Musical noise generation analysis for noise reduction methods based on spectral subtraction and MMSE STSA estimation

In this paper, we reveal new findings about the generated musical noise in minimum mean-square error short-time spectral amplitude (MMSE STSA) processing. Recently we have proposed a objective metric of musical noise based on kurtosis change ratio on spectral subtraction (SS). Also we found an inter...
