So, I played a bit with software synthesizers in the past and last week I took the project up for revision. Doing so, I came up with the following easy waveform generators:
Sine: double wave_sine(double x) { return sin(x); }
Square: double wave_square(double x) { return (abs(x)-floor(abs(x)))<0.5?-1.0:1.0; }
Saw tooth: double wave_saw(double x) { return (abs(x)-floor(abs(x))); }
Triangle:...
