UnlockSFX generates game-ready sound effects from a text prompt, right inside the Godot editor. Describe a sound, and it's generated and imported straight into res://sfx/.

Features

• Two ways to generate — a full-featured right-hand dock, or right-click any folder in the FileSystem dock → "UnlockSFX: Generate here…" (Godot 4.3+) for a quick pop-up pointed at that folder.
• Variation banks — generate 2–8 variants and get an AudioStreamRandomizer .tres (no-repeats + pitch variance). Drag it onto an AudioStreamPlayer for instant non-repeating playback.
• Seamless loops — generate clips with no audible start/end for continuous ambient beds.
• MP3 or WAV — small and ship-ready, or uncompressed.
• Live credit balance and in-editor preview ("Listen").

License & rights

Every generated clip is royalty-free, cleared for commercial use, no attribution required (the only limit: don't resell the raw audio files). The dock shows a "Cleared to ship" card after each generation, plus a one-click Steam AI-disclosure snippet.

Note: The MIT license above covers the plugin code. The generated audio has its own royalty-free content license: https://www.unlocksfx.com/license

AI disclosure

Sounds are AI-generated. Each clip gets a hidden provenance sidecar recording the prompt, license, and AI origin.

Requirements

• Godot 4.3+ (the dock works on earlier 4.x; right-click Quick Generate needs 4.3+)
• A free UnlockSFX account + credits — create an API key at unlocksfx.com → Settings → API keys, paste it into the dock.
• Internet access (calls https://www.unlocksfx.com/api/v1)

Pricing: 1 credit per 5 seconds; variation banks get ~25% off and only charge for clips that succeed.
