Sound is a multidimensional medium, the fundamental dimensions of sound are pitch, timbre, loudness, duration and direction, further more, sound has multiple effects, these effects roughly are cocktail party effect, streaming, echo and reverb
聲音是一種多維度媒體，主要有音調、音色、響度、持續時間和方向等維度特徵；聲音又是一種多效應媒體，主要有雞尾酒會效應、流效應和回聲、反射等效應特徵。 -
The implementation of such a system is extremely complicated due to three factors : the impulse response of a lrm system have a duration of several hundred milliseconds, the system has to be adaptive, and the adaptation has to be performed with a speech input the traditional adaptive algorithms such as lms and nlms can not obtain the satisfied result in the real - time acoustic echo cancellation processing
但由於聲回授通道的特殊性和復雜性，普通的自適應演算法無法滿足要求，必須採用一些十分復雜的演算法，這樣一來，實時性的問題變得十分突出。快速lms newton演算法的提出，給自適應聲回波對消問題的解決開辟了新的途徑。該演算法集lms演算法的簡單易行性和newton演算法的快收斂性為一體，是一種非常有應用前景的自適應演算法。
