8-bit platformer sound effects: 11 free sounds from one prompt
Play 11 8-bit platformer sound effects that Claude Code made from one prompt. Copy any sound's prompt, or download the pack as WAV files.
What we asked“Make a sound effect pack for a retro 8-bit platformer, in the style of NES-era chiptune sound. Save each sound as a WAV file in a sounds folder, named like this: - jump: A short rising square-wave blip for a jump, quick and springy. - double-jump: A second, higher jump blip with a tiny flutter, so it feels lighter than the first jump. - land: A soft, very short low thud for landing on the ground. - coin: A bright two-note coin pickup, the second note higher, under a quarter second. - power-up: A fast rising arpeggio for grabbing a power-up, cheerful and about one second long. - stomp: A punchy squash sound for stomping on an enemy, with a quick downward pitch drop. - hurt: A harsh, short buzzing hit for taking damage. - death: A falling, wobbling tone for losing a life, about one second. - checkpoint: A friendly three-note chime for touching a checkpoint flag. - spring: A boingy pitch-bending spring bounce. - level-clear: A short victory jingle for finishing a level, about two seconds, ends on a major chord. Make them sound like they belong to the same game.”
What happened
- Wrote one Python script that imitates the NES sound chip: square waves, a stepped triangle bass and noise
- Made all 11 sounds in the same key, C major
- Measured pitch and loudness over time to check each sound rises, falls or wobbles as asked
- Smoothed the end of the power-up and fixed the bass in the victory jingle
Short and loud, like the games they copy. The jump and double jump are built to be heard together: the second one starts higher and is a little thinner, so the player hears the difference without thinking about it.
The victory jingle cheats a little. The real chip could only play two square-wave notes at once, and the final chord needed three.
We gave the prompt to a fresh Claude Code session in an empty folder, with no skills and no extra tools. It took under 2 minutes. Claude can’t hear, so it checked the sounds by measuring them. Press play and judge them yourself.
Every sound is also in the sound effects library, next to the sounds from the other packs. They are free to use in your games, commercial or not.
