这是一个很好的频域分块自适应滤波的程序，应用于回声消除上，并与NLMS自适应滤波做了运行速度的比较,FLMS比NLMS快几十倍。-This is a very good frequency-domain block adaptive filtering procedure applied to echo cancellation, and comparison with the NLMS adaptive filter for speed, FLMS several times faster t

改程序是本人在vs2008环境下编译通过的自适应滤波器的回声消除程序，运用了NLMS算法消除回声，效果还不错！-Change the program I compiled in vs2008 environment through the adaptive filter echo cancellation procedures, the use of the NLMS algorithm to eliminate echo, the results were pretty good!
