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: An image capture device performs audio processing based on a detection of whether a wind sock is attached to the image capture device. When a wind sock is detected, the image capture device performs stereo processing. When a wind sock is not detected, the image capture device performs wind processing.

Abstract: An image capture device may capture multiple audio content during capture of visual content. A viewing window for the visual content and rotational position of the image capture device during capture 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 a punchout of the visual content using the viewing window.
