The retro sound effects generator creates 8-bit style sounds through pure synthesis, with no recording or sound bank involved, just like classic tools such as sfxr. Choose between 8 sound types (coin, jump, laser, explosion, hit, power-up, select and game over), listen to them instantly, and press "random variation" as many times as you like until you find the exact sound you're after within that same style. Once you like the result, download it as a WAV file ready to use in your game, animation or project. All the sound is generated mathematically with the Web Audio API directly in your browser.
