So, I was trying to mess with noise cancellation on my arduino (I think I did it wrong now that I remember) but at the time I was wondering if it was feasible to generate a pseudo-sine (or triangle) wave (but mostly sine :D) by rapidly switching PWM duty cycle. I know a 16mhz AVR can do PWM at 8mhz(…

sine/triangle wave sound with PWM?
