Free tool

Sound effect generator, click, play, save.

Press a button to make a new coin pickup, jump, laser, explosion, power-up, hit, blip, click or whoosh, each one a fresh variation. Keep pressing until one fits, nudge it with Mutate, or shape it yourself: wave type, pitch slide, vibrato, a pitch jump, attack and decay, filters, repeat and a retro bit crusher. Save it as a WAV for your game, app or video.

How it works

Synthesised, not sampled.

01 / Presets

A new roll each time

Each button picks fresh settings within a range that sounds like a coin, a jump or a laser, so no two clicks are the same.

02 / Controls

Every knob there

Pitch, slide, vibrato, a jump in pitch, the envelope, filters, repeat and a bit crusher, the controls classic retro sound tools use.

03 / Yours

No samples, no licence

Each sound is computed from numbers in your browser, so there is nothing to credit and nothing to clear.

Questions

Good to know.

Can I use these sounds in my game?

Yes. The sounds are generated in your browser from your settings, not taken from a library, so you can use them in commercial games, apps and videos.

What format are the files?

WAV, 16-bit, 44.1 kHz, mono, which every game engine and editor opens.

How do I get a retro 8-bit sound?

Use the Square or Noise wave, keep it short, and add some Bit crush. The Coin, Jump and Blip presets start there.

What does Mutate do?

It nudges a few settings at random, so you can explore close variations of a sound you almost like.

Can I go back to an earlier sound?

Yes. The sounds made this session are listed; click one to bring it back.
