Audio Signal Processing Method Based on AGC Algorithm and its FPGA Implementation

In the speech communication system, the interference in receiving speech and audio information and other sources of instability factors need to be overcome for accurate and clear voice information. This paper studies the audio signal processing method based on AGC algorithm and its FPGA realization, and sums up the audio signal processing method based on practical AGC algorithm and FPGA implementations, which can reduce the degree of distortion of the audio signal, and significantly increase the stability of the audio signal output. Experimental results show that the application of AGC algorithm in audio signal processing and FPGA implementations offer good perform- ance.
