Abstract: An audio system encodes and decodes audio captured by a microphone array system in the presence of wind noise. The encoder encodes the audio signal in a way that includes beamformed audio signal and a “hidden” representation of a non-beamformed audio signal. The hidden signal is produced by modulating the low frequency signal to a high frequency above the audible range. A decoder can then either output the beamformed audio signal or can use the hidden signal to generate a reduced wind noise audio signal that includes the non-beamformed audio in the low frequency range.
Abstract translation: 音频系统在存在风噪声的情况下对由麦克风阵列系统捕获的音频进行编码和解码。 编码器以包括波束形成的音频信号和非波束形成的音频信号的“隐藏”表示的方式对音频信号进行编码。 通过将低频信号调制到高于可听范围的高频产生隐藏信号。 然后，解码器可以输出波束形成的音频信号，或者可以使用隐藏信号来产生包括低频范围内的非波束成形音频的降低的风噪声音频信号。

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: A spherical content capture system captures spherical video and audio content. In one embodiment, captured metadata or video/audio processing is used to identify content relevant to a particular user based on time and location information. The platform can then generate an output video from one or more shared spherical content files relevant to the user. The output video may include a non-spherical reduced field of view such as those commonly associated with conventional camera systems. Particularly, relevant sub-frames having a reduced field of view may be extracted from each frame of spherical video to generate an output video that tracks a particular individual or object of interest. For each sub-frame, a corresponding portion of an audio track is generated that includes a directional audio signal having a directionality based on the selected sub-frame.
