# esp32-rx
|
|
|
|
This is a sample project for receiving audio data using [ESP32](https://www.espressif.com/en/products/socs/esp32) microcontroller.
|
|
The chip has a built-in 12-bit ADC which is used to process the analog audio from the external microphone module in real-time.
|
|
The program also support input from I2S MEMS microphones that does not require the usage of the ADC.
|
|
The received messages are optionally displayed on the attached OLED display.
|
|
|
|
