Abstract: In an audio denoising method and system provided in the present disclosure, a gain coefficient corresponding to each frequency unit may be generated based on a parameter related to a frequency by using a frequency of an audio signal as a unit, and gain processing is performed on each frequency unit separately by using the gain coefficient. The gain coefficient corresponding to a frequency unit including more valid audio signals may be larger, and a gain coefficient corresponding to a frequency unit including fewer valid audio signals may be smaller, so that more audio signals corresponding to frequency parts including more valid audio signals are preserved, while less audio signals corresponding to frequency parts including fewer valid audio signals are preserved. In this way, fidelity and intelligibility of an audio signal are improved while quality of the audio signal is improved and noise is reduced.
