Stable Audio 3 Small SFX AI sound generator
Design high-fidelity sound effects and ambient room tones with Stable Audio 3 Small SFX. Create immersive cinematic audio for your video projects.
Best for
Stable Audio 3 Small SFX is the ambience generator on the Framings sound-effects screen. Use it for weather, rooms, crowds at a distance, and other beds that need to sit under a picture. Clips run up to 10 seconds or up to 30 seconds, as MP3 or WAV.
Controls and pricing
Describe the space more than the plot. Rain on a roof with no voices, or a museum with one set of footsteps, stays coherent. If you need a sharp one-shot under 22 seconds, ElevenLabs SFX is the other model on this screen and uses a different credit price.
How to use it
Open sound effects, choose Stable Audio 3 Small SFX, pick the length and the format, and generate. The table shows 10 and 30 seconds on the Free plan. A very short cue still has a floor, so it does not collapse to a token credit.
Good to know
Stable Audio 3 Small SFX is not a music model. A melody or a vocal belongs on Stable Audio or MiniMax Music. You can lay an Stable Audio 3 Small SFX bed under either of those in the video editor, and each generation keeps its own credit charge.
Where it fits
Thirty seconds is the length to use under a shot that holds. Ten seconds is the length for a transition. Export WAV if you will mix the bed with voice or music, and MP3 if the file is going straight into a quick cut. Name the space, the distance, and what should stay out of the recording.
Prompting tips
Leave voices out of an ambience prompt unless a distant murmur is the point. A clean room tone is easier to mix under dialogue you will add later. Stable Audio 3 Small SFX's 30 second WAV is the file to keep when the edit still has levels to set. Ten seconds is enough when the shot is a cutaway.
