sound-effects-v2 parameter overview: a short sound effect of a rainy night alley

A real submitted snapshot is used to demonstrate the input structure of ElevenLabs sound-effects-v2: prompt describes the sound effect content (max 450 characters), duration_seconds is the required duration (0.5–22 seconds; automatic duration is not exposed), prompt_influence controls how closely the result follows the prompt (0 is more random, 1 is more literal), and loop controls whether it loops seamlessly. The piece selects the specific soundscape "footsteps in a narrow rainy night alley with distant water sounds," using a relatively short 6-second duration and a moderately high influence to observe how the model organizes ambient layers and point events within a limited duration. It is suitable as a reference for developers who need to add short ambient sounds to short films, game scenes, or UI interactions, covering input phrasing and parameter trade-offs.
