@veronica LED strips (where you can control down to the level of individual LEDs, or as one big lump, or anywhere inbetween) all use one of a few popular standards. You solder/stick/clip them to one end USB-C to the other, with a magic box inbetween. This will run WLED, and HA will find it and it'll do what you want.
I'm in the UK, so use these locally made ones : https://lectronz.com/products/tiny-sound-reactive-led-strip-controller-usb-c
You do not have to use the microphone OC
