# ElevenLabs Sound Effects

Generate sound effects from text descriptions — supports looping, custom duration, and prompt adherence control.

> **Setup:** See [Installation Guide](references/installation.md). For JavaScript, use `@elevenlabs/*` packages only.

## Quick Start

### Python

```python
from elevenlabs import ElevenLabs

client = ElevenLabs()

audio = client.text_to_sound_effects.convert(
    text="Thunder rumbling in the distance with light rain",
)

with open("thunder.mp3", "wb") as f:
    for chunk in audio:
        f.write(chunk)
```

### JavaScript

```javascript
import { ElevenLabsClient } from "@elevenlabs/elevenlabs-js";
import { createWriteStream } from "fs";

const client = new ElevenLabsClient();
const audio = await client.textToSoundEffects.convert({
  text: "Thunder rumbling in the distance with light rain",
});
audio.pipe(createWriteStream("thunder.mp3"));
```

### CLI

```bash
elevenlabs text-to-sound-effects convert \
  --text "Thunder rumbling in the distance with light rain" \
  --output thunder.mp3
```

## Parameters

| Parameter | Type | Default | Description |
|-----------|------|---------|-------------|
| `text` | string (required) | — | Description of the desired sound effect |
| `model_id` | string | `eleven_text_to_sound_v2` | Model to use |
| `duration_seconds` | number \| null | null (auto) | Duration 0.5–30s; auto-calculated if null |
| `prompt_influence` | number \| null | 0.3 | How closely to follow the prompt (0–1) |
| `loop` | boolean | false | Generate a seamlessly looping sound (v2 model only) |

## Examples with Parameters

```python
# Looping ambient sound, 10 seconds
audio = client.text_to_sound_effects.convert(
    text="Gentle forest ambiance with birds chirping",
    duration_seconds=10.0,
    prompt_influence=0.5,
    loop=True,
)

# Short UI sound, high prompt adherence
audio = client.text_to_sound_effects.convert(
    text="Soft notification chime",
    duration_seconds=1.0,
    prompt_influence=0.8,
)
```

## Output Formats

Pass `--output-format` (CLI) or `output_format` as an SDK parameter:

| Format | Description |
|--------|-------------|
| `mp3_44100_128` | MP3 44.1kHz 128kbps (default) |
| `pcm_44100` | Raw uncompressed CD quality |
| `opus_48000_128` | Opus 48kHz 128kbps — efficient compressed |
| `ulaw_8000` | μ-law 8kHz — telephony |

Full list: `mp3_22050_32`, `mp3_24000_48`, `mp3_44100_32`, `mp3_44100_64`, `mp3_44100_96`, `mp3_44100_128`, `mp3_44100_192`, `pcm_8000`, `pcm_16000`, `pcm_22050`, `pcm_24000`, `pcm_32000`, `pcm_44100`, `pcm_48000`, `ulaw_8000`, `alaw_8000`, `opus_48000_32`, `opus_48000_64`, `opus_48000_96`, `opus_48000_128`, `opus_48000_192`.

## Prompt Tips

- Be specific: "Heavy rain on a tin roof" > "Rain"
- Combine elements: "Footsteps on gravel with distant traffic"
- Specify style: "Cinematic braam, horror" or "8-bit retro jump sound"
- Mention mood/context: "Eerie wind howling through an abandoned building"

## Error Handling

```python
try:
    audio = client.text_to_sound_effects.convert(text="Explosion")
except Exception as e:
    print(f"API error: {e}")
```

Common errors:
- **401**: Invalid API key
- **422**: Invalid parameters (check duration range, prompt_influence range)
- **429**: Rate limit exceeded
