 ## Digital microphone
 
-The digital microphone is a [MP34DT05](https://www.st.com/resource/en/datasheet/mp34dt05-a.pdf), this chip, made by ST Microelectronics, is an ultra-compact, low-power, omnidirectional, digital MEMS microphone built with a capacitive sensing element and an IC interface; it produces an output coded in [PDM](https://en.wikipedia.org/wiki/Pulse-density_modulation). The PDM format is supported by our [PDM library](https://www.arduino.cc/en/Reference/PDM) that can be used also with our [ArduinoSound](https://www.arduino.cc/en/Reference/ArduinoSound) library which contains example sketches to use the sensor.
