Installing Clownfish Voice Changer should be an easy task. Just keep pressing Next button :-)

Main menu

When you start the application Voice Changer logo icon will appear in Windows traybar. When you right click on this icon main control menu will appear. Double-clicking on icon turns on and off the application. When Hear microphone option is checked you will be able to hear your modified voice. From VST Effects menu you can manage and configure your VST plugins .

Select effect dialog

Main Voice Changer Window - here you select active voice effect. When enabled the icon gets colored. If you want to stop all effect press Clear effect button. This window is opened from Set Voice Changer option in main menu.

Music playlist dialog

Music Playlist Window - here you can mange and control your background microphone's music. Supported commands - play, stop, pause, resume, next/prev track, volume control.
Adding music source from Internet (YouTube, Vimeo, etc.) is possible by installing - required filter.

Setup dialog

To use Clownfish as voice changer you have to install it on the capture device you want to modify. By default Clownfish is installed on default audio capture device. If you want to install it on other devices you can do this here. Installing/Removing Clownfish requires Administrative rights. This window is opened from Setup option in main menu.

Setup dialog

Voice Assistant - helper tool that converts text into speech. You can select different voices from drop down menu.

Setup dialog

Sound Player - here you can play various sounds. When hotkey is pressed - a predefined sound will be played.


Q: Why the application does not install on my machine?
A: Make sure you've downloaded correct installation package. 64bit version wont install on 32bit OS and vice versa. Note that you will need administrative rights to make installations.

Q: Application installs correct but the voice is not changed. What can I do?
A: Go to audio settings, recording devices. Right click on microphone ->Properties. If the dialog has an "Enhancements" tab, go to that tab. Make sure the "Disable all enhancements" check box is unchecked, even if you don't use any of the enhancements in the list. If the dialog does not have an "Enhancements" tab, go to the "Advanced" tab. Make sure the "Enable audio enhancements" check box is checked.
There are four different installation modes ( Clownfish's Setup menu ) - try each of them and check if this will help you ( remove device, change mode and install device)

Q: In some cases I cannot add custom sounds. Help?
A: Try running Clownfish as Administrator. The other option is to add them manually ( paste sound files in C:\Program Files (x86)\ClownfishVoiceChanger\sounds ) and restart CF.

Q: How can I restore my sound card settings?
A: In general if you uninstall Clownfish the old behaviour should be restored. However if something goes wrong you can reinstall your audio driver software.

Q: Clownfish dialog is transparent. Icons are not accessible. What's wrong?
A: If you experience problems with user interface you can force the application to work in non-colored mode. You have to edit Clownfish's shortcut and add startup parameter -nocolor in Target textbox.


Clownfish: Clownfish and anemonefish are fish from the subfamily Amphiprioninae in the family Pomacentridae. About twenty eight species are recognized, one in the genus Premnas, while the remaining are in the genus Amphiprion. In the wild they all form symbiotic relationships with sea anemones. Depending on exact species, clownfish are overall yellow, orange, reddish, or blackish, and many show white bars or patches. The largest species reach a length of 18 cm (7 in), while the smallest barely reach 10 cm (4 in).
