Palette
See palette.md for the sonic identity: two sonic families (insert-tech / organic), station palette (functional warmth), generation approach, bus architecture.
Generation Tools
- Stable Audio Open: Self-hosted, >200ms organic sounds. ~47s ceiling per generation.
- Manual synthesis: <200ms insert-tech sounds. Audacity / Python oscillator.
- Post-processing: LUFS normalization, EQ carving, crossfade loops (3-5s overlap).
Bus Architecture
5 player-facing buses (see palette.md for full spec):
| Bus | Content |
|---|---|
| Music | Future — empty |
| Ambient | Station hum, zone overlays |
| World SFX | NPC footsteps, doors, conversation murmur |
| Player Actions | Player footsteps, combat |
| UI Sounds | Cursor, implant, chimes, recognition |
