I found this old (experimental) plugin and have updated it and enabled it for longer audio chunks than the original design. Give this a go (try the default settings first):
wavelet.ny (3.16 KB)
It is called “Wavelet…” (which is a reference to early experiments by Iannis Xenakis rather than to modern Wavelet theory).
Note that this plugin is only intended for experimental purposes - there is no error checking in the code, so if you do something stupid with it, it will do something stupid 
If you use it in your research and your research culminates in a published paper, please include a credit (and I’d be interested to read the final paper, if that could be arranged).
