um, come on, you sit here and preach that I don't know what I'm 
talking about yet you can't even be right on the first sentence?

jitter is the standard deviation of the timings. Do you know what 
standard deviation is? It is the square root of the sum of the 
squares...

Now, if you are so intelligent as you think you are, you can see 
by simple dimensional analysis that you get the same unit as what 
you measured with.

While, this doesn't prove you don't have a clue about jitter, my 
guess is, you don't.

Believe me, jitter is a big deal. If you spent as much time doing 
music as you did programming, you'd realize that. Go spend 5 
years learning to play the drums properly then come back and 
we'll do some tests and see if you believe the same thing.


Also, if you simply removed the GC from D so it doesn't get 
called, then whats the point? Anyone can do that(more or less). 
If you used manual memory management, then whats the point? C++ 
already does that and does RT audio already. We know D can be 
made to do this already.

If you pause the GC so it doesn't get called a lot, then whats 
the point? If you run your software for 3 hours, if it going to 
survive or glitch?

Do you know what "design for the worse case scenario" means? 
While RT audio isn't life and death, it's treated that why by the 
professional community.

Just because it's acceptable to you to define RT audio in some 
way that justifies it for you does not mean it's RT audio. I'm 
not saying your software isn't RT, but if you use the GC in any 
way what so ever, you don't have RT audio... regardless if it 
behaves like RT 99.99% percent. (there is something about 
guaranteed *maximum* latency that you have to deal with)
