Exactly. It is mainly a framework with a couple of small demo-apps. Not 
released yet but some graph types already work quite well, even if 
totally unoptimized in the display code.
To handle thousands of samples some optimizations would be needed, also 
probably a new graph type

I remember to have seen a sophisticated application about audio stuff at 
FOSDEM in the GNUstep room, it was running on mac and I don't know if it 
was opensource or not and ever ported to GNUstep...
