https://stream.echo6.co/videos/watch/779ab503-35fa-4320-bd58-fa763818d28b A well-kept secret of the ESP32 is its extended audio capabilities because it is hard to use. Luckily, I found a library and a toolset enabling us to easily use these capabilities. We can now connect microphones, loudspeakers, Bluetooth loudspeakers, SD cards, and even browsers to an ESP32 to record and play sound. Very handy for all sorts of projects. And we will build an internet radio with a single line of code in the loop(). I am a proud Patreon of @GreatScott! , @Electronoobs , @EEVblog , and others.
