    I'm not an expert on signal processing, but are you sure this is
    really a wavelet transformation? It looks more like a sort of time-
    frequency analysis (which does give a nice visualisation!), while
    wavelet transforms are supposed to be bijective. Can you reconstruct
    the original signal from the time-frequency distribution?

    Best wishes,
    Stefan
