Abstract
An apparatus and a method for sound recording are provided. The apparatus stores an equalizer and includes a housing, a microphone, and a processor. The microphone includes a plurality of sensors and receives a sound signal through an acoustical resonator in the housing. The microphone generates a plurality of electronic signals in response to the sound signal. The equalizer generates a plurality of equalized signals according to the electronic signals. The processor generates an output signal according to the equalized signals. The equalizer compensates the gain margin and the phase margin caused by the sound signal passing through the acoustical resonator in order to prevent the output signal from being affected by resonance of the sound signal in the acoustical resonator.
