Abstract: A camera is configured with multiple microphones to reduce wind noise in audio data collected by the camera. The camera receives motion data, which may comprise data indicating acceleration of the camera, a plurality of video frames received by the camera, or a background level of noise associated with one or more microphones configured on the camera. The camera determines a motion vector from the motion data. The motion vector is parallel to the direction of motion of the camera. The camera selects a subset of one or more microphones in the direction of the motion vector. By recording audio data using the one or more selected microphones, the camera reduces wind noise in the audio data.

Abstract: An audio capture device selects between multiple microphones to generate an output audio signal depending on detected conditions. When the presence of wind noise or other uncorrelated noise is detected, the audio capture device selects, for each of a plurality of different frequency sub-bands, an audio signal having the lowest noise and combines the selected frequency sub-bands signals to generate an output audio signal. When wind noise or other uncorrelated noise is not detected, the audio capture device determines whether each of a plurality of microphones are wet or dry and selects one or more audio signals from the microphones depending on their respective conditions.

Abstract: An audio capture system for a sports camera includes at least one “enhanced” microphone and at least one “reference” microphone. The enhanced microphone includes a drainage enhancement feature to enable water to drain from the microphone more quickly than the reference microphone. A microphone selection controller selects between the microphones based on a microphone selection algorithm to enable high quality in conditions where the sports camera transitions in and out of water during activities such as surfing, water skiing, swimming, or other wet environments.

Abstract: An image capture device reduces noise floor using multiple microphones. The image capture device includes a processor that obtains a front microphone signal from a front microphone, the front microphone signal having a noisy noise floor portion, obtains a rear microphone signal from a rear microphone, sets a splice point based on mitigation of the noisy noise floor portion relative to a speech frequency range, and combines a substantially clean noise floor portion of the rear microphone signal at or below the splice point with a remaining portion of the front microphone signal above the splice point to generate a microphone signal.

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: An image capture device may capture multiple audio content during capture of visual content. The field of view 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 the visual content with the field of view.

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: An apparatus including a microphone, a speaker, and a processor. The speaker is configured to produce a sound that indicates an image capture device including the microphone is recording. The microphone is configured to receive the sound. The processor is configured to initiate a sound removal process to remove the sound, produce the sound through the speaker to indicate that the image capture device is recording a video that includes audio, and, after the sound is produced, stop the sound removal process.
