SoundSwitch

This script listens to two audio input devices and determins which one is louder at a given moment and presses programatically one of two defined keys. If for some time nobody is speaking or everyone at roughly the lame volume then it presses a third defined key.

With help of this you can for example switch between scenes in OBS to show the person who is currently speaking.

Installation

There are some python 3 dependencies which need to be installed:

pip install numpy sounddevice pyautogui

Usage

Run the script by just calling it:

./soundswitch.py

It will ask you which two devices you want it to listen to, on Linux it could look something like this:

➜ jeena@William soundswitch (master✗) ./soundswitch.py 
   0 HDA Intel PCH: ALC3271 Analog (hw:0,0), ALSA (2 in, 2 out)
   1 HDA Intel PCH: HDMI 0 (hw:0,3), ALSA (0 in, 2 out)
   2 HDA Intel PCH: HDMI 1 (hw:0,7), ALSA (0 in, 8 out)
   3 HDA Intel PCH: HDMI 2 (hw:0,8), ALSA (0 in, 8 out)
   4 HDA Intel PCH: HDMI 3 (hw:0,9), ALSA (0 in, 8 out)
   5 HDA Intel PCH: HDMI 4 (hw:0,10), ALSA (0 in, 8 out)

  18 upmix, ALSA (8 in, 8 out)
  19 vdownmix, ALSA (6 in, 6 out)
  20 VirtualCard0, ALSA (32 in, 32 out)
  21 dmix, ALSA (0 in, 2 out)
* 22 default, ALSA (32 in, 32 out)
Choose microphone 1: 6
Choose microphone 2: 22

In this case we chose the Webcam as the first device and the default device as the second device.

Note: The script can only press the buttons when OBS is the window with focus.
