# SFX — Audio Assets
|
|
|
|
World sound effects: footsteps, environmental events, impacts. Event-driven, often positional (AudioStreamPlayer2D).
|
|
|
|
## Generation Approach
|
|
|
|
Mixed methods depending on duration and character:
|
|
- Footsteps: SAO generation (>200ms) or hybrid (generate longer clip, extract best transient)
|
|
- Future environmental SFX (doors, machinery events): SAO or foley recording
|
|
- Post-processing: normalize, trim, ensure clean attack/release
|
|
|
|
## Assets
|
|
|
|
| ID | Filename | Status | Bus | Method | Duration | Prompt/Notes | Sprint |
|
|
|----|----------|--------|-----|--------|----------|-------------|--------|
|
|
| SFX-001 | `sfx_footstep_metal_walk.ogg` | done | Player Actions | SAO hybrid | 0.3s | Single footstep on metal grating. Walk pace. SAO 5s/100 steps/CFG 8, best transient trimmed at 2.42s, LUFS -16 normalized. | S10 #327 |
|
|
| SFX-002 | `sfx_footstep_metal_run.ogg` | done | Player Actions | SAO hybrid | 0.3s | Faster footstep, sprint pace. Louder — player is broadcasting position (D-053 acoustic footprint). SAO 5s/100 steps/CFG 8, best transient trimmed at 1.03s, LUFS -16 normalized. | S10 #327 |

## Detailed Entries
|
|
|
|
### SFX-001: sfx_footstep_metal
|
|
- **Sonic family:** organic (physical world)
|
|
- **Bus rationale:** Player Actions — this is feedback on YOUR movement, not world information. NPC footsteps (future) go on World SFX.
|
|
- **Stance implications (D-053):** Walk = normal volume. Sprint variant (SFX-002) = louder. Careful = quieter variant (future asset). Crouch = near-silent variant (future asset).
|
|
- **Integration:** Triggered by player movement tick. Positional (AudioStreamPlayer2D at player position) — maps to camera-relative stereo per D-018.
|
|
- **Cross-reference:** D-038 (#5), D-053 (movement stances as acoustic decisions)
|
|
|
|
## Future Expansion
|
|
|
|
SFX will grow significantly with:
|
|
- NPC footstep variants (by surface type, stance) → World SFX bus
|
|
- Door open/close, machinery activation → World SFX bus
|
|
- Combat impacts, weapon sounds → Player Actions bus
|
|
- Environmental events per planet/biome
|
|
- NPC conversation murmur (event-driven, point-source) → World SFX bus
|
|
|
|
When this file exceeds ~50 entries, split by domain:
|
|
- `sfx-movement.md` (footsteps, stance variants)
|
|
- `sfx-environment.md` (doors, machinery, weather)
|
|
- `sfx-combat.md` (weapons, impacts)
|
|
- `sfx-conversation.md` (murmur, vocal events)
