Flux 3 Audio Model
Flux 3 Audio is a preview layer matched to a generated scene — not a standalone audio generator.

The ambience preview needs a real render. This is the Flux 3 text-to-image generator, free and anonymous.

Capabilities
What the Flux 3 Audio preview is for
Flux 3 Audio sits in the same category as Flux 3 Video: a preview step applied to something Flux 3 already rendered, never a first step of its own. It reads a still you generated and previews the ambience that scene implies — room tone for an interior, weather for a landscape, traffic for a street. It is there to make a moodboard feel closer to finished, not to replace a sound library.
Everything real on this page happens in the Flux 3 text-to-image generator below. Render a scene there and the audio preview has something to sit under. No audio model is called at any point.
Completing a moodboard:
a still plus implied ambience communicates a scene far faster than the still on its own.
Checking scene consistency:
if you cannot say what a Flux 3 render should sound like, the scene is usually underspecified visually too.
Pitching an idea quickly:
the preview is enough to carry an idea in a review without commissioning any sound work.
Being explicit about the limit:
nothing is synthesised, no audio model is queued, and no request leaves your browser for one.

Flux 3 Audio FAQ
No. Flux 3 Audio on this site is an ambience preview matched to a still that Flux 3 rendered. No audio model runs and no request is sent to one.
Because a scene reads differently when you consider how it would sound, and that pass often improves the visual prompt. It is a thinking aid attached to the real image generator, clearly labelled as a preview.
Yes, along with the Flux 3 image generation it depends on. No account, no email and no credits at any point in the flow.
Use Flux 3 for the visual and a dedicated sound library or audio model for the track. Flux 3 gives you the frame; it does not pretend to give you the mix.
