Antinode Shift
Real-time AI voice changer with 100+ character voices, no GPU required
About Antinode Shift
Antinode Shift (formerly Supertone Shift) is a desktop real-time AI voice changer for VTubers, streamers, and gamers. It converts your speech into one of 100+ character voices, lets you blend a character with your own voice and tune parameters like pitch, and runs on a CPU without a dedicated GPU. Supertone transferred the product to Antinode Audio, which now operates it.
Pros & Cons
Pros
- Built for VTubers, with character voices designed for persona work
- Runs on CPU, so it leaves the GPU free for avatar tracking and game capture
- Perpetual per-voice licenses let you own a character voice outright
- Low entry price with a usable free tier
Cons
- Desktop only (Windows 10+ 64-bit and macOS)
- No custom voice cloning from your own recordings; you pick and tune library voices
- Ownership changed from Supertone to Antinode Audio, so roadmap is less established
