Abstract: A camera system includes a first microphone, a second microphone, and a microphone controller. The first microphone and the second microphone are configured to capture audio over a time interval to produce a first captured audio signal and a second captured audio signal, respectively. The second captured audio signal is dampened relative to the first captured audio signal by a dampening factor. The microphone controller is configured to store the first captured audio signal in response to a determination that the first captured audio signal does not clip. In response to a determination that the first captured audio signal clips, the microphone controller is configured to identify a gain between the first captured audio signal and the second captured audio signal representative of the dampening factor, amplify the second captured audio signal based on the identified gain, and store the amplified second captured audio signal.

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.

Abstract: A camera includes a first microphone, a second microphone, one or more drains, and a processor. The processor determines a correlation metric between portions of audio signals obtained from the first and second microphones. The one or more drains drain water away from the first microphone, the second microphone, or both. The camera includes a memory to store the portions of the audio signals as portions of an output audio signal.

Abstract: An image capture device with beamforming for wind noise optimized microphone placements is described. The image capture device includes a front facing microphone configured to capture an audio signal. The front facing microphone co-located with at least one optical component. The image capture device further includes at least one non-front facing microphone configured to capture an audio signal. The image capture device further includes a processor configured to generate a forward facing beam using the audio signal captured by the front facing microphone and the audio signal captured by the at least one non-front facing microphone, generate an omni beam using the audio signal captured by the at least one non-front facing microphone, and output an audio signal based on the forward facing beam and the omni beam.

Abstract: A handheld image stabilization device with a housing, a gimbal, a motor, a printed circuit board (PCB), a microphone, and a dampener. The gimbal has three arms. The motor assembly has multiple motors such that respective ones of the multiple motors are located on respective ones of the three arms. The microphone is attached to a surface of the PCB and configured to detect audio waves, wherein the audio waves include acoustic noise from the motor assembly. The dampener is disposed between the motor assembly and the PCB, wherein the dampener is configured to reduce the acoustic noise from the motor assembly.

Abstract: An image capture device includes a housing, a processor, and three or more microphones. The housing includes a forward wall including a sensor, a rearward wall located opposite the forward wall, and a top wall connecting the forward wall and the rearward wall. The three or more microphones are configured to capture sound. The three or more microphones include a first microphone, a second microphone, and a third microphone. The processor is configured to receive the sound from the three or more microphones and to estimate a direction of arrival, reduce or remove wind noise, perform beamforming, or a combination thereof. The first microphone is located on or within the forward wall, the second microphone is located on or within the top wall, and the third microphone is located on or within the top wall and spaced apart from the second microphone.

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.
