True!
I only worry about the garbage collector. Audio processing is
my biggest
fear case when there is a GC involved that is known to execute
unpredictably, often taking a very long time in the rare event
it does execute.
On OS-X there are at least two ways to do audio programming. The
easiest is to use a large buffer and use a pre made AudioUnit.
The low latency option is to write your own AudioUnit which is
called as a callback by the kernel on a real time thread (20+
times per second) and communicate with this thread from the main
program using CAS instructions to avoid race-conditions. I guess
it doesn't matter too much if the main program is under GC if the
called from the AudioUnit never is touched by GC and all objects
transferred to the AudioUnit is not under GC.
Might be possible, depending on how GC works on OS-X with D.
