Abstract

An audio signal processing device and an audio signal adjusting method thereof. The audio signal processing device includes a gain determining circuit and an audio signal processing circuit. The gain determining circuit receives an analog audio signal. The gain determining circuit determines a gain based on a difference between a predefined threshold and an amplitude of the analog audio signal in response to detecting that a current sampling amplitude of the analog audio signal is greater than the predefined threshold. The audio signal processing circuit is coupled to the gain determining circuit and receives the analog audio signal and the gain. The audio signal processing circuit attenuates the analog audio signal according to the gain to generate an output audio signal.
