The input and output are infinite streams. I have a few questions:
1) Is it possible to change it to use arrows? How would it look like? 2) How would one implement an continuous time version?
For 2) I would like to implement something like that digital integrator, so I could create filters based on integrator loops like this one:
x(t) ----(+)----> Integrator --|---> y(t) ^ | |--------------------|
Note that x(t) would be a function, and I would expect to create a function y, based on this flow!
If you look for Arrows, Signal processing _and_ real-time efficiency, then you might be interested in my experiments with LLVM: http://www.youtube.com/watch?v=GNiAqBTVa6U http://arxiv.org/abs/1004.4796 http://code.haskell.org/synthesizer/llvm/ (you need some more repositories like http://code.haskell.org/~thielema/llvm-2.6/, http://code.haskell.org/synthesizer/alsa/ ... no fun of installation currently because I could not achieve to get some patches to llvm to hackage.)
