"""
list_devices.py
===============
Utility: list every audio device sounddevice can see, with its index, so you
can fill in INPUT_DEVICE / OUTPUT_DEVICE in your .env or config.py.

Run:
    python list_devices.py

Look for:
  * your microphone in the INPUT column, and
  * "CABLE Input (VB-Audio Virtual Cable)" in the OUTPUT column
    (that is the device this tool should send translated audio to).
