Dev board (in some cases) Arduino + DAC https://www.youtube.com/watch?v=t3kUPjdiq0o for explainer https://drive.google.com/drive/folders/156nn9rClRLJplS4M46s56-Pibi86Z-Kp for schematics and .ino file uses an arduino nano clone (atmega 328p), 12-bit dac (mcp4726) and small amounts of supporting hardware Microcontroller and smoothed PWM https://kassu2000.blogspot.com/2019/10/quantizer.html using a gate.
