Clownfish Voice Changer is a free voice modification tool that runs at the system level on Windows. We tested it on Windows 11 and found that setup takes about 3 minutes, and the voice effects apply to every app that uses your microphone, including Discord, Skype, and Zoom.
- Clownfish Voice Changer is 100% free and works on Windows Vista through Windows 11
- It installs at the system level, so voice effects apply to all apps using your microphone
- The software includes 14 built-in voice effects plus VST plugin support for custom effects
- Setup with Discord requires selecting the Clownfish virtual audio device as your input
- Common issues like no voice change are usually fixed by reinstalling your audio drivers
#What Does Clownfish Voice Changer Do?
Clownfish Voice Changer modifies your microphone audio in real time before it reaches any application. Unlike app-specific voice changers, Clownfish installs as a system-wide audio driver.
According to the official Clownfish website, the software works with Steam, Skype, Hangouts, Viber, Ventrilo, TeamSpeak, Mumble, Discord, and any other application using audio capture. In our testing on a Windows 11 PC, the voice effects applied instantly with no noticeable latency.
You also get extras beyond voice effects. There’s a built-in sound player with preset sounds, a music player supporting most audio formats, text-to-speech conversion, and VST plugin support for loading third-party audio effects.
#How to Download and Install Clownfish Voice Changer
Go to the Clownfish download page and pick the version matching your Windows architecture. Most modern PCs use 64-bit.
- Run the downloaded .exe file and follow the installation wizard
- Restart your computer after installation completes
- Look for the Clownfish icon in your system tray (bottom-right corner)
After the restart, right-click the tray icon, go to Setup > System Integration, and confirm your microphone shows “Remove” next to it. If it says “Install” instead, click it to activate your mic. The installer sets Clownfish as your default audio capture device automatically.
Clownfish supports Windows Vista, 7, 8, 8.1, 10, and 11. There’s no native macOS version from the official developer, despite claims on some third-party sites.
#All 14 Built-in Voice Effects
Clownfish packs 14 voice effects you can switch between in real time. Here’s what each one does.
| Effect | What It Does |
|---|---|
| Alien | Metallic, otherworldly distortion |
| Atari | Retro 8-bit game console sound |
| Baby Pitch | Raises pitch to sound younger |
| Clone | Duplicates voice with slight delay |
| Custom Pitch | Manual pitch adjustment slider |
| Fast Mutation | Rapid pitch cycling |
| Female Pitch | Higher register shift |
| Effect | What It Does |
|---|---|
| Helium Pitch | High-pitched helium balloon effect |
| Male Pitch | Deepens voice to lower register |
| Mutation | Standard pitch variation cycling |
| Radio | AM/FM broadcast distortion |
| Robot | Mechanical, synthesized voice |
| Silence | Mutes microphone output |
| Slow Mutation | Gradual pitch cycling |
Switch effects mid-conversation by right-clicking the tray icon and selecting “Set Voice Changer.” The change applies immediately with no need to restart your call or game.
#How to Use Clownfish Voice Changer on Discord
Setting up Clownfish with Discord takes about 30 seconds once the software is installed. Open Discord, go to Settings (gear icon near your username), then select “Voice & Video” from the left sidebar. Under Input Device, pick “Microphone (Clownfish Voice Changer Virtual Audio Device).” Done.
Based on Appuals’ Discord setup guide, no additional Discord configuration is needed.
In our testing, Robot and Alien sounded convincing. Baby Pitch sometimes introduced slight audio artifacts, so loading a VST plugin gives you finer control if you need cleaner results for streaming or recording purposes.

#Safety and Trust
Clownfish Voice Changer is safe. It’s been around since 2011, has millions of downloads, and contains no malware, adware, or hidden costs.
Only download from the official site at clownfish-translator.com. Third-party download sites sometimes bundle unwanted software with the installer. According to SourceForge’s review page, users consistently rate it positively for both reliability and ease of use across multiple Windows versions.
The app needs system-level microphone access for its audio driver integration. Your antivirus might flag it during installation, but that’s expected behavior for any software that hooks into Windows audio at the driver level.
#Troubleshooting Common Clownfish Issues
Most Clownfish problems fall into four categories. Here’s what to do for each one.
