Hi! I'm using a standard dyadic discrete wavelet transform to analyze acoustical signals. The calculation itself works, but I'm looking for a good way of displaying and quantifying the results. I have an array of transformation values w = [sn | dn | d(n-1) | d(n-2) | ... | d2 | d1 ] for each signal set I've analyzed. The toolkit I'm using (wavekit) supports bar graphs of the different scales on top of each other, and I've programmed a mesh plot that compares one scale across different data sets. These are both somewhat rough and do not make it easy to spot characteristics. I wanted to ask what other ways of visualizing wavelet data have been found advantageous. I do not yet know what I'm looking for specifically, which makes it a little harder. Frankly, I could also use tips to give a few graphs some extra shiny, as I'll have to present them at some point. Thank you! Andreas Steffen
