I'm thinking about a (fat) union API.

Well, it depends on how big is the difference... this is a reason why
I'm asking you if you think this is possible... after all I know just
about VST, LADSPA 1.1 and LV2, and they don't seem to be that much
different (I mean at a logical level).

Good point! This is true, but there are lots of sound processing
plugins around, so maybe instead of creating a new API and then apply
some "compatibility layer", it should be better to create a wrapping
tool natively. I think it should be also easier to expand.

True, but I was thinking about a more "sophisticated" idea of
For example you might want to write a library to implement sound
processing with already-instructed neural networks, and you wish to
load values from a text file (which would actually be your "processing
With this ideal architecture you don't have to create a new engine
from scratch and wait for other programmers to implement it. You would
just write a module, and that would work with any program using this
I know my English isn't perfect, I do what I can. :-)
P.S.: I think I've also found a name for it: "Naspro", an recursive
acronym meaning "Naspro Architecture for Sound PRocessing Objects".
The "Naspro" is a southern italian type of icing used for sweets.
