Abstract: An apparatus including a microphone, a speaker, and a processor. The speaker is configured to produce a sound that audibly communicates information to a user. The microphone is configured to receive the sound. The processor is configured to produce the sound through the speaker to audibly communicate information to the user; capture a video that includes audio; initiate a sound removal process to remove the sound from the audio; and after the sound is produced, stop the sound removal process.

Abstract: An image capture device detects a wind whistle using two or more microphones. The image capture device includes a processor that obtains microphone signals from the two or more microphones and determines coherence values between the microphone signals across a frequency band. The processor determines a coherence value for each frequency bin of the frequency band. Based on a detection of an elevated coherence value in a frequency bin, the processor determines the presence of a whistle. The processor attenuates the frequency bin based on a determination that the elevated coherence value is above a threshold.

Abstract: An image capture device may capture multiple audio content during capture of visual content. A viewing window for the visual content and rotational position of the image capture device during capture of the visual content may be used to generate modified audio content from the multiple audio content. The modified audio content may provide sound for playback of a punchout of the visual content using the viewing window.

Abstract: Wind processing performance is improved by the placement of one or more microphones on a device. The device includes one or more microphones on the front surface, one or more microphones on the top surface, and one or more microphones on the rear surface. The rear surface is a heatsink, and the one or more microphones on the rear surface are located in recesses created by two or more fins of the heatsink. The device includes a processor that performs wind processing based on signals from the one or more microphones on the front surface, signals from the one or more microphones on the top surface, signals from the one or more microphones on the rear surface, or any combination thereof.

Abstract: A handheld image stabilization device or an image capture device includes a housing, a motor, a microphone, and a dampener. The housing includes a first port. The motor is attached to the housing. The microphone detects audio waves via the first port and vibration noise of the motor via the housing. The audio waves may include acoustic noise from the motor. The dampener is coupled to the housing. The dampener reduces the acoustic noise from the motor and the vibration noise from the motor.

Abstract: An audio capture device selects between multiple microphones to generate an output audio signal depending on detected conditions. The audio capture device determines whether one or more microphones are wet or dry and selects one or more audio signals from the one or more microphones depending on their respective conditions. The audio capture device generates a mono audio output signal or a stereo output signal depending on the respective conditions of the one or more microphones.

Abstract: An image capture device, having: a housing, a lens snout, a front microphone, a top microphone, and an audio processor. The housing has a top and front housing surface. The lens snout protrudes from the front housing surface. The front microphone mounted within or on the front housing surface and below the lens snout. The top microphone mounted within or on a top housing surface in a position biased toward the front housing surface. The audio processor comprises a memory that is configured to store instructions that when executed cause the audio processor to generate an output audio signal. The top microphone is located at a position to receive direct freestream air flow when the housing is positioned in a pitched forward orientation at a pitched forward angle relative to a vertical axis. The front microphone receives turbulent air flow from the lens snout when the housing is positioned in the pitched forward orientation.

Abstract: An image capture device with dynamic wind noise compression tuning techniques is described. A technique includes detecting of the presence of wind noise by measuring coherence between at least two microphones. For a compressor, adjusting a default compression threshold and default compression parameters based on the coherence measurements. For each microphone, applying by the compressor the adjusted compression parameters when an audio signal is above the adjusted compression threshold and applying the default compression parameters when the audio signal is below the adjusted compression threshold.
