FAQ
Practical answers for developers evaluating UnlockSFX.
Can I use generated sounds in my game?
Yes. UnlockSFX is designed for practical use in game projects.
Can I use sounds commercially?
Yes. Generated sounds are yours to use in commercial and personal projects, royalty-free, no attribution required. See our License page.
How do credits work?
A clip costs 1 credit per started 5 seconds, so most sound effects cost 1 credit. Variation banks of 2–8 takes are about 25% off. You get 3 free credits at signup, packs are one-time purchases, and credits never expire.
Do I need to hire a sound engineer?
No. UnlockSFX helps you create custom game SFX without a dedicated audio specialist.
Can I generate sounds for Unity, Unreal, Godot, and Roblox?
Yes. Downloads are standard MP3 or WAV files that work in any engine. Godot and Unity also have free plugins that generate sounds right inside the editor.
Is there a version without AI?
Yes. UnlockSFX Forge is an offline Windows app ($9.99, one-time) with a retro sound synth and an editor for your own recordings. No AI, no credits, no internet needed.
Can I use these outside of games — like YouTube videos or podcasts?
Absolutely. UnlockSFX is built for game devs first, but the sounds are royalty-free, so they work great for YouTube videos, podcasts, streams, and other creator projects too — whooshes, transitions, impacts, stingers, and more.
Can I resell generated sounds as a sound pack?
No. Use them inside your own projects, but don't resell or redistribute the raw files on their own or bundle them into a sound pack or library.
What file formats are supported?
MP3 or WAV. MP3 is small and ship-ready; WAV is uncompressed, with no compression artifacts.
Why are there no unlimited plans?
Credits keep generation fair, affordable, and sustainable.
