What is your goal in processing? I used to do a lot of image processing with wavelets, so curious on how much is applicable knowledge here. In images, edge/feature detection and smoothing are some of the main goals.

For starters, this can be an efficient way to set up voice activation. Sound signals are generally temporally compact, and somewhat sparse in Mexican hat basis.
