<b>Subject:</b> [sdiy] Quantizer DAC or PWM?</font>
<div> </div>
</div>
<div class="BodyFragment"><font size="2"><span style="font-size:11pt">
<div class="PlainText">I’m working on developing a quantizer module for eurorack. 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>
