Wavelet Transform Engine  
This Java applet serves as a wavelet transform engine. You can load your own signal by choosing one of the menus. The wavelet transform of the signal will be computed. Then you can save those coefficients in order to process them using whatever method you like. Finally you can load the processed coefficients into the applet to do the inverse transform.
