Low bit depth does this.  Actually there used to be an audiosuite 
plug-in that could do this it was Chip Burwell's Power Transformer. 
I think you can do something like it with Cyanide too which is a 
little like PowerTransformer.  I really wish that Chip Burwell would 
come out of hiding and write a VST version of power transformer.  It 
was extremely simple and extremely cool.
