# ElevenLabs Sound Effects

Generate sound effects from text descriptions via [inference.sh](https://inference.sh) CLI.

![Sound Effects](https://cloud.inference.sh/u/4mg21r6ta37mpaz6ktzwtt8krr/01jz01qvx0gdcyvhvhpfjjb6s4.png)

## Quick Start

> Requires inference.sh CLI (`belt`). [Install instructions](https://raw.githubusercontent.com/inference-sh/skills/refs/heads/main/cli-install.md)

```bash
belt login

# Generate a sound effect
belt app run elevenlabs/sound-effects --input '{"text": "Thunder rumbling in the distance"}'
```


## Parameters

| Parameter | Type | Description |
|-----------|------|-------------|
| `text` | string | Description of the sound effect (max 1000 chars) |
| `duration_seconds` | number | Duration 0.5-22 seconds (optional, auto if omitted) |
| `prompt_influence` | number | 0-1, how literal to interpret prompt (default: 0.3) |

## Examples

### Cinematic Effects

```bash
# Epic trailer hit
belt app run elevenlabs/sound-effects --input '{"text": "Cinematic braam, deep bass impact"}'

# Suspense drone
belt app run elevenlabs/sound-effects --input '{
  "text": "Dark atmospheric drone, tension building, horror",
  "duration_seconds": 10
}'

# Whoosh transition
belt app run elevenlabs/sound-effects --input '{
  "text": "Fast cinematic whoosh transition",
  "duration_seconds": 1.5
}'
```

### Nature & Environment

```bash
# Rain
belt app run elevenlabs/sound-effects --input '{
  "text": "Heavy rain on a tin roof with occasional thunder",
  "duration_seconds": 15
}'

# Forest ambience
belt app run elevenlabs/sound-effects --input '{
  "text": "Forest ambience with birds chirping and gentle wind",
  "duration_seconds": 20
}'

# Ocean waves
belt app run elevenlabs/sound-effects --input '{
  "text": "Ocean waves crashing on a beach, calming",
  "duration_seconds": 15
}'
```

### Game Audio

```bash
# Power-up
belt app run elevenlabs/sound-effects --input '{
  "text": "Retro game power-up sound, ascending tones",
  "duration_seconds": 1
}'

# Explosion
belt app run elevenlabs/sound-effects --input '{
  "text": "Sci-fi laser explosion, futuristic",
  "duration_seconds": 3
}'

# UI click
belt app run elevenlabs/sound-effects --input '{
  "text": "Soft UI button click, subtle and clean",
  "duration_seconds": 0.5
}'
```

### Everyday Sounds

```bash
# Doorbell
belt app run elevenlabs/sound-effects --input '{"text": "Classic doorbell ring"}'

# Typing
belt app run elevenlabs/sound-effects --input '{
  "text": "Mechanical keyboard typing, fast, clicky",
  "duration_seconds": 5
}'

# Notification
belt app run elevenlabs/sound-effects --input '{
  "text": "Pleasant notification chime, positive",
  "duration_seconds": 1
}'
```

## Prompt Influence

Control how literally the model interprets your description:

| Value | Effect | Best For |
|-------|--------|----------|
| 0.0 | Very loose interpretation | Creative, surprising results |
| 0.3 | Balanced (default) | General purpose |
| 0.7 | Close to description | Specific sound needs |
| 1.0 | Very literal | Exact sound reproduction |

```bash
# Loose interpretation - creative result
belt app run elevenlabs/sound-effects --input '{
  "text": "Magical fairy dust sparkle",
  "prompt_influence": 0.1
}'

# Literal interpretation - precise result
belt app run elevenlabs/sound-effects --input '{
  "text": "Single gunshot, pistol, indoor range",
  "prompt_influence": 0.8
}'
```

