LoFi effects pedals could be fun.
- lb1lf 6y ago-The 12 bit A/D provides a (theoretical) 72dB of S/N, so if you can do that at a decent sample rate to get sufficient bandwidth, the digitizing should be good. As long as the PWM D/A has a good clock to keep the PWM ratio accurate, I think it should be eminently listenable, given a proper reconstruction filter and a decent power supply. It would be fun to try this.
