Acoustic signal processing has been widely used in many fields. In order to meet the demand of engineering applications, a universal acoustic signal processing platform based on DSP+ARM has been proposed to realize acquisition, processing and output of two-channel acoustic signals. The hardware and software realization methods have been discussed. At the same time, the acoustic signal acquisition performance and impulse response of acoustic signal output module have been measured. The results show that the acquisition sensitivity is 86 mV/Pa, the output response is changed by different loudspeakers.
