# Generate a sound effect
audio = client.text_to_sound_effects.convert(
    text="thunder crashing in the distance",
    duration_seconds=3.0
)

# Save to file
with open("thunder.mp3", "wb") as f:
    for chunk in audio:
        f.write(chunk)

Basic Usage

Generate a Sound Effect

from elevenlabs import ElevenLabs

client = ElevenLabs(api_key="YOUR_API_KEY")

audio = client.text_to_sound_effects.convert(
    text="waves crashing on a beach",
    duration_seconds=5.0
)

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

Create Looping Sound Effects

# Generate a seamlessly looping sound
audio = client.text_to_sound_effects.convert(
    text="gentle rain falling",
    duration_seconds=10.0,
    loop=True  # Optimized for seamless looping
)

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

Parameters

Text Description

The text parameter accepts natural language descriptions of the sound you want to create:

# Environmental sounds
client.text_to_sound_effects.convert(text="wind howling through trees")

# Mechanical sounds
client.text_to_sound_effects.convert(text="old door creaking open")

# Nature sounds
client.text_to_sound_effects.convert(text="birds chirping in the morning")

# Urban sounds
client.text_to_sound_effects.convert(text="city traffic ambience")

Duration Control

# Short sound effect (1 second)
audio = client.text_to_sound_effects.convert(
    text="door knock",
    duration_seconds=1.0
)

# Medium sound effect (5 seconds)
audio = client.text_to_sound_effects.convert(
    text="rain ambience",
    duration_seconds=5.0
)

# Long ambient sound (30 seconds)
audio = client.text_to_sound_effects.convert(
    text="ocean waves",
    duration_seconds=30.0
)

Prompt Influence

Control how closely the generation follows your text description:

# High influence - very literal interpretation
audio = client.text_to_sound_effects.convert(
    text="glass breaking",
    prompt_influence=0.9
)

# Medium influence - balanced
audio = client.text_to_sound_effects.convert(
    text="footsteps on gravel",
    prompt_influence=0.5
)

# Low influence - more creative interpretation
audio = client.text_to_sound_effects.convert(
    text="mysterious atmosphere",
    prompt_influence=0.2
)

Output Formats

# MP3 format (default)
audio = client.text_to_sound_effects.convert(
    text="thunder",
    output_format="mp3_22050_32"
)

# High-quality MP3
audio = client.text_to_sound_effects.convert(
    text="thunder",
    output_format="mp3_44100_192"  # Requires Creator tier or above
)

# PCM format for editing
audio = client.text_to_sound_effects.convert(
    text="thunder",
    output_format="pcm_44100"  # Requires Pro tier or above
)

Async Usage

from elevenlabs import AsyncElevenLabs
import asyncio

async def generate_sound_effect():
    client = AsyncElevenLabs(api_key="YOUR_API_KEY")
    
    audio = await client.text_to_sound_effects.convert(
        text="explosion in the distance",
        duration_seconds=3.0
    )
    
    chunks = []
    async for chunk in audio:
        chunks.append(chunk)
    
    return b"".join(chunks)

audio_data = asyncio.run(generate_sound_effect())

Batch Generation

Generate multiple sound effects efficiently:

from elevenlabs import AsyncElevenLabs
import asyncio

async def generate_multiple_effects():
    client = AsyncElevenLabs(api_key="YOUR_API_KEY")
    
    sound_descriptions = [
        "thunder",
        "rain",
        "wind",
        "fire crackling"
    ]
    
    tasks = [
        client.text_to_sound_effects.convert(
            text=desc,
            duration_seconds=5.0
        )
        for desc in sound_descriptions
    ]
    
    results = await asyncio.gather(*tasks)
    
    # Save each sound effect
    for i, (desc, audio) in enumerate(zip(sound_descriptions, results)):
        chunks = []
        async for chunk in audio:
            chunks.append(chunk)
        
        with open(f"{desc.replace(' ', '_')}.mp3", "wb") as f:
            f.write(b"".join(chunks))

asyncio.run(generate_multiple_effects())

Use Cases

Video Production

# Generate ambient background sounds
ambient = client.text_to_sound_effects.convert(
    text="busy coffee shop atmosphere",
    duration_seconds=30.0,
    loop=True
)

# Generate specific action sounds
action = client.text_to_sound_effects.convert(
    text="car door slam",
    duration_seconds=2.0
)

Game Development

# Background ambience
forest_ambience = client.text_to_sound_effects.convert(
    text="forest with birds and insects",
    duration_seconds=60.0,
    loop=True
)

# Interactive sounds
footsteps = client.text_to_sound_effects.convert(
    text="footsteps on wooden floor",
    duration_seconds=1.0
)

Podcast Production

# Intro/outro sounds
intro = client.text_to_sound_effects.convert(
    text="upbeat notification sound",
    duration_seconds=2.0
)

# Transition effects
transition = client.text_to_sound_effects.convert(
    text="swoosh transition",
    duration_seconds=1.0
)

Best Practices

Writing Effective Descriptions

• Be specific about the sound you want
• Include details about intensity, distance, and environment
• Use descriptive adjectives (“loud”, “gentle”, “distant”)
• Mention specific objects or actions (“glass shattering”, “metal clanging”)

Duration Guidelines

• Short effects (0.5-2s): Impacts, hits, notifications
• Medium effects (3-10s): Transitions, specific actions
• Long effects (15-60s): Ambient backgrounds, atmospheres
• Use looping for continuous backgrounds

Format Selection

• MP3 22050Hz: Good for web, small file size
• MP3 44100Hz: Better quality, larger files
• PCM: Best for editing and post-processing
• WAV: Lossless quality for professional use

Limitations

• Maximum duration may vary based on your subscription tier
• High-quality formats (192kbps MP3, PCM, WAV) require higher subscription tiers
• Generation time increases with duration
