Abstract
An audio processing method includes: converting a time-domain audio signal into a frequency-domain audio signal; determining a noise reduction gain according to the frequency-domain audio signal; and selecting at least one set of time-domain filter coefficients from a plurality sets of time-domain filter coefficients according to the noise reduction gain; configuring a time-domain filter according to the at least one selected set of time-domain filter coefficients, and filtering the time-domain audio signal with the time-domain filter.
