Can ESP32 receive analog studio microphone input?

Postby clarkc5 » Sun Dec 12, 2021 12:38 am

Hello, I want to make a device that can receive input from a high quality microphone (TRS cable). Can ESP32 do this?

Here is an example of a microphone I would like to use

More specifically, it can do this (and retain the high quality) when combined with an appropriate I2S codec.

It can with a corresponding ADC as the built in ADC isn't good enough for audio but if you look at Espressif audio boards the ES7210 4 channel ADC is an option they use
