AUDIO SIGNAL PROCESSING DEVICE

摘要

PROBLEM TO BE SOLVED: To prevent pressure fluctuation caused by turbulence generated by impingement of wind on a microphone surface in order to acquire an audio signal small in wind noise. SOLUTION: This audio signal processing device acquires an audio signal of a predetermined frequency lower than the resonance frequency of a shielding unit out of audio signals obtained by a first sound collecting unit shielded from influence of a flow of air outside the device by the shielding unit having a predetermined resonance frequency for shielding the first sound collecting unit from the influence of the flow of the air outside the device.
