Most LV2 and LADSPA plugins do the DSP work in floating
point... so... yes. :-)

But, here's what I'm getting at. Suppose you optimize your
plugin chain for fixed-point (integer) math but use the
current LV2 protocol. A prosaic approach is:

1. Synth plugin.
generates audio.
Converts to float.
sends to next plugin

2. FIR filter.
Converts float to int.
Processes data.
Converts int to float.
Sends to next plugin.

3. Convolution Reverb
Converts float to int.
Processes data.
Converts int to float.
Sends to next plugin.

All those needless conversions don't settle right with me.

Why would we? Because they're mature technologies. Why
reinvent the wheel?

Maybe today, with tablets. But not their phones.
