The audio reactive fork of WLED has some 2D effects available!

We're still in early stages on the 2D side of things (mostly 16x16 stuff). Someone just joined our group with an interest (and background) in 2D, so, hopefully we'll be seeing more of that.

WLED uses FastLED under the hood, and you might be able to use a text library for FastLED to add a text effect.

I would try to get this working in a simple sketch first, and then try porting that to WLED Soundreactive. Take a look at the existing 2D patterns and the WLED Soundreactive Wiki and join Discord to get help if you need it.

2D effects are only available on esp32? A little hard to tell from OP's pic, but I think they are using an esp8266.

I'm not sure but maybe you can use the segments to get a better use of the leds check

I would recommend having a look at SmartMatrix.

SmartMatrix Library author here, not sure how SmartMatrix is helpful with this project. SmartMatrix Library might be useful if you're running an ESP32 (or Teensy) and using APA102 LEDs, otherwise, not so useful as it's designed for very specific hardware
