What about a Fast Fourier Transform? Couldn't you theoretically FFT the signal, implement a low-pass filter, and then inverse FFT it into a (relatively at least) very clean signal?

I'm thinking of fiddling around with this idea, as I have some code laying around that does FFTs very efficiently. I'm still a little concerned about the processing power involved, but if I get this working then I will go ahead and post it up somewhere online.

On the simpler side, though, the moving average is nearly unbeatable. Our signals-processing mentor strongly encourages going after that idea before getting into steadily more complex ideas.
