# Popworks recorded sound effects

All effects are served locally. No audio is synthesized and no external service is contacted during play.

- **inflate.ogg**, **pop.ogg**: [Balloon Sounds](https://opengameart.org/content/balloon-sounds), AntumDeluge, CC0. Original recordings: balloon inflate by d.n.audio.uk; balloon pop by Gniffelbaf. Source files balloon_inflate_0.ogg and balloon_pop_0.ogg, downloaded 2026-10-26 unchanged. Source describes normalization to -6 dB, 44.1 kHz mono.
- **switch.ogg**, **bell.ogg**: rubberduck, [100 CC0 SFX](https://opengameart.org/node/85570), CC0. Existing local recorded-v2 switch_01.ogg and bell_01.ogg copied unchanged from the Stormglass sound library. Full provenance in ../stormglass/CREDITS.md.

Playback uses quiet gains and bounded excerpts at original pitch. Turbo shortens the air excerpt; it does not pitch-shift the recordings.
