ElevenLabs Sound Effects
Generate sound effects from text descriptions — supports looping, custom duration, and prompt adherence control.
Setup: See Installation Guide. For JavaScript, use
@elevenlabs/*packages only.
Quick Start
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
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"));
cURL
curl -X POST "https://api.elevenlabs.io/v1/sound-generation" \
-H "xi-api-key: $ELEVENLABS_API_KEY" -H "Content-Type: application/json" \
-d '{"text": "Thunder rumbling in the distance with light rain"}' \
--output thunder.mp3
