sudo pip install pyvoicechanger



  • Python 3.6+
  • PyQt 5.10+
  • Sox (Linux package).
  • Working Microphone, Speakers and Sound System.
  • Working Sound Loopback Kernel Module


If its not working

modprobe snd-aloop

This command MUST be successful, Sound Loopback Kernel Module MUST be up & running, if it fails you dont have Sound Loopback Kernel Module up & running, if it says modprobe: FATAL: Module aloop not found ... it failed, please check your Distro Documentation about Sound Loopback Kernel Module to fix it, sometimes you need to enable it, or recompile it, or reinstall it, or whatever (that is not my Bug, complain to your Distro).

Check your Python version executing python --version, it should say 3.6.0 or higher.

You can’t perform that action at this time.
