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. 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: Protected microphone systems may include one or more dampeners, one or more protective layers, or a combination thereof to minimize the vibration sensitivity of a microphone of the protected microphone systems. The dampeners, when present, may be constructed of a foam material or a thin metal material. The protective layer may be a membrane, a mesh, or any suitable material. The protective layer may be air permeable or non-air permeable.

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 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 translation: 相机配置有多个麦克风，以减少相机收集的音频数据中的风噪声。 摄像机接收运动数据，其可以包括指示相机的加速度的数据，由相机接收的多个视频帧，或者与在相机上配置的一个或多个麦克风相关联的背景噪声水平。 相机从运动数据确定运动矢量。 运动矢量平行于摄像机的运动方向。 相机在运动矢量的方向上选择一个或多个麦克风的子集。 通过使用一个或多个所选择的麦克风记录音频数据，照相机降低音频数据中的风噪声。
