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: A camera includes a first microphone, a second microphone, and a processor. The processor determines a correlation metric between portions of audio signals obtained from the first and second microphones. The camera includes a memory to store the portions of the audio signals as portions of an output audio signal.

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 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: 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: A camera controller is configured to control a camera through voice commands. The camera controller includes drain mechanisms that allow the camera controller to be used in environments in which the camera controller is exposed to fluids. The camera controller device comprises a housing body with an outer surface including a first opening and a second opening. A first channel extends from the first opening into the housing body and to a cavity in which a microphone is located, enabling audio signals entering the first opening to be captured by the microphone. A membrane is located between the first channel and the microphone to create a waterproof seal over the microphone. A second channel extends from the first channel to the second opening to create a drain such that fluid entering from the first opening can flow from the first channel through the second channel and out the second opening.

Abstract: A camera system capable of capturing images of an event in a dynamic environment includes two microphones configured to capture stereo audio of the event. The microphones are on orthogonal surfaces of the camera system. Because the microphones are on orthogonal surfaces of the camera system, the camera body can impact the spatial response of the two recorded audio channels differently, leading to degraded stereo recreation if standard beam forming techniques are used. The camera system includes tuned beam forming techniques to generate multi-channel audio that more accurately recreates the stereo audio by compensating for the shape of the camera system and the orientation of microphones on the camera system. The tuned beam forming techniques include optimizing a set of beam forming parameters, as a function of frequency, based on the true spatial response of the recorded audio signals.
