This is a really long winded and long standing offtopic gripe I have with
general application development under Linux. The only way I'm going to
get folks to understand my position on it is if I code it up in my
implementation language of choice with my own APIs.
There's a TON more that can be done with QoS in the kernel (EDL schedulers),
DSP JIT compiler techniques and other kernel things that can support
pro-audio. I simply can't get to yet until the RT patch has a few more
goodies and I'm permitted to do this as my next project.
I had a crazy prototype of some DSP graph system (in C++) I wrote years
ago for 3D audio where I'm drawing my knowledge from and it's getting
time to resurrect it again if I'm going to provide a proof of concept
to push an edge.
Also, think, people working with the RT patch are also ignoring frame
accurate video and many others things that just haven't been done yet
since the patch is so new and there hasn't been more interest from
folks yet regarding it. I suspect that it's because that folks don't
know about it yet.
