From what I quickly read it "sums" the left and right channel to give you a higher frequency. From what I remember of science class somehow it would have to "time shift" one channel to give it the ability to overlap the two "waves" so that it doubles the frequency to 38k. Can someone that knows tell me if my theory is right?
That's right. The phase shift should be exactly 180 degrees to sum the frequencies properly. Also LEDs threshold plays significant role here (check out how charlieplexing works), you need to generate the signal so it turns the LEDs in precise intervals. There are a lot of small things about it and I spent plenty of time perfecting the parameters of the code.
And Ernie lighten up on the man a little, he's tinkering. Don't we all like to tinker? :)
Thanks for support! :)
