+    The Microphone class handles all microphones compatible with sounddevice (and the underlying PortAudio library). Most microphones and sound cards are compatible, accross all OS (Linux, Mac, Windows).

+    ```python
+    from lerobot.common.robot_devices.microphones.configs import MicrophoneConfig
+
+    config = MicrophoneConfig(microphone_index=0, sampling_rate=16000, channels=[1], data_type="int16")
