ElevenLabs Sound Effects generates a royalty-free sound effect from a written description — footsteps, a door creak, an explosion — for games and video. Call POST /v1/audio/speech with the description in `input`. Options: `duration_seconds` up to 30, `loop: true` for a seamlessly looping bed (rain, wind, machinery), and `prompt_influence` 0–1 for how literally to read the description. Billed per generation, so length costs nothing extra.

--output sfx.mp3→ 用 input 描述音效,duration_seconds ≤ 30;加 loop:true 出无缝循环。按次计费,与时长无关。
