Clownfish Voice Changer review

Clownfish is the simplest free choice. It installs on your capture device at system level, so every app that uses the microphone, including Steam, Discord, TeamSpeak and Mumble, hears the changed voice without picking a virtual mic. The built-in list is short: alien, Atari, clone, mutation, male, female, helium and baby pitch, radio, robot and custom pitch. VST plugin support lets you add your own effects, and a sound player fires clips from hotkeys. Since version 1.90 Clownfish can route audio through VC Client, open source software for AI voice conversion, though setting that up means downloading models and running a separate local server. The main app runs on Windows 10 and 11, with a Chrome extension and a console edition for other systems. It is free under a permissive license, but the effects sound basic next to AI tools, and installing or removing it needs admin rights.
