i am using wavelet transform (cwt) on a sound signal. I want to extract a particular frequency component (envelope) from it. i am able to get the scalogram, but how to get amp-time graph of a particular frequency? i can use filters (or H-xform), but dont want to. (in my project, i need both time and freq related info.)
My aim is feature extraction for an ANN in the next stage.
