Voice changer for Mac
VoiceChange for Mac is a free 11 MB app for Macs with Apple Silicon (M1 or later, macOS 11 or newer). It changes your voice live and sets up the free BlackHole virtual microphone in one step, so Discord, Zoom, OBS and games can use the new voice.
Many voice changers are Windows-only. This one is built for the Mac and signed and notarized by Apple.
How to use a voice changer in Mac apps
- Download VoiceChange free from the desktop app page (Windows, macOS on Apple Silicon, or Linux) and open it.
- Click Set up virtual mic. The app installs a free virtual microphone in one step (BlackHole on Mac, VB-CABLE on Windows, a PipeWire/PulseAudio virtual mic on Linux).
- Pick a voice and switch it on with the power button or Space. Talk and watch the trace to check it works.
- In Discord, Zoom, OBS or your game, choose BlackHole 2ch as the microphone. For apps without a microphone setting, set the input in System Settings → Sound.
- Talk. The people you are with hear the new voice about 25 ms after you speak, which is too short to notice.
System requirements
- macOS 11 Big Sur or newer.
- A Mac with Apple Silicon (M1, M2, M3, M4 or later). Intel Macs aren't supported.
- Microphone access, which macOS asks for the first time you switch a voice on.
No Mac with Apple Silicon?
The online voice changer works in Safari and Chrome on any Mac, including Intel Macs, for recordings, text to speech and live effects that you hear yourself.
Questions
Is it free?
Yes. The VoiceChange desktop app and its voices are free, with no account, trial or watermark.
Will it slow down my game?
No. It uses about a quarter of one CPU core and no graphics card, so games keep their frame rate. If your computer is busy, the Steadier setting uses less CPU for 13 ms more delay.
Is my voice uploaded anywhere?
No. The AI runs on your own computer, so your audio never leaves it.
Does it work with FaceTime?
On recent macOS versions you can pick FaceTime's microphone from its Video menu; choose BlackHole 2ch there.
