Hmm, we are not connecting plugins to each other. We are defining
a standard API for a callback function that modifies an area of memory.
The host calling this function must know the exact data format.
I think it's unrealistic to assume that the whole processing network
(inputs, processors, outputs) is based on LADSPA-plugins.

If we don't use a standard format, we'll end up in a situation where
there are LADPSA-plugins for ecasound (STL-vectors of sample data),
LADSPA plugins for Paul's latest Ardour version (26channel 24bit-in-32bit
data), LASDPA plugins for aRts/MCOP, etc etc ... Yep, sure we have a standard
plugin API, but most plugin-host combinations are incompatible.

And 32bit vs 64bit vs 128bit is not an issue. You can just compile for
multiple targets, without any changes in plugin or host code.
