摘要：
A method of processing an audio signal is provided. The method includes: acquiring an audio signal of a frequency domain for a plurality of frames; dividing a frequency band into a plurality of sections; acquiring energies of the plurality of sections; detecting an audio signal including noise based on an energy difference between the plurality of sections; and applying a suppression gain to the detected audio signal.
