Can I use audio in as high resolution ADC inputs?

I've not used my Axoloti for a while, just returning to it.

Can I use the L audio input on the axoloti for high resolution ADC inputs? I'd like to get a decent precision measurement of a 0-3.3V value. I can scale that down with some resistors as needed.

Can I print that voltage to a serial over USB in Arduino console style?

nope, this will not work.

the Inputs are DC-coupled, that means, no DC voltage can pass.

Right idea, wrong words.

The inputs are capacitively (AC) coupled, blocking DC.
