Way to go, Matthew. We need more of this sort of work
published to demonstrate that Haskell is not only about
itself.:-)
I hope others would follow suit and show some of their
reaches kept hidden in their coffers. It is only by
exchanging ideas and by trial and error that a resonably
usable and consistent library of DSP could be built.
I was planning to try similar things you have mentioned
on your page, such as interfacing to "the fastest FFT in
the West" (FFTW) via GreenCard, and it pleases me to know that
you have decided to give Haskell a second chance as well.
(I am referring here to one of your previous posts.)
By the way, are you aware of Cilk - a multithreading
parallel programming model based on Ansi C (from the
same group that invented FFTW)?
I think that this, or other multithreading approaches,
should be seriously considered when attempting to interface
Haskell to C. Think about data presentation running
in a separate thread. After all the amount of input
or output data tend to be quite large in this sort
of applications. You might find it useful to see
my page http://www.numeric-quest.com/lang/nq_proxy.html
about using LinuxThreads with thread-unsafe library,
EZWGL.
