摘要
This article discusses the development of a real-time software acoustic echo canceller (AEC) for personal computer (PC) applications. It proposes a method to reduce computation load by adaptively setting the length of the adaptive filter to match the end-system hardware-software configuration and the acoustic environment. Tests show that this method works stably with real speech signals, reducing echo by approximately 20 dB on average.
