# Set the deck's quiet track.

`POST /pitch-decks/{jobId}/quiet-track`

## Request

- Base URL: `https://docs.sleeperhit.studio/api/v1`
- URL: `https://docs.sleeperhit.studio/api/v1/pitch-decks/{jobId}/quiet-track`
- Auth: HTTP bearer

Sets what the deck's renders with no spoken line are sent as their voice track: `{ quietTrack }` — silence or room_tone, or null to send none again. The field is required (an absent one is refused, 400). The quiet track sends every render of the deck that has no spoken line a voice track with nobody speaking in it (silence, or a soft room tone), the way a spoken render is sent the cast's lines, to test whether quiet faces keep their lips closed when the render hears a track. It is off by default and free, and it changes only the takes rendered after it is set: each take records the track it was sent, and a take already made keeps what it had. A render with a spoken line, and a chapter that keeps its own sound (bells, singers, a crowd), never gets one. A chapter that played its render's own room tone plays the track (silence, or the hush) instead. Free and allowed in any state; nothing is rendered by setting it. Requires `Idempotency-Key`. Scope: `story:write`.

## Headers

- `Idempotency-Key` string, required

## Request body

- QuietTrackSetRequest
  - `quietTrack` 'silence' | 'room_tone', nullable, required: What to send, or null to send none again.

## Response `200`

The quiet track now in force.

A trailer's: The quiet track sends every render of the trailer that has no spoken line a voice track with nobody speaking in it (silence, or a soft room tone), the way a spoken render is sent the cast's lines, to test whether quiet faces keep their lips closed when the render hears a track.
