Clownfish Voice Changer review
A free desktop voice changer with system-wide effects, plugins, and hotkey sound playback.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Clownfish Voice Changer modifies microphone audio for applications that use an audio capture device. It is aimed at desktop users who want live voice effects without a paid plan: the software is free and MIT-licensed. Presets include alien, robot, radio, helium, and baby voices, alongside pitch changes and custom pitch control. The product is a fit for people who want to alter a live microphone feed or add sound playback to communication sessions, rather than users looking for a dedicated recorded-audio editing workflow.
Its feature set extends beyond presets. Clownfish includes a music player with playlist and media-format support, a built-in sound player with hotkey playback, text-to-speech assistance, profiles, and audio-device selection. VST and VST3 plugin support gives it an additional path for audio effects. The system-wide approach and integrations with Steam, Skype, Discord, TeamSpeak, Mumble, Ventrilo, Jitsi, Viber, and Hangouts make it relevant to users moving between communication applications. External VC Client AI voice-conversion support is also listed, though it is an external option rather than one of the built-in preset effects.
Platform choice deserves attention. The primary application is presented for Windows; macOS and Linux are listed for separate Terminal Editions, while Chrome/Chromebook is offered as a web-store option. That makes Clownfish most suitable for Windows users who want free, configurable live effects and sound playback, and for technically comfortable users willing to choose the edition that matches their platform. People seeking a single consistent desktop application across operating systems, or tools centered on transforming recorded audio, should consider alternatives.
