No idea, all I know is that most of the audio DSP systems I know of use
fixedpoint DSPs. Possibly due to cost contraints.

Not really, most audio DSP chips use fixedpoint maths, which you cant
use in C very well, and LADSPA plugins are 99% floating point.
Can you explain why you feel you can't use FixedP in C very well? Sure -
that's a fair comment and a design decision once some project
like this gets started. I just brainstorming. However, even with an
onboard DSP, which is most likely what Pro Tools does, we'd still need
to map from LADSPA C code to DSP code. Is that easy?
I would think it's easier than mapping gates.
I have not ever looked at LADSPA code. I assume most people write in C.
Today's DSPs, even 10 years ago, have a full compliment of C programming
tools. Bingo.
Yes, but coding
for DSPs is really hard work, and LADSPA plugins wont
port over as they use floating point maths.
I don't understand what you mean here either.
As far as DSPs that have FltP: The 320 has FP, the 2106 has FltP, etc
Do you mean they're too expensive?
