How the virtual microphone works
An app can’t change what your real microphone sends to other programs. So Simple Voice Changer adds a second, virtual microphone: it writes the changed voice into it, and Discord or the game reads from it as if it were a normal microphone.
- Windows: the virtual device is VB-CABLE, a driver by VB-Audio (free, donationware) that Steam installs during installation. Windows may need one restart before it appears. In your app, pick CABLE Output (VB-Audio Virtual Cable) as the microphone, and never “CABLE Input” as your speaker.
- Linux and SteamOS: the sound server (PipeWire or PulseAudio) creates virtual devices on request, so no driver is needed. The app creates an output called “Simple Voice Changer Output” and a microphone called Simple Voice Changer Mic when it starts, as your normal user, and removes both when it quits. We watched this happen on a PipeWire 1.6.2 machine on 16 Sep 2026: the virtual microphone on Linux page has the details.
- On both: the Setup page’s Check it sends a short, quiet tone through the virtual microphone and says whether it arrives, or what to fix. Inside the app the signal goes: microphone → clean-up → neural or character voice, if one is on → the effect knobs → sound clips, music and App to Mic mixed in → the virtual microphone. Clips and music join after the effects, so they are never pitch-shifted.
What it can’t do
- Run on macOS, phones or consoles. Windows, Linux and SteamOS only.
- Speak for you. There is no text-to-speech.
- Sound like a named person or character out of the box. No such voices are included and there is no voice store. Character Voices runs RVC models you find yourself.
- Change how you speak. Every voice changes the sound; your words, pace, accent and expression stay yours, so a character is partly acting, and a changed voice doesn’t hide who you are.
- Run with no delay. A neural voice adds about 75 to 85 ms (on our test machines) and a character voice 0.3 to 0.5 seconds.
- Keep every word crisp with a neural voice. In a speech-to-text test about one word in six came out wrong at a natural pace, against one in fifty with the neural voice off: it smears some consonants.
- Sound unprocessed with the classic effects. Pitch and formant shifting move a voice a long way, but the result sounds processed.
- Get past another app’s noise filter by itself. Discord’s Voice Isolation, Krisp and similar filters can cut a changed voice or a sound clip; set them to off (Discord: Input Profile, Studio).
- Press keys in every game. The automatic push-to-talk key is ignored by games running as administrator (unless the app is too) and by some anti-cheat; on Linux it reaches X11 and XWayland programs only.
- Bring clips. The soundboard ships a few original starter sounds; there is no clip library.
Questions and answers
What is Simple Voice Changer?
A real-time voice changer and soundboard for Windows, Linux and SteamOS, made by Marduk Syndicate and sold on Steam. It changes your microphone’s voice as you speak and sends the result to a virtual microphone that Discord, Steam voice chat, OBS, Zoom and games can use as their input. It also plays sound clips, music and other apps’ sound into that microphone.
Is Simple Voice Changer free?
No. It is a one-time purchase on Steam. There is no subscription, no account, no DLC voices and nothing to unlock later. The price, and any discount, is shown on the Steam store page.
Does it need an internet connection or an account?
No. There is no account and no sign-in, and it works with the internet unplugged. Your voice, your sound clips and your settings stay on your computer. The app sends no telemetry.
Which operating systems does it run on?
Windows 10 and 11 (64-bit), Linux with a PipeWire or PulseAudio sound server, and SteamOS in Desktop Mode. The Linux and SteamOS version is a native build, not Windows software running through Proton. There is no macOS, mobile or console version.
Does it work on the Steam Deck?
In Desktop Mode, yes: it is the same native SteamOS build. Game Mode has not been verified, and the app has no Steam Deck compatibility rating.
How does the virtual microphone work on Windows?
On Windows the app uses VB-CABLE, a free virtual audio driver by VB-Audio (donationware) that Steam installs together with the app; Windows may need one restart before it appears. You pick “CABLE Output (VB-Audio Virtual Cable)” as the microphone in Discord or your game. The app’s Setup page sends a short, quiet tone through the cable and confirms that it arrives.
How does the virtual microphone work on Linux and SteamOS?
On Linux and SteamOS the app asks the sound server (PipeWire or PulseAudio) to create a virtual output and a virtual microphone when it starts, as your normal user, and removes them when it quits. No driver, no root access and no configuration files are involved. You pick “Simple Voice Changer Mic” as the microphone in your app.
Does it work with Discord?
Yes. Pick the virtual microphone as Discord’s input device. Set Discord’s Input Profile to Studio, because its Voice Isolation can remove a changed voice as background noise; the app’s own Noise Removal cleans the microphone instead. The app’s Setup page walks through Discord’s settings and shows when Discord is listening.
Does it use AI?
Two optional features do. The neural voices (200 voices, men and women, from the Beatrice 2 model) and Character Voices (RVC voice models you bring yourself) each run a small neural network on your own computer, offline. Both only change the sound of what you say. The ten classic effects are ordinary signal processing.
Can it make me sound like a specific person?
Not out of the box. It includes no voices of real people or characters: the neural voices are anonymous audiobook readers. If you load an RVC voice model you found yourself, you sound like that model, as good as the model is, while your words, timing and accent stay yours. Use only voices you have the right to use.
How much delay does it add?
A neural voice added about 75 to 85 ms on our test machines, and the app shows each voice’s delay. An RVC character voice adds about 0.3 seconds on a graphics card and about half a second on a processor, which people on a call will notice. The classic effects add less; we haven’t measured them precisely.
Does it need a graphics card?
No, except for Character Voices. The neural voices, classic effects, soundboard and music all run on the processor. For Character Voices a gaming graphics card of any brand is recommended, and a built-in test says whether your computer can run them.
Can it play music or another app into my microphone?
Yes. The Music page plays your own tracks into the call, ducked under your voice and never pitch-shifted, with hotkeys and a key per song. App to Mic sends what another program plays (Spotify, a browser, or your Discord friends) into the microphone; on Windows that needs Windows 10 version 2004 or later.
Do the hotkeys work in games?
Yes. They are global, they still fire while Shift or Ctrl is held, and push to talk only watches its key, so the game still receives it. The numpad, F13 to F24, media keys and punctuation keys can all be shortcuts. On Linux Wayland, hotkeys go through the desktop’s global-shortcuts service (KDE Plasma 6, GNOME 48 and later, SteamOS Desktop Mode) or need the user to be in the input group.
Does it touch my games?
No. Games and chat apps see Simple Voice Changer as an ordinary microphone, and it doesn’t touch game files or memory. Server and game rules still apply: many roleplay servers and competitive games ban voice changers, soundboards or music over voice chat.
Is it a Voicemod alternative?
For a voice changer, a soundboard and music under your voice on your own machine, yes: it is bought once, runs offline with no account, and runs natively on Linux, where Voicemod doesn’t run (its help centre listed Linux as “on our roadmap” when we checked on 16 Sep 2026). It is not a replacement if you want a store of licensed or celebrity voices: it has none.
