A free Discord voice changer for Windows, no card needed

What “free” actually means here

Plenty of voice changers say free and then hide the useful part behind a payment screen, a watermark or a trial that ends after three clicks. So here is exactly what you get with Mimicore at no cost, and where the paid plans start, so you can decide before you download anything.

The Free plan is permanent. It does not expire after a week. You get the 28 voice effects (robot, radio, cave, giant, ghost, chipmunk, demon and more), the soundboard with its built-in clips and your own, hotkeys, push-to-talk, noise suppression and a noise gate, plus the voice gallery of 19 ready-made original voices. On top of that, the Free plan includes unlimited live AI voice conversion with the gallery voices, and 60 minutes a day with your own cloned voice, which covers a long stream or several calls with friends. The effects, the soundboard and the gallery voices are not metered at all. Why is the free plan so generous? Mimicore runs on your PC, so it costs us almost nothing.

A new account also starts with 30 days of Studio access without entering a payment method, so you can try voice cloning and your own voices before deciding whether any of it is worth paying for. When that ends you simply drop back to Free. Nothing is charged unless you choose a plan yourself.

Why a voice changer for Discord needs a virtual microphone

Discord only listens to audio devices that Windows exposes as microphones. A voice changer therefore has to sit between your real microphone and Discord and present itself as a new microphone. That device is called a virtual microphone or virtual audio cable. Mimicore uses the free VB-CABLE driver for this and installs it for you from inside the app: open Live, go to Output, and press Set up virtual mic. The app downloads the driver from vb-audio.com, checks its signature and runs the installer. You click Yes on the Windows permission prompt, and restart if Windows asks.

After that, a device called CABLE Output (VB-Audio Virtual Cable) appears in Windows. In Discord you open User Settings, then Voice & Video, and pick that device as your Input Device. Discord now hears whatever Mimicore produces, and the same device works in Zoom, Teams, Google Meet and OBS, so you set it up once.

One setting trips up almost everyone: turn off Discord's own Noise Suppression and Echo Cancellation on that page. Those filters are built for natural voices and they fight a changed voice, which makes it sound thin or cut out. Mimicore has its own noise suppression and noise gate that work with the effect rather than against it.

Is it safe to use a voice changer on Discord?

A voice changer does not touch Discord's software. Discord just receives audio from a microphone, the same as with any headset, so there is nothing to inject and nothing for Discord to detect. What matters is how you use it. Do not use a changed voice to impersonate a real person, to harass anyone or to get around a ban, and respect the rules of each server, because some communities ask members not to use voice changers in certain channels. Mimicore's acceptable use policy says the same thing, and it applies to cloned voices too: only clone a voice that is yours or that you have permission to use.

Because the changing happens on your PC, your microphone audio is processed in memory while the voice is running and is not stored or sent anywhere. The sign-in and plan check use the internet, but your voice does not.
