ElevenLabsTextToSoundEffects - ComfyUI Built-in Node Documentation - ComfyUI

The ElevenLabs Text to Sound Effects node generates audio sound effects from a text description. It uses the ElevenLabs API to create sound effects based on your prompt, allowing you to control the duration, looping behavior, and how closely the sound follows the text.
