Audio Sound Effects
Sound effects are paused. As of 2026-09-12 no SFX model is being served — no customer jobs in the preceding 30 days. The endpoint still exists; a request returns 404 model_not_found. Nothing was deleted. This page is no longer in the docs navigation; it records how the endpoint behaves.
Synchronous endpoint. Describe a sound — door slam, rain, sword unsheathing, ambient room — get back a clip. Music generation is paused too.

Request

application/json body.
string
default:"elevenlabs-sfx"
SFX model. Currently only elevenlabs-sfx is shipped.
string
required
Description of the sound. Max 500 characters. Also accepts text as an alias.
number
Optional duration 0.5 to 22 seconds. Omit to let the model auto-pick a sensible length.
number
default:"0.3"
How literal the prompt should be (0 = creative, 1 = strict). Range 0–1.
string
default:"mp3_44100_128"
Audio format. Same options as audio/speech.

Response

200 OK with audio bytes. Flat pricing — duration doesn’t change the cost.
