| description | The invention discloses an audio signal processing device and an audio signal adjusting method thereof. The audio signal processing device includes a gain determination circuit and an audio signal processing circuit. The gain determination circuit receives an analog audio signal. In response to detecting that the current sampling amplitude of the analog audio signal is greater than a preset threshold, the gain determination circuit determines a gain value based on a difference between the preset threshold and the amplitude of the analog audio signal. The audio signal processing circuit is coupled to the gain determination circuit and receives the analog audio signal and the gain value. The audio signal processing circuit attenuates the analog audio signal according to the gain value to generate an output audio signal.
一种音频信号处理装置与其音频信号调整方法。音频信号处理装置包括增益决定电路以及音频信号处理电路。增益决定电路接收模拟音频信号。响应于检测到模拟音频信号的当前取样振幅大于预设临界值，增益决定电路基于预设临界值与模拟音频信号的振幅之间的差值决定增益值。音频信号处理电路耦接增益决定电路，并接收模拟音频信号与增益值。音频信号处理电路依据增益值衰减模拟音频信号而产生输出音频信号。 |
