  • Apparatus and method of multi-sensor sound recording
    Patent number: 9407231
    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.

  • Electronic device and gain controlling method
    Patent number: 9349385
    Abstract: An electronic device and a corresponding gain controlling method are provided. The gain controlling method includes the steps of receiving a sound signal, calculating a sound level according to each value of the sound signal in a past period, determining a gain value according to the sound level, using the gain value to amplify the sound signal, and then storing the sound signal.
