Continous wavelet transform

Open tlecomte opened this issue 13 years ago • 2 comments

Continuous wavelet transform seems like an interesting alternative to STFT for time/frequency analysis.

See : http://www.phy.uct.ac.za/courses/python/examples/moreexamples.html#wavelet-analysis-continuous-wavelet-transform See also : http://kelvinchufei.blogspot.com/2008/01/wavelet-scalogram-using-complex-morlet.html

I'd like to see this, too. Continuous complex Morlet wavelet is basically the same thing as constant Q transform, which has a python implementation

Thanks for the links. It is indeed very interesting. Unfortunately I won't have any time soon to work on this... I would have loved to see this integrated in Friture (provided it is suitable for a realtime implementation).
