i don't want you to be behind the window.
what I'm talking about is an API that (correctly) removes interaction
with h/w from the work done by 95%+ of all audio applications. It
provides an abstraction for dealing with audio that massively
simplifies the work of the application *and* allows for
inter-application data sharing and cooperation. this is provided for
in a way that supports real-time low latency systems as well as more
traditional applications. fundamentally, its based on what some people
call a "pull" model but i prefer to call a "callback" mode.
what i presented was the API used by clients. thats all.
so, i ask again, what's missing?
