Methods and systems for suppressing noise

Abstract

The present invention relates to a suppressing noise system applied in a mobile device, comprises: at least two microphones are used for respectively transmitting a first audio signal with noise and a second audio signal with noise; a pre-processing unit is coupled to the at least two microphones for oversampling the first and second audio signals, downsampling the sampled first and second audio signals, and then generating a first adjusted signal and a second adjusted signal; and a suppressing noise device is coupled to the pre-processing device for filtering noise in the first and second adjusted signals once again, and outputting a third audio signal.
