Hi List,
Here's a tiny experimental tool I've been working on the last couple
of months:
http://zwizwa.be/rai/rai.html
It's mostly aimed at the music DSP world (sound synthesizers and
effects) where feedback structures are very important, but it could
be fairly generic in its use. I tried to stay as close to Scheme as
possible.
The basic idea is to use Racket as replacement for Matlab, i.e. to
analyze algorithms specified in a high level format, and use it to
generate dependency-free C or ASM code for deeply embedded targets.
Currently it can generate binary plugins for Windows VSTi, Pure Data
and Jack Audio.
This looks totally awesome. Would you consider making a Racket
Package out of this? My fall class could definitely be interested.
Cool :)
Here's the package:
raco pkg install github://github.com/zwizwa/rai/master
That will run all the Racket code.
For the C code gen, the Makefile is the best point of entry.
Currently Linux only, and might need some tweaking.
added synth-lib.rkt basic synth kit and synth.rkt example synthesizer.
- envelopes
- parameter control dezippers
- parameter control scales (exponential, "squashed" exponential, ...)
- SVF filter
- supersaw osc
- anti-aliased saw osc
- saturation functions
- FDN reverb tail
How I use it at this time, Linux + Pd:
make sp_host.pd_linux # build binary Pd wrapper
pd sp_test.pd & # run Pd patch built around sp_host
make livecode # continuously compile synth.rkt -> synth.sp binary module
then edit synth.rkt or any of its dependencies and the binary code
running in Pd will be updated, leaving state intact if the type didn't
change.
