Realtime optimized encoding/decoding kernels

[mtmccrea]

The current encoding and decoding kernels are linear phase, meaning they sound great ;), but as such there is a delay in the signal, which may not be ideal in some live situations. This issue is to make note of the discussion we've had about minimum phase or "mixed phase" filters which would minimize the delay. This implies a good amount of research and experimentation!

Just getting the thread going...
