Thanks for pointing me to Sonic Visualiser, Paul, it looks really
interesting.  I could get an A-B time map out of it, but not a mix or
any time-stretched audio: it does not seem to actually perform the
effect.  How do I proceed from here?  Do I find a time stretch plugin
which I can automate with the derivative of this time map, or..?
