23 short 44.1 kHz WAV sounds for menus and arcade games: clicks, hovers, confirm, cancel, errors, coin, power up/down, jump, laser, hit, explosion, notification, typewriter, menu open/close. CC0, so use them anywhere, no credit needed. Synthesised procedurally in Python from basic waveforms; no samples or AI audio models used. Made with the help of an AI assistant (the code was written by AI); checked and curated before release.
