ElevenLabs SFX caps at 30 seconds. For ambient backgrounds, environmental loops, and atmospheric layers, you often need longer. Stable Audio 2.5 generates up to 190 seconds of continuous audio from a single prompt. Rain on a rooftop for a three-minute walkthrough. Construction site ambience for a site presentation. Cafe background noise for a restaurant interior showcase.
The model is trained on licensed audio data, which matters for commercial use. The output is not sourced from unlicensed recordings. For studios producing client deliverables, this reduces licensing risk.
Control the output with inference steps and guidance scale parameters. Higher guidance makes the output match your prompt more closely. More steps increase quality at the cost of generation time. For most use cases, the defaults produce excellent results.
190 seconds in one generation
No looping, no stitching, no crossfading. Generate a continuous three-minute ambient track in a single pass. The audio evolves naturally over its duration, avoiding the repetitive patterns that give away looped audio.
Commercially licensed
Trained on licensed audio data. Use the output in client deliverables, published content, and commercial projects without the licensing ambiguity of models trained on scraped data.
