[sdiy] interesting digital circuits

[tuj at fuse.net]

Here's a question that doesn't seem to get a lot of attention: does anyone have any interesting digital circuit designs for processing audio?  I'm looking at using an 8-bit ADC that put all 8-bits out in parallel, and a corresponding 8-bit parallel input DAC.  I'd be very interested in hearing if anyone has any neat ideas that would fit into this scheme.
