## plugs
### crap_eq
multiband parametric EQ. try redefining BANDS.
### crap_eq_const
simplified code for a response defined at compile-time.
simplified code for a static response.
one day, this will be faster with compile-time constants.
### crap_noise
white noise generator. loud, full-range, 0dBFS. don't say i didn't warn you.
## build notes
`make` it. optional `bench` benchmarking target, doesn't build on Windows.
if you're using gcc, try `CFLAGS='-O3 -ffast-math'`.
`-march=native` actually seems to degrade performance slightly, but YMMV.
if you're using clang, (at the time of writing this)
you can't tune performance that much so just use `CFLAGS='-O2'`.
can be cross-compiled for Windows for use in Audacity or a LADSPA wrapper.
