Abstract
Various embodiments of the present technology comprise a method and apparatus for a microphone system. Various embodiments of the present technology may comprise a first microphone connected to a first high pass filter and a second microphone connected to a second high pass filter. The microphone system may further comprise a frequency controller configured to selectively activate the first high pass filter and the second high pass filter according to detected wind noise. The first and second high pass filters may be arranged to filter sound data from the first and second microphone prior to processing the sound data using beamforming.
