# Audio Post And Delivery

Use this reference when Seedance work involves dialogue, sound design, music, stems, M&E, dubbing, sync, or final delivery checks.

## Prompt-Level Audio

Use prompt audio to direct story timing and mood:

- dialogue: short, quoted, assigned to one speaker;
- ambience: room tone, traffic, rain, crowd bed, machine hum;
- SFX: one or two story-relevant sounds tied to visible action;
- music: broad tempo, energy, instrumentation, or silence;
- sync cue: door slam at endpoint, product click on final frame, light pulse on downbeat.

Avoid exact reproduction claims for protected songs, real voices, or licensed performances unless rights and platform support are clear.

## Post-Level Audio Deliverables

| Deliverable | Purpose |
|---|---|
| Full mix | final stereo/5.1/Atmos or platform-required mix |
| Dialogue stem | spoken lines for edits, dubbing, and cleanup |
| Music stem | music-only layer |
| Effects stem | SFX and designed sound |
| M&E | music and effects without original dialogue for localization |
| Printmaster | approved final master mix |
| Dubbing guide | speaker timing, tone, pronunciation, pauses |
| Loudness report | delivery-target compliance evidence |

## Audio Planning Template

`Dialogue: [speaker/line/language]. Ambience: [bed]. SFX: [visible sync cue]. Music: [tempo/mood or none]. Reference: [Audio1 role]. Post: [stems/M&E/loudness/sync notes].`

## Sync And Loudness Checks

For professional delivery, check:

- lip-sync against final picture;
- music/SFX sync after frame-rate conversion;
- no dialogue masked by music or effects;
- no unintended source-video audio in R2V workflows;
- loudness target and true peak per buyer/platform spec;
- M&E or stems exist if localization is required.

## Common Repairs

| Failure | Repair |
|---|---|
| dialogue desync | shorter line, locked framing, less head motion, one speaker |
| wrong speaker | tag the speaker and split turns |
| music overwhelms line | remove music during dialogue, keep room tone |
| audio reference ignored | map `@Audio1` to tempo or mood and bind a visible event to it |
| video and audio refs conflict | mute video reference or assign video to camera only |
| localization impossible | plan M&E/stems and textless picture before final edit |
