There are times I want to take a trance track and resample it to play twice as fast and at a much higher pitch. It's just fun.

However, I have to open a song's waveform in Cool Edit Pro or something and resample it there. Is there some non-media player software that can mess with audio (outside of changing it's playback speed) on the fly while I'm listening to it?

I've found a lot of code libraries for such a thing, but never any software. I wouldn't be posting if I could find it.

Check out Cockos REAPER. It's got a free, unlimited trial. You can do a lot more than resample with it, it's a full DAW; but it's got an easy "rate" slider for what you're talking about. You can use it for full mash-ups, and it's really nice. A license is only $60 for personal and small business use.

The guys developing it are real software enthusiasts too, and generally respond to feature requests.

Whoa, I like the way it looks. I would not use 99% of it given I already own CEP,
but I may look into it's finer features once I get done jamming to accelerated heavy metal.

Many thanks for passing that on!
