The disclosure is generally directed to a system for reducing wind noise. A system includes one or more processors coupled to a non-transitory computer-readable storage medium having instructions encoded thereon that, when executed by the one or more processors, cause the one or more processors to obtain signals respectively generated from two or more microphones during a time period, the signals representing acoustic energy detected by the two or more microphones during the time period, determine a coherence between the signals, and determine a filter based on the coherence. The filter is configured to reduce wind noise in one or more of the signals.

Systems and methods for reducing wind noise

An audio device includes a speaker array and a controller for beam-steering audio output by the speaker array to localize sound in different locations in a local area around the audio device. The audio device also includes a microphone array or a set of cameras configured to detect an object, such as a human, in the local area around the audio device. From data captured by the microphone array or the set of cameras, the audio device determines a location of the object in the local area and steers the audio output by the speaker array towards the determined location of the object. As the object moves within the local area, the audio device dynamically steers the audio output to move along with the object.

Speaker beam-steering based on microphone array and depth camera assembly input

An audio device includes a speaker array and a controller for beam-steering audio output by the speaker array to localize sound in different locations in a local area around the audio device. The audio device also includes a microphone array or a set of cameras configured to detect an object, such as a human, in the local area around the audio device. Additionally, the audio device includes a subwoofer for outputting low frequencies. Different speakers are included in different chambers, with the subwoofer also included in a chamber. The audio device opens or closes valve doors separating adjacent chambers to alter audio output. Opening the valve doors allows the audio device to better output low frequencies, while closing the valve door allows the audio device to direct audio output by the speakers to locations in the local area.
