a hearing aid device that is configured to implement a frequency band bundling scheme and a method of processing an input audio signal.

Systems and processes for compensating for changes in a theatre sound system positioned in a theatre are described. A subsequent response of a loudspeaker to a test signal is captured and compared to a previously obtained signature response of the loudspeaker to the test signal. An audio signal can be processed based on the comparison to compensate for changes to loudspeaker performance, or otherwise.

An example implementation may involve a control device displaying a prompt to initiate a calibration sequence that involves calibration of a playback device for a given environment in which the playback device is located. The example implementation may also involve the control device displaying (i) a prompt to prepare a playback device for calibration within a given environment, (ii) a prompt to prepare the given environment for calibration of the playback device, and/or (iii) a prompt to prepare the control device for calibration of the playback device. The example implementation may also involve a control device displaying a selectable control, that, when selected, initiates calibration of the playback device. The example implementation may further involve a control device initiating calibration of the playback device.

VoIP telephone systems and methods are provided for use in a noisy listening environment. The systems and methods provide high quality voice broadcast into the noisy listening environment through independent voice channels which makes it easier for the human brain to discern broadcast words from the background noise.

A system and method for performing sound quality testing of audio equipment in a conference room is provided, wherein the method can executed by one or more processors, the audio equipment comprising one or more loudspeakers, one or more microphones, and audio signal processing equipment that includes at least an acoustic echo cancellation function, the method comprising: (a) determining an initial audio performance level (IAPL) of the audio equipment with the acoustic echo cancellation function disabled at a time t1; (b) determining a current audio performance level (CAPL) of the audio equipment with the acoustic echo cancellation function disabled at a second time, t2, which occurs after the first time t1; (c) comparing the CAPL to the IAPL; (d) determining if the audio equipment in the conference room passes or fails a sound quality test based on the comparison of the CAPL to the IAPL; and (e) providing the determination of pass or fail of the sound quality test to a remote user at a remote location through a cloud network.
