Go for an I2S MEMS microphone. Avoid analog microphones as they'll be very noisy and the ADCs on the ESP32 range are pretty rubbish.

You're pretty much limited to PDM microphones nowadays though there are some PCM ones still knocking around. PCM mics are considerably cheaper.

Audio is well supported on the ESP32 and there are plenty of libraries and sample code out there.

My last experiments have been with a logitech camera as mic, worked kinda well but unreliable. Seeing forward to the chips ive ordered
