Spooky Sound BoardSound credits & licences
This page is the complete list of what is inside the app: all 100 sounds with the identifier the
app stores them under, the open-source libraries it is built on, and the licences that apply.
It is generated from the app's own catalogue (SoundCatalog.kt), which the release
build refuses to ship if it disagrees with the audio files in res/raw — so a
sound cannot appear in the app without appearing here.
Where the sounds come from
Every sound in this release is CloudyNI in-house sound design: synthesised and mixed for this app under the licence Synthesised for CloudyNI — royalty-free, exclusive. Nothing is sampled from a commercial library, no third-party recording is redistributed, and no attribution obligation is carried by any individual clip.
The audio is generated reproducibly by scripts/generate-placeholder-sounds.ps1, and
scripts/verify-audio-assets.ps1 checks every file. The identifiers below are
permanent: replacing a placeholder recording with a real one later changes the file and its
licence line, never the identifier — so favourites and the Haunted Doorway rotation survive an
audio update.
If a future release does bundle a CC0 recording from Freesound, the Sonniss GDC bundle or Mixkit, the clip's own source and licence will be written into the catalogue and will appear in the table below before that build ships.

Fonts
No fonts are bundled with the app. It uses the device's own system font with the Material 3 type scale, so the text matches the rest of your phone and the download stays small. This website, by contrast, uses Outfit and JetBrains Mono under the SIL Open Font License via Google Fonts, with a system-font fallback if that request fails.
Open-source libraries
The Android app is built on the following, each used under its own licence:
- Jetpack Compose & Material 3 — Apache License 2.0 — © The Android Open Source Project
- AndroidX (Lifecycle, Navigation, DataStore) — Apache License 2.0 — © The Android Open Source Project
- AndroidX Media3 (ExoPlayer) — Apache License 2.0 — © The Android Open Source Project
- Hilt / Dagger — Apache License 2.0 — © Google LLC
- Kotlin & kotlinx.coroutines — Apache License 2.0 — © JetBrains s.r.o.
- Google Mobile Ads SDK & User Messaging Platform — Google APIs Terms of Service
- Google Play Billing Library — Google APIs Terms of Service
Apache License 2.0 and the SIL Open Font License both require the licence text to travel with the software; the full texts are available from each project, and the same list is shown inside the app under Settings → Open-source licences.
Something looks wrong?
If a sound is credited incorrectly, or you believe one of your recordings has been used without permission, email support@cloudyni.com with the identifier from the table and we will investigate, remove the clip and republish. We would much rather fix a credit than argue about one.
