[Stk] STK Problem

[Perry Cook]

Hey Chris,

You might want to check out the ragamatic project, which definitely
makes and puts out stereo.  It's in the projects directory.

I am currently working on a my student research project, a sonification of human movement, and I am trying to implement STK for this matter. I am not sure if I am addressing the correct persons for this problem, and, case I am wrong, I would be happy if you could direct me in the right direction.

Nevertheless, I am still troubling with a very basic issue: monophonic sound. I can succeed in sending only on sound sample to only on channel. I tried the sine function, which should sample a monophonic sound, but it doesn't. I get the sine on both speakers, left and right. I realized that the sine.tick(stkframes, channel) function should tick the samples only on one channel, but when I try this I either get a clean sine sound on both speakers or a modulated sine (it doesn't sound really well and I think what I am hearing IS in fact a modulated sine). I read through the class definitions, I even tried to change the functions of tick in the RtAudio/RtWvOut classes,but I am seriously stuck. My ultimate goal should be something like this:

I think I have to write the data interleaved, since it's the default stream parameter, so first comes left, then right, then left and so on. But I can't figure out the correct way. Any help you could offer would be much appreciated.
