The "expand" feature in snd does real-time tempo change to audio
without affecting pitch. I *think* that snd is GPL, and if so,
then maybe some code could be ported from there. Yes, it's a
hard problem, but there might be a headstart available.

Sorry about being vague. I'm after a global speed control in a
window that can remain open, rather than requiring an "ok" click
to accept the tempo change, and avoids a window closing side
The global speed slider idea sounds great. The slider wouldn't
have to be in the top-level window tho.
It would be OK with me if the slider was disabled the moment
that someone pasted audio into their song. Changing audio tempo
too would be truly awesome -- I bet someone would probably write
an article about that feature, either in LJ or on /. That could
get some notice outside the Linux world too, not that it's not
already done outside Linux, just that it removes one more hurdle
in moving to Linux audio.
