#205 Wavelet conversion
It might be helpful to add a wavelet transform to the Fourier transform, as it seems to me that, with its help, we could see temporary and transient events in greater detail. It could also be possible to see the phase changes of overtones in a signal more clearly, and to recognize tremors or changes in sound pitch more accurately. It would be a very interesting opportunity to have. No other analyzers currently do this.
There is a wavelet transform plugin in the QM Vamp Plugins set (and therefore in the Vamp Plugin Pack).
I'm not sure how useful it is. Probably not very, as it stands, because I can't recall ever hearing of anyone using it. I know very little about wavelets and can't really judge, but I would be curious to know what a more useful plugin might look like.
