One-shots for games and edits, risers and hits for trailers, loops for ambience — set the length, generate, download. 0/450 Length5.0s Prompt influence30% Seamless loop (for ambience and backgrounds)1 credit per 5 seconds · MP3, 44.1 kHz · only charged when it's done ## 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. ## What you can make ### Whoosh & Transition Swooshes, swipes and risers for video edits and title cards. ### Video Game Coins, power-ups, jumps, level-ups and retro 8-bit blips. ### UI & Notification Clicks, pops, chimes and alerts for apps and interfaces. ### Nature & Ambience Rain, wind, forests, oceans and loopable backgrounds. ### Horror Creaks, whispers, drones and jump-scare stingers. ### Sci-Fi Lasers, spaceship engines, robots and futuristic interfaces. ### Cartoon Boings, slide whistles, pops and comedic hits. ### Impacts & Explosions Hits, punches, crashes and cinematic booms. ### Magic & Fantasy Spells, sparkles, portals and enchanted shimmers. ### Footsteps & Foley Footsteps, cloth, doors and everyday foley. ### Animals Dogs, cats, birds, horses and wildlife. ### Crowd & Applause Applause, cheers, laughter and busy rooms. ## 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. ## Make your first voiceover free 18 credits on sign-up, no card. Gemini 3.1 Flash voices with accent, style and pace controls. Start now
