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 translation: 用于运动照相机的音频捕获系统包括至少一个“增强”麦克风和至少一个“参考”麦克风。 增强型麦克风包括排水增强功能，使得水能够比参考麦克风更快地从麦克风中排出。 麦克风选择控制器基于麦克风选择算法在麦克风之间进行选择，以在诸如冲浪，滑水，游泳或其它湿润环境的活动期间在运动相机转入和移出水的条件下实现高质量。

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 one or more microphone pairs. A first microphone (e.g., a main microphone) is ported to the outside of the camera and captures the desired external audio signal, but may also capture undesired vibrational noise. A second microphone has a similar structure to the first microphone, but is not ported to the outside of the camera. Instead, the second microphone is ported into an enclosed cavity (e.g., 1-2 cubic centimeters in volume). The second microphone may pick up the same vibration excitation and internal acoustic noise as the first microphone but very little of the desired external acoustic sounds around the camera. The unwanted noise can then be removed by subtracting the second audio signal from the second microphone from the main audio signal from the main microphone.

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 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.
