AI Sound Effect Generator
An AI sound effect generator turns a written description into an audio file. You type what the sound is — a door, a footstep, a weapon, a UI click — and the engine synthesises it as a new recording rather than looking one up in a library, so the result is not something anyone else has already used.

How it works
- 1
Describe the sound in plain words. Say the material, the space and the action: "heavy wooden door slams in a cathedral" beats "door".
- 2
Set the length between 1 and 30 seconds, and ask for up to four variants so you can pick the take instead of re-running the prompt.
- 3
Audition each take in the browser, then download the one you want, or send it straight to a timeline, a canvas or a game audio bank.
Example prompts
Three prompts that work well. Open the generator and paste one in.
- heavy wooden door slams shut in a stone cathedral, long tail
- single footstep on wet gravel, close mic, no reverb
- retro arcade power-up, bright, rising, half a second
What you give it
A text prompt, and three optional knobs: length in seconds, prompt influence, and how many variants to make in one run. A seed can be set if you want the same prompt to return the same take again. Nothing is uploaded, so there is no file size to worry about.
What you get back
One audio file per variant, in the container and sample rate you chose on the form. A single run of four variants gives you four separate files, each auditioned in the browser before you download it.
WAV, FLAC and MP3, at 44.1 or 48 kHz and 16 or 24-bit. You pick the container and the rate on the form before you run it.
Who it is for
Game developers who need twenty versions of one impact instead of one. Video editors filling a cut where the production audio has nothing. Sound designers building a layer that does not exist in any library — a creature, a machine, an interface that has not been made yet.
What it costs
Two credits per take. The free plan includes 25 credits a month, which is roughly twelve takes, and the estimate is shown on the form before you run anything.
Every run is a queued job. It holds its credit estimate while it works and settles to the real cost when it finishes; if it fails or you cancel it, the hold is released in full. You see the estimate before you spend anything.
Licence and ownership
Everything you generate is royalty-free for commercial use — client work, monetised video, games you sell, ads. No per-use fee and no attribution requirement. Generations are yours; uploads stay private by default, and the inputs to the isolator and splitter are deleted automatically.
Common questions
- How long can a generated sound effect be?
- Between one and thirty seconds. For anything longer, generate the parts separately and lay them out in the Timeline Studio, which is included on every plan — a thirty-second limit on a single take is not a thirty-second limit on a finished sound.
- Can I get several versions of the same sound?
- Yes. Ask for up to four variants in one run and you get four separate files from one prompt. That is the normal way to use it: a game that plays the same impact two hundred times needs variation, not one perfect take.
- Can I sell a game that uses these sounds?
- Yes. Generated audio is royalty-free for commercial use with no attribution requirement, which covers games you sell, client work, monetised video and ads. You own what you generate.
