Who It's For

Why Gaming & Metaverse Development choose this tool

🎯
Built for
Game developers and streamers needing a versatile toolkit for real-time voice modulation, character voice generation, and audio post-production.
In-Depth Overview
For game developers, Supertone addresses multiple audio needs within a single ecosystem. Its standout feature, 'Shift', is a real-time voice changer perfect for adding immersion to multiplayer games, role-playing in VRChat, or creating engaging streaming content—the site specifically calls out its use in FPS lobbies. This directly enhances the player experience. For pre-production, 'Play' serves as a powerful text-to-speech engine. Developers can rapidly prototype NPC dialogue, test narrative scripts, and generate high-quality temporary or even final voice lines without the immediate cost and logistics of hiring voice actors. The quality is backed by collaborations with professional talent like Jeong Jae-heon, who voiced characters in the Korean dubs of 'League of Legends' and 'Stellar Blade'. Finally, for post-production, the 'Clear' and 'Air' plugins provide accessible audio cleanup. 'Clear' uses a simple three-knob interface to de-noise and de-reverb dialogue, while 'Air' matches ADR to production audio. This is invaluable for indie studios or smaller teams aiming for professional-grade audio on a budget.
