<div>Preliminary tests seem to imply this works really well actually. I'm pleasantly surprised, I was able to put some pointless number crunching in the non-audio thread and spit to the screen, sending my python process up to 30-40% Cpu use and gnome -terminal up to about 50% ( on a quad core chip mind you ) without noticing any underruns. Mind you, I have no idea what the real latency is, I have my buffer set at 64, but dac.getStreamLatency() is reporting 0.00 so I might have to benchmark.<br>
</div><div><br></div><div>Wondering if either of you would happen to have an idea of how I could easily make the audio gen really audio heavy? </div><div><br></div><div>An ideal benchmark I think would be to get some audio-in, process it, and spit it out, but that may take a while.</div>
<div><br></div><div>The gen as is now:</div><div><br></div><div>0.5 * cos( 2. * 3.1416 * self.freq * self.idx / SAMPLE_RATE )</div><div><br></div><div>perhaps making a matrix of a whole bunch of those would do it.</div><div>

Hi Iain,<br>
<br>
If it helps, there is a python wrapper for RtAudio in the latest release of RtAudio (look in the "contrib/python/" directory).<br>

> Hi, I'm working on an a project that I intend to do using the STK, 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 I want to have a python master callable that gets called once per audio sample and has a way of sending out it's results.<br>
