( For narrative shows )

Score the story, not just the intro

A narrative episode is chapters, and chapters want music that changes with them. In Cast the structure lives in the transcript — mark the beats where the story turns — and the music is generated per section, in parts, ducking under the narration on its own.

Produced is a texture, and it is buildable

What separates a produced narrative show from a read-aloud essay is texture: a bed that enters when the scene changes, a sting on the reveal, silence used on purpose. Cast generates each of those pieces to order — a looping bed, an intro/outro, a short sting — and sound effects described in a sentence.

The mechanics stay out of the way: chapters mark the structure, the duck follows the narration through every re-edit, and stems keep each layer separately adjustable to the end.

  • Chapters as story beats
  • Beds, stings and SFX to order
  • Ducking survives re-edits
  • Every layer stays separate

FAQ

01How do I add chapters with timestamps?

Select the text where a chapter should start and mark it (⌘⇧M) — the title comes from your selection. Chapters export as timestamp lists for YouTube and for Podcasting 2.0.

02How do I generate music for a section?

Describe what you want, pick what kind of track it is — a background bed that loops, an intro/outro, or a short sting — and Cast generates an original track for the episode. It is generated for you, not pulled from a catalogue other shows are also using.

03How do I add sound effects?

Describe the sound and Cast generates it — a whoosh, a transition, an ambience. Ask for up to four variants in one run and keep the best.

04Why does the music duck under the narration?

That is auto-ducking. The music drops under the voice and comes back in the gaps, automatically — and because the duck follows your actual voice clips, it stays correct after you cut. Trim a minute of filler and the music re-balances itself. You never draw a volume envelope by hand. You can set how far it drops, or switch it off.
