This would be a request for https://github.com/Aircoookie/WLED-WebInstaller. In fact you can make a custom build for -C3 with audioreactive usermod, so its supported as much as possible already.

On the other side - honestly - you will not get happy with audioreactive on -C3. The -C3 chip is so slow that it cannot run our audio analysis in realtime any more. Audioreactive will use 100% CPU, and still lag behind noticeably. As a side-effect, your WLED animations will become slow, too. For -C3, my recommendation is to only use audioreactive as "sound sync receiver" client for a more capable MCU that does audio processing.

About the webInstaller: it was decided to only provide one pre-build firmware with audioreactive at this time (for "classic" esp32), because audioreactive is "just" one usermod. This may change in the future, as -S3 (and -S2, if you accept some limitations) are also able to run audioreactive.

I'm closing this report, as there is nothing planned on WLED source code side to improve audioreactive performance on -C3. Again, the -C3 chip is very slow compared to other esp32 variants, this is a limit that's very hard to "trick out".

Please feel free to make a request in https://github.com/Aircoookie/WLED-WebInstaller.

Thanks for response @softhack007. Do you know variants of ESP32 will run ok with audio reactive?

Maybe the page https://kno.wled.ge/advanced/audio-reactive/ should be modify to include the recommended models and a warning for other models.
