hi shane,
i've done a python script to do some morphing using wavelet decomposition of
two sounds.
it was done for experimental pourposes and i liked its results very much.
you have to tweek the script a little bit to use your samples.

actually substititute s1 and s2 by your samples with
sf= A..sndfile("sound1.xxx")

and match their sizes with zeros or with wavelet coefficients already on
decomposition step.

note that it outputs different morphs of the two sounds. and that you can
remove the import pylab statement from the header as the script is not using
it. its here:
