Gacha Reveals sound effects: 12 free sounds from one prompt
Play 12 gacha reveals 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 gacha or card-pack game: sparkly, suspenseful reveals that grow bigger with each rarity tier. Save each sound as a WAV file in a sounds folder, named like this: - pack-tear: A foil card pack tearing open: a quick crinkly noise rip, under half a second. - chest-shake: A treasure chest rattling and shaking with suspense before it opens, wooden knocks and a rising hum, about one second. - glow-buildup: A rising shimmering swell of sparkles building suspense before a reveal, about two seconds, ending abruptly. - card-flip: A crisp paper card flipping over to reveal its face, a short airy snap under a quarter second. - reveal-common: A plain, modest single soft chime for revealing a common item, short and neutral, under half a second. - reveal-rare: A bright two-note bell chime with a light sparkle for revealing a rare item, about one second. - reveal-epic: A rich rising three-note bell arpeggio with shimmering sparkles for revealing an epic item, about one and a half seconds. - reveal-legendary: A huge golden reveal: deep boom, soaring bright chord and long sparkling tail for a legendary item, about three seconds. - duplicate: A gentle, slightly flat two-note descending blip for pulling a duplicate item, under half a second. - dupe-convert: A duplicate dissolving into currency: a quick sparkly crunch followed by tiny coin ticks, about one second. - rarity-upgrade: A reveal glow jumping up a rarity tier mid-animation: a sharp rising zing and bright flash, about one second. - multi-pull: A rapid rhythmic series of ten soft card whooshes for a ten-pull, each a little higher, about two seconds. Make them sound like they belong to the same game.”
What happened
Claude
All 12 sound effects are in sounds/ as stereo WAVs (44.1 kHz, 16-bit). I couldn't listen to them; I checked them with measurements and spectrogram images instead, so please give them a listen.
We gave the prompt above to a fresh Claude Code session in an empty folder, with no skills and no extra tools. It wrote a small program that makes every sound from scratch, and it took about 3 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, where you can search all packs at once. They are free to use in your games, commercial or not.
