AI sound effects, inside the Unity Editor
UnlockSFX is a Unity package that generates royalty-free, game-ready sound effects from a text prompt, right inside the Editor. Variation banks, seamless loops, WAV/MP3 — imported straight into your project.
We've submitted UnlockSFX to the Unity Asset Store and it's currently in review. Until it's live you can install it from GitHub in under a minute — the steps are below.
What you can do
Generate in the Editor
Open the UnlockSFX window and dock it anywhere — the full workflow lives there: prompt, duration, format, variants, looping, a live credit balance, and a Listen preview.
Right-click Quick Generate
Right-click any folder in the Project window and pick “UnlockSFX: Generate here…” to drop a sound straight into it.
Variation banks
Generate 2–8 variants in one pass and drop them into an Audio Random Container (Unity 6) for no-repeat, pitch-varied playback — instant variety from a single prompt.
Seamless loops
Generate clips with no audible start or end for ambient beds and engine hums that loop forever.
Cleared to ship
Every clip is royalty-free for commercial use with no attribution. One-click Steam AI-disclosure snippet and a provenance record included.
WAV or MP3
Uncompressed WAV with no artifacts, or small ship-ready MP3. Clips import as AudioClips automatically when saved inside Assets/.

- Internet access — the Editor calls the UnlockSFX API to generate your sounds.
Unity plugin FAQ
How do I install UnlockSFX in Unity?
Two ways today: add it through the Unity Package Manager with “Add package from git URL,” or download and import the .unitypackage from the GitHub Releases. Then open Window → UnlockSFX. A one-click install from the Unity Asset Store is on the way.
Which Unity versions are supported?
Unity 2021.3 LTS and newer is recommended; the window works across recent Editor versions. The Audio Random Container output needs Unity 6 — on older versions you still get the individual variation clips to wire up yourself.
Are the sound effects royalty-free?
Yes. Every clip you generate is cleared for commercial use with no attribution required — the only limit is that you cannot resell the raw audio files on their own. The plugin also gives you a one-click Steam AI-disclosure snippet.
Is the plugin free?
The package itself is free. Generating sounds uses credits from your UnlockSFX account — roughly one credit per five seconds of audio, and you get free credits to start.
What audio formats can I export?
WAV or MP3. Sounds saved inside Assets/ import automatically as AudioClips; you can also save to any folder outside the project as raw files.
