I have a question about beatsin* family of functions.
The very last parameter is “phase_offset” (default value is 0).
What is format here, what units?
I would like to generate two sins the same beat rate but opposite phases, phase shift is 180 degrees, what should I use as phase_offset?
sin1 = beatsin16(60, 0, 255, 0, 0); //first sin
sin2 = beatsin16(60, 0, 255, 0, 0/?/); //second sin
