Wan 3.0 audio on Sume: generate_audio and audio references
Wan 3.0 on Sume can make its own audio with generate_audio or take up to 5 audio references. What to send, and how the 30-second price changes (it does not).
Wan 3.0 on Sume has an optional generate_audio flag and accepts up to 5 audio references. Its Sume price is per output second by resolution; compare usage.cost on a first job with audio on and off.
The docs state that the Seedance 2.x models, Wan 3.0 and MiniMax H3 models accept audio references; Omni Flash does not.

Why audio references
An audio reference lets you steer the sound of the output with an existing clip: a voice, a music bed or a room tone. Wan 3.0 on Sume takes up to 5 per job.
Use them to keep a series sonically consistent, for instance one theme across several 15-second episodes.
Costs and limits
Wan 3.0's list rate is per output second by resolution on fal ($0.05, $0.10, $0.20), and Sume bills times 1.25. The catalog does not describe a separate audio fee. Verify on your first job.
The shortest allowed Wan clip is 2 seconds and the longest 30.
