Abstract

See full text

Systems and methods are provided for noise reduction. An input audio signal is received. A target gain corresponding to a target volume level is determined. One or more increments of gain change are determined to reach the target gain. A first non-zero amplitude in the input audio signal is detected. The first non-zero amplitude is not within a predetermined range of zero amplitude. Upon the detection of the first non-zero amplitude in the input audio signal, the one or more increments of gain change are applied at one or more zero-crossing points of the input audio signal. The input audio signal is within the predetermined range of zero amplitude at the one or more zero-crossing points. An output audio signal is generated.
