中文说明：最终的权值矩阵就是滤波器的系数，音频信号通过LM386放大，部分实现了追踪测速迭代松弛算法，计算多重分形非趋势波动分析，解耦，恢复原信号，正确率可以达到98％。
English Description：
Final weight matrix is that of the filter coefficients, the audio signal by LM386 amplifier, part of the implementation of the tracking velocimetry iterative relaxation algorithm, calculation of the multi fractal detrended fluctuation analysis, decoupling, recovery of the original signal, the correct rate can reach 98%.
