I wanted to give you an idea of what using wavelets is like. This is just scratching the surface, but it’s stuff I happened to already know how to do. Basically, you can transform some data, mess with it, and transform it back. What you get out of it is useful manipulations localized in both time and frequency. That’s the wavelet’s major advantage over something like a Fourier transform… all that localization means that they deal with nonstationary signals quite well.

Enjoy!

[EDIT: If you download the FREE Mathematica Player, then you can play with the demonstration code I made on as many random walks as you like. Just download the demo file 20090925WaveletDemo.zip. The mathematica player also gives you access to thousands of cool demos at the Wolfram Demonstrations Project.]
