webrtc 的回声抵消(aec、aecm)算法主要包括以下几个重要模块：1.回声时延估计 2.NLMS(归一化最小均方自适应算法) 3.NLP（非线性滤波） 4.CNG(舒适噪声产生），一般经典aec算法还应包括双端检测(DT)。考虑到webrtc使用的NLMS、NLP和CNG都属于经典算法范畴，故只做简略介绍，本文重点介绍webrtc的回声时延估计算法,这也是webrtc回声抵消算法区别一般算法(如视频会议中的算法)比较有特色的地方。-webrtc echo canceller (aec, aecm) algorithm includes the following important modules: 1 echo delay estimation 2.NLMS (normalized least mean square adaptive algorithm) 3.NLP (nonlinear filtering) 4.CNG ( comfort noise generation), usually classical aec algorithm should also include double end detector (DT). Taking into account the NLMS webrtc use, NLP and CNG belong to the category of classical algorithms, it is only a brief introduction, this article focuses on the echo time delay estimation algorithm webrtc, which is the difference between general webrtc echo cancellation algorithm algorithm (such as video conferencing in the algorithm) compare interesting places.
