One-shots vs. loops
For one-shot SFX — hits, clicks, pickups, whooshes — use 0.5 to 3 seconds and leave loop off, so the sound has a natural attack and tail. For beds like rain, engines or café chatter, pick 10 seconds or more and turn on Seamless loop.
Tips for better SFX prompts
Describe the source (“metal pipe”), the action (“dropped on concrete”) and the space (“in a large empty warehouse”). Add style words like “8-bit”, “cinematic” or “cartoon” to change the whole character of the sound.

FAQ
What is an SFX generator?
An SFX maker that creates sound effects from a text description instead of a stock library. You write “sci-fi door sliding open with a hiss” and get that sound, at the length you choose.
Can I make game sound effects?
Yes. Retro 8-bit blips, coin pickups, jumps, hits, UI clicks and magic spells all work well. Keep prompts short and specific for one-shot sounds, and keep them under 2 seconds.
Can the sounds loop?
Turn on Seamless loop for ambience, engines, rain or crowd beds. Loops can be up to 22 seconds and repeat cleanly in your editor or game engine.
Is it free?
New accounts get 18 free credits, enough for up to 18 short sounds. After that it’s 1 credit per 5 seconds of audio.
Can I use the SFX in commercial projects?
Yes, on any paid plan. Sounds made with free credits are for personal use.
