摘要
Abstract
Acoustic echo canceller has being an indispensable component of video conferencing system.An improved method of real-time audio processing system is proposed in combination with echo cancellation, noise cancellation and voice activity detection.The system based on TMS320C6713B DSP chip, and improved the problems of noise, double-talk detection,nonlinear echo and other problems leading to divergent adaptive filter.The system can ensure normal double-talk, and has significantly improved results of non-linear echo suppression.关键词
