Retro Sound Effect Generator (Coin, Jump, Laser, Explosion)
Pick a preset or roll a random sound, tweak the pitch, slide and fade, and download a WAV for your prototype. Nothing is uploaded; the sound is generated in your browser.

How these sounds are made
Each effect is a simple oscillator (square, sawtooth, sine or noise) whose pitch slides over time and fades out. It is the same idea behind classic sfxr-style generators, which is why the results sound retro and work well for jam games and prototypes.
Generate ten variants and keep the one that fits. Layer two short sounds for a richer hit, and keep effect volume below your music.
When to use it
Prototyping before the real audio
Give jumps, pickups and hits a sound on day one; games feel broken without feedback, even in a grey-box prototype.
Game jams
Make every sound effect you need in a few minutes and stay inside the jam's rules on original content.
Retro and arcade games
The square, saw and noise waves are the same building blocks old consoles used, so they fit a pixel art game as they are.

Questions
The sounds are generated on your device from your own settings, so you are the author of what you download. Check the rules of any store or jam you submit to.
A mono 16-bit WAV at 22,050 Hz, which every engine imports.
Noise effects use random values on purpose. Click play again or download several takes.
Lower the volume, shorten the sustain and add a little fade. Square waves sound softer with a lower pitch; noise sounds softer when it is shorter.
Drag the file into the project. In Unity add an AudioSource and play it; in Godot use an AudioStreamPlayer node. Both import WAV as it is.
