传统双话筒降噪应用中，要求采用定向话筒对抗话音串扰问题，并且语音损伤较大，采用抗交叉串绕算法后，，仅噪声被抵消，语音信号被保留。分为两个阶段，第一阶段，学习环境，第二阶段，抵消噪声。

-The application of the traditional dual-microphone noise reduction, directional microphone to confront the problem of voice crosstalk, and the voice more damage with anti-cross-crosstalk algorithm, the only noise is offset, the voice signal is retained. Divided into two phases, the first phase, the learning environment, the second phase, offset and noise.
