Integrated Audio Synthesis
Both Seedance 2.0 and Seedance 2.5 synthesize synchronized environmental audio and action sound effects directly alongside video frames.
Default Audio Rule: No BGM, Just SFX
By default, DigitalXLR configures video prompts with the directive:
Audio: No BGM, just SFX.This prevents unwanted background music tracks from interfering with your production, allowing sound effects (foley, footsteps, rain, engines, sword clashes) to remain clean for post-production editing.
Prompting for Action Sound Effects
You can guide sound effect generation inside your prompt's audio section:
[Audio] Heavy rain patter on asphalt, distant thunder claps, metallic footsteps echoing, no BGM.Note: If you plan to add custom background music in your video editor, clean SFX-only audio ensures seamless audio mixing.
