Abstract: A system for enhancing audio including a plurality of sensors, an output device, and a processor in communication with the plurality of sensors and the output device. The processor is configured to process data captured by the plurality of sensors, and based on that, modify an output of the output device. The processor also is configured to determine whether there are a plurality of users associated with a video conferencing session, determine which user of the plurality of users is speaking, and enhance the audio or video output of the speaking user on the output device.

Abstract: Examples described herein involve validating motion of a microphone during calibration of a playback device. An example implementation involves a mobile device detecting, via one or more microphones, audio signals emitted from one or more playback devices as part of a calibration process. After the one or more playback devices emit the audio signals, the mobile device determines whether the detected audio signals indicate that sufficient horizontal translation of the mobile device occurred during the calibration process. When the detected audio signals indicate that insufficient horizontal translation occurred, the mobile device displays a prompt to move the mobile device more while the one or more playback devices emit one or more additional audio signals as part of the calibration process. When the detected audio signals indicate that sufficient horizontal translation occurred, the mobile device calibrates the one or more playback devices with a calibration based on the detected audio signals.

Abstract: A method for designing a loudspeaker excursion estimator comprises measuring an excursion-related parameter for a loudspeaker, for each of a plurality of loudspeaker input signal levels and each of a plurality of loudspeaker input signal frequencies. The method further comprises, for each of the loudspeaker input signal frequencies and based on the measured excursion-related parameters, identifying a respective loudspeaker input signal level corresponding to a target maximum excursion-related parameter value. The method further comprises determining a filter response, based on the identified loudspeaker input signal levels and their respective loudspeaker input signal frequencies, and implementing a filter, based on the calculated filter response, for generating an excursion estimation based on loudspeaker input signal levels.

Abstract: One example may include a method that includes initiating an audio recording to capture audio data, comparing the audio data received from a microphone of a mobile device to an audio data range, determining whether the audio data is above an optimal level based on a result of the comparison, and queuing the audio data in an audio data queue when the audio data is above the optimal level.

Abstract: A method performed by an in-ear headphone. Coupled to the in-ear headphone is a first ear tip that is inserted into an ear canal of a user. The method obtains an audio signal from an audio source device paired with the in-ear headphone and uses the signal to drive a speaker of the headphone to output a sound into the ear canal. The method obtains a microphone signal that is responsive to the outputted sound. The method notifies the user to replace the first ear tip with a second ear tip in response to a parameter associated with the microphone signal being less than a threshold.

Abstract: Example techniques involve a calibration state variable. An example implementation receives, via a network interface, an indication that the first playback device is calibrated. Based on receiving the indication that the first playback device is calibrated, the example implementation updates a calibration state variable to indicate that the first playback device is calibrated, wherein the calibration state variable is stored in the data storage. The example implementation sends, via the network interface, an indication of the updated calibration state variable to a second device.
