Based on the spectrum of the vuvuzela sound, this denoising technique simply computes an antenuation map in the time-frequency domain. Then, the audio signal is restored by computing the inverse STFT. See [1] or [2] for more detail about the algorith

这是在MATLAB上的DUET算法,实现欠定盲源分离。(This is a simulation of DUET Algorithm on MATLAB.
* Although the inverse STFT function doesn't work properly, the rest of it works totally fine.
* Fixed by moving the line: row=zeros(1,length(x1)+2*windowsize);)
