See PDF at https://raw.githubusercontent.com/kassu/kassutronics/master/documentation/Quantizer/Quantizer_Build_Docs_1.1A.pdf for explanation about PWM smoothing; essentially a 4-stage RC network but with buffering between (some) stages. Needs a TLC7524/AD7524 (a simple DAC that's still sorta analog) and a switch of some sort to the recipient; and (b) describe the limitations and the MCP4922 DAC (others may work). Probably can build our own based on the front panel. - Current.
