Abstract
A noise processing device and its method are provided for a video/audio system having a high definition multimedia interface (HDMI). The noise processing device includes a detecting unit, a signal generating unit, and a decision unit. The noise processing method includes using the detecting unit to monitor a variation related to an audio signal and generate a detecting signal accordingly; using the signal generating unit to produce an adjustment signal according to the detecting signal; and using the decision unit to produce an output audio signal according to the audio signal and the adjustment signal. Another embodiment of the noise processing device includes a compensation tracking unit having a control unit. The compensation tracking unit produces an output audio signal according to a difference between the output audio signal itself and the audio signal and a gain of the control unit.