## Prompt Tips

**Be specific**: "Heavy rain on metal roof" > "rain sound"

**Include context**: "Footsteps on gravel, slow walking pace" > "footsteps"

**Describe mood**: "Eerie wind howling through abandoned building" > "wind"

**Specify material**: "Glass shattering on concrete floor" > "breaking glass"

## Workflow: Add SFX to Video

```bash
# 1. Generate sound effect
belt app run elevenlabs/sound-effects --input '{
  "text": "Dramatic reveal swoosh with bass drop",
  "duration_seconds": 2
}' > sfx.json

# 2. Merge with video
belt app run infsh/media-merger --input '{
  "media": ["video.mp4", "<sfx-url>"]
}'
```

## Use Cases

- **Video Production**: Transitions, impacts, ambience
- **Game Development**: UI sounds, effects, environments
- **Podcasts**: Stingers, transitions, atmosphere
- **Film/Animation**: Foley, ambience, scoring elements
- **Presentations**: Attention-grabbing sound cues
- **Social Media**: Short-form content audio

contribute

Included

Local-only OSS contribution command center. Auto-refreshes the user's in-flight PR and issue state on invoke so conversations start with full context — no need to brief Claude on what's in flight. Helps the user find issues to contribute to on GitHub, builds per-repo dossiers of what each upstream expects (CLA, DCO, branch convention, AI policy, draft-first, review bots, issue templates), runs deterministic gates before any external action so AI-assisted contributions don't reach maintainers as slop. State is markdown-only: candidate files at ~/.contribute-system/candidates/, repo dossiers at ~/.contribute-system/research/, append-only event log at ~/.contribute-system/log.jsonl. No database, no cloud calls. Use when the user asks about their PRs / issues / contributions, wants to find new work to take on, claim an issue, build/refresh a repo's dossier, or draft a Design Issue or PR. Trigger with "/contribute", "what's my PR status", "find a contribution", "claim issue X", "draft a Design Issue for Y", "refresh dossier for Z".

architectural-analysis

Included

User-triggered deep architectural analysis of a codebase or scoped subtree across eight modes — information architecture, data flow, integration points, UI surfaces, interaction patterns, data model, control flow, and failure modes. This skill should be used when the user asks to "diagram this codebase," "map the architecture," "show the data flow," "give me an ERD," "trace control flow," "find the integration points," "verify the layout pattern," "audit the UX architecture," or any similar request whose primary deliverable is mermaid diagrams plus cited reports under docs/architecture/. Dispatches haiku/sonnet sub-agents in parallel for per-mode exploration, then verifies every citation mechanically before any node lands in a diagram. Not for one-off prose explanations of code (use code-explanation) or for high-level system design from scratch (use system-design).

Designscripts

react-native-skia

Included

Design, build, debug, and optimise high-polish animated graphics in React Native or Expo using @shopify/react-native-skia, Reanimated, and Gesture Handler. Use when the user wants canvas-driven UI, shaders, paths, rich text, image filters, sprite fields, Skottie, video frames, snapshots, web CanvasKit setup, or performance tuning for custom motion-heavy elements such as loaders, hero art, cards, charts, progress indicators, particle systems, or gesture-driven surfaces. Also use when the user asks for fluid, glow, glass, blob, parallax, 60fps/120fps, or GPU-friendly animated effects in React Native, even if they do not explicitly say "Skia". Do not use for ordinary form/layout work with standard views.

plaid

Included

Product Led AI Development — guides founders from idea to launched product.

nextjs-framer-motion-animations

Included

Adds production-safe Motion for React or Framer Motion animations to Next.js apps, including reveal, hover and tap micro-interactions, whileInView, stagger, AnimatePresence, layout and layoutId transitions, reorder, scroll-linked UI, and lightweight route-content transitions. Use when the user asks to add, refactor, or debug Motion or Framer Motion in App Router or Pages Router codebases, especially around server/client boundaries, reduced motion, LazyMotion, bundle size, hydration, or route transitions. Avoid for GSAP-style timelines, WebGL or 3D scenes, heavy scroll storytelling, or CSS-only effects unless Motion is explicitly requested.
