Voice changer for Discord
Talk to your server as a demon, a robot or a radio operator. VoiceFX changes your voice in the browser; a free virtual cable carries it into Discord as if it were a microphone.
Set it up: Discord step by step
Step 1 of 5
Install a virtual cable
Download VB-CABLE from vb-audio.com, unzip, run the setup as administrator, then restart your PC.
Why the cable?
Browsers are sandboxed: a web page can play audio to a speaker but cannot invent a new microphone. A virtual cable is a tiny driver that appears as both a speaker ("CABLE Input") and a microphone ("CABLE Output"). VoiceFX plays into one end, Discord listens to the other.
Discord settings that matter
- Noise suppression (Krisp): off. It treats robot and vocoder tones as noise and removes them.
- Echo cancellation and automatic gain control: off. They pump the volume up and down.
- Input sensitivity: set manually so the soundboard does not get cut off.
- Push to talk works as normal; bind it in Discord.

Voices that work well in Discord
Discord compresses voice with the Opus codec, which is kind to pitch effects and harsh on very quiet reverb tails. Strong, mid-heavy voices survive best: Deep Voice, Robot, Demon, Girl Voice and Walkie-Talkie for squad comms.
Want sound effects too? The Discord soundboard guide uses the same cable.

Questions
Can I use a voice changer on Discord for free?
Yes. VoiceFX is free and runs in your browser; the only other piece is a free virtual audio cable (VB-CABLE on Windows, BlackHole on macOS) so Discord can treat the processed audio as a microphone.
Why does Discord not hear the effect?
Usually Discord's input is still your real mic. Set Input Device to "CABLE Output" (or BlackHole), and in VoiceFX set "Send to" to "CABLE Input". If it is quiet or choppy, disable Krisp noise suppression, echo cancellation and automatic gain control.
Does it work in the Discord browser app?
Yes, but run VoiceFX and Discord in separate tabs or windows and still use the virtual cable as the Discord microphone. The desktop app is more reliable.
Does it work on Discord mobile?
Not directly. Phones do not allow browser audio to be routed into another app's microphone. Use a PC or Mac for voice chat.
Is using a voice changer on Discord allowed?
Discord does not ban voice changers, but servers set their own rules, and harassment or impersonation breaks Discord's Community Guidelines regardless of the tool.
Will my friends hear a delay?
The effect adds tens of milliseconds, far less than Discord's normal network delay, so friends will not notice. Avoid Bluetooth headsets, which add much more.
