About SFXForge AI

SFXForge AI is an AI sound effect generator for game developers. You describe a sound in plain words, such as "sci-fi airlock door, pressurized hiss" or "campfire crackle, seamless loop", and get back a royalty-free audio clip a few seconds later. It's built for the moment in game development when you know exactly which sound a scene needs, but no sound pack has it.

What it does

  • Generates sound effects from text. One-shots for impacts, UI, pickups and footsteps, and seamless loops for engines, ambience and fire, from 1 to 60 seconds long.
  • Works where you build your game. A dockable window inside the Unity editor saves clips straight into your project. A web version covers Godot, Unreal, GameMaker and any other tool. AI coding agents such as Claude Code and Codex generate sounds through our MCP server and REST API.
  • Keeps your sounds organized. Every sound you generate stays in your library, with folders, search and previews, in Unity and on the web.
  • Charges only for what you generate. There's no subscription. You buy a credit pack once and spend 10 credits per second of audio. New accounts get 30 free seconds to try it.

Licensing

Every generated sound comes with a royalty-free commercial license, so you can ship it in a commercial game without attribution. The details are in our Terms of Service. Sounds are generated with Stable Audio 3 from Stability AI, under the Stability AI Community License, on GPU infrastructure run for us by an infrastructure provider. Your prompts are not sent to the company that made the model.
