Ok, we must be talking about different things... Let's say
I have a simple host that reads a 8bit mono file, processes
it with a LADSPA plugin and writes to another file. If
my host doesn't recognize formats used by the LADSPA plugins,
how can it fill the plugin buffer? Or are plugins supposed
to support 8bit data? Converters? What am I missing?

And don't say use converters. Converting data is expensive. In my own
apps, I've tried to limit converting to two specific places: 1) when
data enters the system, 2) when it's outputted. I don't want to
start doing conversion before and after every plugin.

Oh yes, we convert it to 26 *mono* streams. That's just what I've been
suggesting. But no brains here so I'm just guessing... >;)
