I present to you a Sound React Box. I modeled it to accommodate an ESP32 under WLED Sound Reactive and a MAX9814. I think other microphones can adapt to it.

There is a first hole for the cable passage to go to the LED strip which is a WS2812B. And a second hole for a USB-C socket.

List of equipment used:

• ESP32: https://www.amazon.fr/gp/product/B071P98VTG/ref=ppx_yo_dt_b_asin_title_o05_s00?ie=UTF8&psc=1
