FAQ
What impact sounds can I make?
Anything in this family — hits, explosions, crashes, slams, and bone-crunching blows. Describe the specific sound you need and choose a game style so it matches your art direction. If you want options, generate a variation bank of 2–8 takes and pick your favorite.
Are these impact sound effects royalty-free?
Yes. Sounds you generate on UnlockSFX are royalty-free and licensed for commercial use in your games — no attribution required. You just can't resell the raw audio files on their own as a sound library.
What formats can I download?
MP3 by default, or WAV when you need uncompressed audio. Clips are short and game-ready, so they drop straight into Unity, Godot, Unreal, or GameMaker.
How much does it cost?
You get 3 free credits to start. After that, credit packs are one-time purchases from $5 — no subscription. A clip costs 1 credit per started 5 seconds, and credits never expire.
