# Check:
- Preview before download

## ElevenLabs Text-to-Sound-Effects

### API Generation

```javascript
await mcp__elevenlabs__text_to_sound_effects({
  text: "Heavy wooden door creaking open slowly",
  duration_seconds: 3,
  loop: false,
  output_format: "mp3_44100_128"
})
```

### Effective Prompts

```
# Be specific and descriptive
GOOD: "Footsteps on gravel path, slow pace, approaching from distance"
BAD: "walking sound"

GOOD: "Old typewriter keys clacking rhythmically with carriage return"
BAD: "typing"

GOOD: "Thunder crash followed by rain gradually increasing"
BAD: "storm"

GOOD: "Coffee machine brewing with steam hissing and dripping"
BAD: "coffee sound"
```

### Duration Guidelines

```
Short SFX: 0.5-2 seconds (impacts, clicks)
Medium SFX: 2-5 seconds (actions, movements)
Loop-able: 3-5 seconds (ambience, backgrounds)

Maximum: 5 seconds
```

## Sound Library Organization

### File Naming Convention
