Audio source problem in WLED 0.14

1

Hi everyone, I’m using version 0.14 of WLED with audio reactive enabled. I have connected a MAX4466 microphone to the ESP32 device, wired to pin 26. I’ve enabled the audio reactive function and set pin 26 as the analog microphone. Unfortunately, it’s not working. I noticed that in the WLED audio source settings, it’s still showing digital. How can I change the input?

The MAX4466 is a very poor mic. If you want analog I would switch to a MAX9814

Also make sure you installed the firmware from a pc and not with OTA.

I made a few posts on this here: ESP32 + MAX9814 not possible

it doesn’t work, I connected the mic pin out to pin26 of the esp32-

I think you need to use an ADC1 input, not ADC2. So something like pin 36.

“On ESP32, only ADC1 pins will work for analog input while WiFi is active (pins 32-39). ADC2 pins will not work.”