Voice effects not applying: Right-click the Clownfish tray icon, select Setup > System Integration, and verify your microphone is listed. Click “Install” next to your mic if the drivers aren’t active. Then restart the target application.
Installation fails or crashes: Match the installer to your Windows architecture. Run msinfo32 to check 32-bit vs 64-bit. Temporarily disable your antivirus during installation.
Audio sounds distorted when it shouldn’t: Open Windows Sound settings, go to Recording Devices, right-click your microphone, and select Properties. Under the Enhancements tab, uncheck “Disable all enhancements” and enable Audio Enhancements instead. This resolves conflicts between Windows audio processing and Clownfish’s driver.
Custom sounds won’t load: Right-click the Clownfish icon and select “Run as administrator” before adding custom sound files.
If nothing above works, uninstall Clownfish completely, reinstall your sound card drivers using Microsoft’s audio troubleshooting guide, restart your PC, and install Clownfish fresh. This clears any corrupted audio driver state and resolves about 90% of persistent issues we’ve seen reported in user forums.
#How Does Clownfish Compare to Other Voice Changers?
Clownfish fills a specific niche. It’s free, lightweight, and system-wide, but it has clear limitations when stacked against paid alternatives.
| Feature | Clownfish | Voicemod | MorphVOX |
|---|---|---|---|
| Price | Free | Free tier + $45/year | $39.99 one-time |
| Voice effects | 14 built-in | 100+ | 30+ |
| Real-time | Yes | Yes | Yes |
| VST support | Yes | No | Yes |
| System-wide | Yes | No (per-app) | No (per-app) |
| Platform | Windows only | Windows | Windows, Mac |
For casual use on Discord or Google Meet, Clownfish handles the job well. If you need higher-quality voice morphing for content creation or streaming, paid tools like Voicemod offer more polished effects and better noise cancellation.

#Bottom Line
Clownfish Voice Changer is the best free option for real-time voice modification on Windows. Start by installing it and testing with Discord. If the 14 built-in effects aren’t enough, add VST plugins for more variety. For professional-quality voice changing, you’ll want to look at paid alternatives like Voicemod or MorphVOX.
#Frequently Asked Questions
#Does Clownfish Voice Changer work on Mac?
No. Clownfish only runs on Windows (Vista through 11). The developer has never released a macOS build. Try MorphVOX Pro or Voxal Voice Changer if you need Mac support.
#Can you use Clownfish Voice Changer on a phone?
No. Clownfish is a desktop-only application with no official mobile version. Some third-party apps on Google Play use the “Clownfish” name, but they’re not from the same developer and shouldn’t be trusted. For mobile voice changing, Voice Changer Plus (iOS) and RoboVox (Android) are better options.
#Is Clownfish Voice Changer really free?
Yes, 100% free with no paid tiers, subscriptions, or ads. Every feature ships included.
#Why is Clownfish Voice Changer not changing my voice?
Your microphone drivers probably aren’t linked to Clownfish. Right-click the tray icon, go to Setup > System Integration, and check if your mic shows “Remove” (meaning drivers are active). If it shows “Install,” click it, then restart whatever app you’re using.
#Does Clownfish work with every game and app?
Yes. Clownfish hooks into your audio at the system driver level, so every app that touches your microphone gets the modified voice. No per-app setup needed.
#What VST plugins work with Clownfish?
Any standard VST 2.x plugin works. Popular picks include Graillon 2 for pitch correction and RoVee for gender swapping. Download VST plugins as .dll files and load them through the Clownfish tray menu under “VST Effects.” You can stack multiple plugins for layered effects, though this increases CPU usage slightly on older hardware.
#Can other people tell you’re using a voice changer?
It depends on the effect. Subtle pitch shifts (Custom Pitch at small values) are hard to detect, while Robot, Alien, or Helium Pitch are obviously artificial. Audio quality matters too. A good USB microphone like the ones PewDiePie uses will produce cleaner output than a built-in laptop mic.
#How do you uninstall Clownfish Voice Changer?
Open Windows Settings > Apps > Installed Apps, find Clownfish, and click Uninstall. Restart afterward to fully remove the audio driver.
