How often are
more than one plugin with the same control inputs used in
paralel? I was rather thinking of colapsing (or swapping) plugins in
series. They'd have to be linear and time invariant, of course.
Or maybe plugins could 'know' how to colapse themselves, sort of like
overriding Plugin::operator+(const Plugin&), to use a C++ metaphor.
Well, stereo sounds passing through mono plugins is one case. However as Jeff describes this optimization, it is
applicable when
output signals are summed, and I don't know how often it happens.
Anyway it is another idea to optimize processing for linear plugins,
definitively not something to discard.
This makes me think that some common basic "pieces" like mixers and
delay filters can have special properties which involve even more
aggressive optimization. Maybe it's worth considering how this special
blocks could be developed and used.
you can think all you want. unless there a plugin->host callback that
allows the plugin to determine its operating environment in huge detail,
this kind of idea is pretty impossible to make use of.
