[Speech/Voice recognition/combine] matlab_reduce_noise

Description: matlab去除50hz噪声。我用电脑录了一段声音，里面有50hz的周期噪声（因为受交流电干扰）。而我自己的声音频率最低是90hz。我使用了一个10阶butterworth高通滤波器，边带是70hz(介于50跟90之间)。问题是，这不能直接用。因为声音文件的采样率是22k，70相对于22k来说太小了。所以我得先把我的声音欠采样，然后再滤波，然后再插值。-matlab remove 50hz noise. I used the computer recorded a voice, there are 50hz cycle noise (due to AC interference). I own voice is the lowest frequency of 90hz. I use a 10-order Butterworth high-pass filter, edge belt is 70hz (the range between 50 to 90). The problem is that this can not be directly used. Because the sound files of the sampling rate is 22k, 70 compared with the 22k run too small. So I have to put my voice due to sampling, and then filtering, and then interpolation.
