When to use ElevenLabs Sound Effects

Updated 2026-07-31

Where this model earns its cost — and where it doesn't.

This model converts text descriptions into non-speech audio, producing clips between 0.5 and 22 seconds. It handles prompts for environmental sounds, impacts, and mechanical noises. The context window accepts up to 500 tokens for prompt instructions.

On Kyma, the endpoint operates with automatic failover and returns exact usage costs in the response payload. Prompt caching is supported, billing repeated prompt prefixes at 10% of the standard input rate. The model runs on a fast, cheap tier and does not support reasoning, vision, or structured JSON outputs.

Output is strictly audio. The model does not generate speech or music, and it will not return structured data formats. It is optimized for quick generation of isolated sound assets rather than long-form audio composition.

Game Foley Generation

Create impact sounds, footsteps, and environmental cues for interactive media.

Video Post Production

Add background ambience, weather effects, and mechanical noises to video timelines.

UI Interaction Sounds
