Abstract:
An audio processor, comprising:a gain controller that receives an input signal, wherein the gain controller multiplies the input signal by a first predetermined value to control a size of the input signal;a signal processor that process a signal output by the gain controller and outputs a processed signal;a volume controller that multiplies the processed output signal of the signal processor by a second predetermined value to control a size of an output signal;a first comparator that compares the input signal and a previous input signal respectively received by the gain controller;a second comparator that compares the output signal and a previous output signal respectively output by the gain controller; anda noise gate that receives output signals from the first comparator and the second comparator, wherein the noise gate reduces a signal size of the output signal of the volume controller to a prescribed level based on the output signals of the first and second comparators.
