I am looking for simple discrete wavelet transform source code for audio file in matlab. Can anyone tell me where can i find it?

问题回答

离散波段的转变可适用于任何信号,因此,您可使用<代码>wavedec或dwt功能,使用图像处理工具箱:

wname =  haar 
[y Fs] = wavread( filename.wav );
[C L] = wavedec(y, 1, wname);
wavplay(C(1:L(1)),Fs/2)

You will hear your audio sample low-pass filtrated and downsampled
