1. An audio denoising system, comprising:
at least one storage medium storing at least one set of instruction for audio denoising; and
at least one processor in communication with the at least one storage medium, wherein during operation, the at least one processor executes the set of instructions to:
obtain a to-be-processed audio signal,
obtain at least one modulation parameter related to a frequency of the to-be-processed audio signal, wherein the at least one modulation parameter at least includes a plurality of frequency units of the to-be-processed audio signal,
based on the at least one modulation parameter and a preset gain function, obtain at least one gain coefficient corresponding to the at least one modulation parameter, wherein the at least one gain coefficient is in a negative correlation with the plurality of frequency units,
perform gain processing on the to-be-processed audio signal based on the at least one gain coefficient corresponding to the at least one modulation parameter to obtain a target audio signal, and
output the target audio signal.
