Arcade Sports sound effects: 12 free sounds from one prompt
Play 12 arcade sports 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 fast arcade ball sports game: bouncy, energetic and crowd-pleasing. Save each sound as a WAV file in a sounds folder, named like this: - ball-kick: A solid kick on a ball, a punchy round thump with a quick airy pop, under a quarter second. - ball-bounce: A rubber ball bouncing on a hard court, a short springy boing-like thud. - racket-hit: A ball struck with a racket, a crisp tight ping-thwack, under a quarter second. - net-swish: A ball swishing through a net, a soft quick rush of filtered noise, under half a second. - whistle: A referee whistle blast, a shrill bright warbling tone, about half a second. - ball-whoosh: A fast ball flying past, a quick whoosh of noise that rises then falls, under half a second. - crowd-cheer: A crowd roar made of swelling broad noise with bursts of excitement, seamless loop of about six seconds. - goal-horn: A celebratory goal horn, a loud deep buzzy tone held for about two seconds. - score-tick: A scoreboard point added, a short bright digital tick with a tiny upward chirp. - power-meter: A shot power meter filling up, a smooth rising tone that loops upward, about one second. - buzzer-end: An end-of-period buzzer, a harsh flat buzz tone held for about one and a half seconds. - victory-fanfare: A winning-team fanfare, a bright upbeat four-note rising melody with a final held chord, about two seconds. Make them sound like they belong to the same game.”
What happened
Claude
All 12 sounds are in sounds/ as WAV files (44.1 kHz, 16-bit, mono). I made them from scratch with a pure-Python synth script at tools/make_sfx.py. I couldn't listen to them, so I checked them by numbers only: lengths, peak and average levels, no clicks at the start or end, and that the two loops join cleanly. They still need a listen in the game.
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 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, where you can search all packs at once. They are free to use in your games, commercial or not.
