Turn a text description into any sound with this free AI sound effect generator. Describe what you want — rain on a roof, a sci-fi laser, a cinematic whoosh, footsteps on gravel, an 8-bit game blip — set the length, and download a royalty-free WAV. Powered by Stable Audio, no signup and no watermark.
It’s perfect for videos, games, podcasts, streams and music production when you need a specific sound you can’t find in a library.
AI Sound Effect Generator
Create any sound effect from a text prompt with AI — rain, explosions, sci-fi lasers, footsteps, whooshes, game blips and more. Describe the sound, set the length, and download a royalty-free WAV. Free, no signup.
How it works & privacy: your prompt is sent to our AI audio server (Stable Audio Open) to generate the sound — no files are uploaded and nothing is stored. Sounds are royalty-free for your projects. Free: 3 generations/day. The first sound after a quiet spell can take a minute or two while the AI warms up; it’s much faster after that. Need a full song instead? Try Solmi.
How to generate a sound effect
- Describe the sound. Be specific — source, action, material, environment and intensity all help (e.g. “heavy rain on a tin roof with distant thunder”).
- Set the length from 1 to 30 seconds — a short stinger or a longer ambience bed.
- Generate. The AI creates your sound in about 15 seconds (a little longer for the first one while the model warms up).
- Preview and download a royalty-free WAV.
How to write a good sound prompt
The more detail you give, the better the result. Try including:
- Source & action — “a heavy wooden door creaking open”.
- Material & environment — “on metal”, “in a cave”, “outdoors in wind”.
- Intensity & distance — “soft and distant”, “loud and close”, “gentle”.
- Style — “cinematic”, “retro 8-bit”, “realistic”, “sci-fi”.
Generate a few variations and pick the best — each generation is a little different.
What you can use it for
- Video & film — whooshes, impacts, ambiences and transitions.
- Games — jumps, coins, UI blips, explosions, power-ups.
- Podcasts & streams — stingers, alerts and background beds.
- Music production — risers, foley, textures and one-shots to layer in.
Cleaning up or shaping the result? Trim and convert with Extract Audio, shape tone with the Online Equalizer, or add space with the reverb tool. Need a full track instead of a sound effect? Generate original AI music with Solmi.
Free & royalty-free
Every sound you generate is free to make and royalty-free to use in your own projects, with no watermark. Generation is free for 3 sounds per day; your prompt is sent to our AI server and nothing is stored.
Frequently asked questions
How do I generate a sound effect from text for free?
Describe the sound, set a length, and click Generate. Our AI Sound Effect Generator creates a royalty-free WAV free, with no signup — 3 sounds a day.
Are the sounds royalty-free?
Yes — the sounds you generate are royalty-free to use in your own videos, games, podcasts and music, with no watermark.
How long can the sound be?
From 1 to 30 seconds — short stingers and one-shots, or longer ambience beds and loops.
Why did the first sound take longer?
After a quiet period the AI model needs a minute or two to warm up; once it’s running, generations take about 15 seconds.
What can it make?
Almost any sound you can describe — weather, impacts, whooshes, footsteps, machines, UI blips, sci-fi effects, ambiences and more. It’s best at sound effects and textures rather than full songs.
