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, dp _______________________________________________ Linux-audio-user mailing list Linux-audio-user@xxxxxxxxxxxxxxxxxxxx http://lists.linuxaudio.org/mailman/listinfo/linux-audio-user
