Then you're not talking about real-time ("streaming")
processing. You're talking about processing, say, a static file to
pitch shift it. LADSPA can support this, but as you note, there's no
way for the host to ask the plugin "are you done yet?", so its hard
(but not impossible) to do correctly.
VST offers this, though its normally not implemented correctly :)
