I'm completely new to audio processing, but here's an idea I would like at least a "yay" or "nay" on technical feasibility...
Might it be possible to take nearly any track of rock music and do the following with software:
- separate the vocals (using the typical lame methods -- emphasizing the center-positioned audio, etc)
- send the vocals through a filter that removes tonality and another one that introduces some rough-grain distortion
- mix these altered vocals back into the track and viola! you have a screamo version for the sake of silly gags
