Abstract: The present disclosure relates to processing a plurality of audio signals. A device receives the plurality of audio signals in the frequency domain and determining an overall attenuation multiplier based on the plurality of audio signals and an overall lookup table that relates decibel values to different overall attenuation multipliers. The device determines an attenuation vector comprising a plurality of bin-specific attenuation multipliers, each bin-specific attenuation multiplier respectively corresponding to a different frequency bin of the plurality of frequency bins. The device scales each bin-specific attenuation value in the attenuation vector with the overall attenuation multiplier, and edits each of the audio signals based on the scaled bin-specific attenuation values in the attenuation vector.

Abstract: An image capture device and a handheld image stabilization device may each include a housing, a motor assembly, a microphone, a dampener, or any combination thereof. The housing may include a first port. The motor assembly may be attached to the housing. The motor assembly may include a plurality of motors. The microphone may be configured to detect audio waves via the first port, vibration noise of the plurality of motors via the housing, or both. The audio waves may include acoustic noise from the plurality of motors. The dampener may be coupled to the housing. The dampener may be configured to reduce the acoustic noise from the plurality of motors, the vibration noise from the plurality of motors, or both.

Abstract: Protected microphone systems may include one or more dampeners, one or more cavities, 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.
