Type what you want to hear and get a usable sound effect out the other side. SFX Generator is for the long tail of "I need a pshhh, a thunk, a low whoom" — the sounds you'd otherwise spend an evening trawling freesound for. Describe it in words, pick a duration, and the AI hands you back a clip ready to drop into your game.

It's the audio equivalent of "stop hunting, just generate it."

Features

  • Text-to-SFX. Describe the sound — "metal door slam with a wet reverb tail," "8-bit coin pickup," "footsteps on wet leaves" — and the generator delivers a clip that matches.
  • Duration control. From a 100ms blip to a full minute of ambient drone. Dial it in for the use case — UI clicks stay tiny, ambience loops can stretch.
  • Ambience mode. Flip a toggle to swap the model's mood from "short, punchy effect" to "long, evolving atmosphere." Same prompt, very different result.
  • Batches of up to 4 samples. Same prompt, multiple takes. Pick the best, discard the rest — much faster than re-rolling one at a time.
  • Optional seed. Lock a seed and the same prompt always produces the same clip. Tweak words, re-roll variations — when you find one you like, save the seed.
  • History sidebar. Every batch you've generated, scrolled into easy reach. Re-open any past prompt and pick up where you left off.
  • Saved to your VFS. Each sample lands as a real audio file in your workspace — moveable, renameable, droppable straight into the Code Editor or any other tool that takes audio.
  • Multiple windows. Generate the explosion, the menu blips, and the ambient background loop in parallel — no queue, no waiting on a single window.

What you walk away with

  • Sound effects that fit your game's vibe, not someone else's library.
  • A growing personal SFX library in your VFS, organised the way you organise everything else.
  • A serious shortcut around the "audio is the bit I keep putting off" problem most solo devs run into.

Heads up: generating sounds uses credits — they pay for the upstream AI compute. The cost shows before you commit.

A game without sound feels half-finished, and the gap between "no SFX" and "any SFX" is huge. This tool collapses the time cost of that step to almost nothing.
