Cesare, David:
Thanks for the recommendation. I figured Rubberband would be the ticket,
but it's always good to ask. :)
However, it would be nicer if RB had a simple option to alter by direct
tempo value instead of percentage change, i.e.:
rubberband --intempo 120 --outtempo 115 foo-120.wav foo-115.wav
That would eliminate a calculation on the user's part and simplify the
process.
Best,
