Hi, I'm working on an a project that I intend to
do using the STK in a
callback style, but am hoping I can prototype the architecture in python
... ... ...
until I've figured out the various components and their responsibilities and
dependencies. Does anyone know of any kind of python library ( or method? )
that would let me simulate the way callback based STK apps using RTAudio
work? IE
You could implement the callbacks (and link it to STK) with Cython.
(not CPython)
This would require you to write a Cython-Header file for the called
STK functions.
Cython works very well for this, although you have to learn it, because
it's neither real C nor real Python, but it's close.
With some attentiveness, you could write rt- functions in Cython,
because they compile to pure C / binary.
I want to have a python master callable that gets
called once per
audio sample
No, Once per audio buffer, consisting of many (e.g. 128) samples.
That's a better choice, usually, even if you do sample-by-sample
processing within the function/callback.
and has a way of sending out it's results to the
audio
subsystem.
I've found a bunch of python audio libs but it doesn't seem like they work
that way,
Note:
Don't use python threads (as implemented in CPython), they do not
work for this.
You might have more luck with the more recent multiprocessing module,
( http://docs.python.org/library/multiprocessing.html )
It was introduced to circumvent some of PythonThreads limitations.
