the test for many different frequencies, you can plot how your resampler
performs at different frequencies.

if you really wanted to.
And yes, I think unless you have a few years to spend only on coding
your project, I'd recommend working on some existing project, since
writing a modular synthesis app and sequencing and a good gui is a lot
of work.

But the unlikelyness of a priority inversion problem that has been
pointed out by others probably applies to any of the synchronization
primitives that came up in this thread, be it conditions, pipes or
semaphores.

this approach at what speed. Could it even outperform libsrc on both,
quality and performance, under some circumstances?

Measuring the same example with libsamplerate with SRC_SINC_FASTEST
gives a throughput of 1233140 samples/second, which means that my code
is about 41 times faster.

The only method for getting this right I've come up with so far is
trying to understand the timidity code...

Its a practical consequence of the "one size doesn't fit all" rule of
software development. But that way you can have interoperability while still
having diversity.

face with little overhead, so that you can provide
any abstraction the application will need on top of that, if its different
than what CSL provides.
The operating system (linux) currently provides these:
- a callback API (select/write)
- a blocking API (write)
- a non-blocking non-copyin
added JACK support to CSL, you could also mix the
output of all of these "sound servers" into JACK, without endangering your
latency properties.

The good thing about this is that applications (like ardour) would not even
