...s the simplest consists in overestimating the noise power spectrum. In this case, musical noise reduction is a trade-off for the loss of valuable signal content, especially on the highfrequency range =-=[3]-=-. The total cancellation of the noise can only be obtained at the cost of some distortion of the low-level components. Within the class of non-parametric methods, the wavelet-based shrinkage is used. ...
