Abstract :
The algorithm of the dynamic range control (DRC) was applied in the research of the audio directional system. According to the feature of audio directional system, the implementation of the static curve was modified, and the model of DRC based on simulink was built. The calculation results demonstrate that DRC is an effective optimal method to enhance the main sound and reduce the noise in the audio directional system.
