    for chunk in audio:
        f.write(chunk)

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"));

Examples with Parameters

# Looping ambient sound, 10 seconds

    duration_seconds=1.0,
    prompt_influence=0.8,
)

Output Formats

Pass output_format as a query parameter (cURL) or SDK parameter:

FormatDescription

pcm_44100Raw uncompressed CD quality
opus_48000_128Opus 48kHz 128kbps — efficient compressed
ulaw_8000μ-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

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
