ElevenLabs Sound Effects v2 is ElevenLabs' default text-to-sound-effects model. You describe a sound in words and get a matching effect, from footsteps to ambience.

## ElevenLabs Sound Effects v2 prompting tips

- For simple effects, use a clear, short description, such as "Glass shattering on concrete" (ElevenLabs docs: Sound effects).
- For multi-part effects, describe the sequence, such as "Footsteps on gravel, then a metallic door opens" (ElevenLabs docs).
- Do not count on exact repetition counts; ElevenLabs says they are not always followed (ElevenLabs docs).
- Describe the sound itself, close-up or distant, and the surface; Sloosh's node guidance gives "glass shattering on tile, close up".
