I made a previous version using a PIC chip with a DAC which I abandoned during the chip shortage.<br>
Now I’m looking at taking up the project again but possibly with an esp32-s3 chip instead. This chip only has PWM, though.<br>
<br>
Question is whether PWM with smoothing circuit is it accurate enough for a quantizer? Does anyone have smoothing circuit to recommend?<br>
Or is a DAC the better option?<br>
