3,5 aux line in

Hi. I am doing lights for a club using ws2812b and wled. Now I have a INMP441 mic and it works fine but when the music is quiet and the audience cheers it of course picks up the ambiance noise.
Is it possible to get the signal from the mixer instead and plug in a 3,5 line in into my esp32 somehow?

The digital mic option just uses i2s, so if you find a little i2s ADC module it should work and not even see the difference.
