I can see STFT working pretty well, see Fig.2.1, Chapter 2 and Fig 3.1, 3.3, 3.4 Chapter 3, of the book I mentioned above, and I'm sure there will be some mathematical justification as the mathematical theory (even for tempered distributions) is very well developed. | |

I think the STFT is a poor method for this type of thing mainly because of the time/frequency uncertainty and the whacky way transients are represented in the phase of the STFT. Hence I'm guessing it will be hard to find a mathematical justification for something that's unlikely to work well in the first place. | |
