Research on algorithm of audio level compressor

A audio compressor is an important part of a audio processing system. The compression algorithm designed in this paper will be applied to audio compressor in the digital audio broadcasting transmitter. In this paper, an effective algorithm for dynamic control of the gain by taking mean square value is proposed, and two different audio signal from two channel processing schemes will be compared to get better one on the impact of compression. Then the algorithm is evaluated by the effect of compression of signal amplitude in the MATLAB simulation, and a scheme selected that signal is firstly dealt with to enhance the effect of the dual channel stereo and then is compressed is more suitable for the two channel audio compression from two schemes.
