In the case of audio boards—development boards made specifically for audio processing—they typically include dedicated hardware for handling audio signals more efficiently form the start, rather than requiring you to add components later. These boards often feature analog-to-digital (AD) and digital...

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 https://www.bhphotovideo.com/c/product/ ... KX0EuS-oVY Thank you...
It's probably still useful, but I would recomment people check out the fantastic work here:https://github.com/pschatzmann/arduino-audio-tools ESP32 I2S Audio Explanatory video of the analog mic boards here (MAX9814 and MAX4466)here
