Abstract
A recording device comprising, a wind pressure sensor either foraged integral with the microphone or disposed at the vicinity of the microphone and detecting the wind pressure acting thereon; a recording circuit; a filter circuit which cuts off low sound components corresponding to the wind sound; a selection circuit which sends out the sound signal collected by the microphone to the recording circuit via the filter circuit in response to a control signal and, when no control signal is received, sends out the sound signal to the recording circuit while bypassing the filter circuit; and a control circuit which generates the control signal when the signal from the wind pressure sensor exceeds a predetermined level.
