Analog Output Without a DAC?

The ESP32-S3 doesn't have a DAC - that's no problem for us! Thanks to PCBWay https://www.PCBWay.com/?from=atomic for sponsoring the channel.

I've been using I2S to output PCM data to an amplifier - but recently I've been using a board that only has a buzzer. Can we get audio to come out of it? Of course we can!

Sample code is here: https://github.com/atomic14/esp32-pdm-audio
