Abstract

A method and system for compensating a frequency response of a microphone array are provided. The method includes: multiple microphones in a microphone array respectively receiving a compensation signal sent from a calibration speaker and outputting multiple output signals respectively (210); determining a uniform frequency response of the multiple microphones based on the multiple output signals (220); calculating a compensation gain for each of the multiple microphones according to the uniform frequency response (230); and storing the calculated compensation gain of each microphone (240).
