Add voice, music, and sound

Use narration, music, and sound effects without losing clarity or sync.

Audio gives the timeline its pace. Decide what each layer is responsible for before adding more sound.

Layer	Main job
Voiceover	Carry the explanation or story
Source audio	Preserve speech or sound from existing footage
Music	Set pace, tone, and structure
Sound effects	Reinforce a specific action or transition

Create voiceover

Give the agent the approved script and voice direction:

Generate the approved SCRIPT.md as a warm, direct voiceover.
Natural pace, no announcer energy. Keep the product name pronunciation exact.

The project may keep the spoken text, audio file, and word-level transcript separately so the voice can be regenerated without losing timing work.

Mix for understanding

• Voice should remain clear over music.
• Use sound effects for meaningful events, not every movement.
• Duck music under important speech.
• Avoid cutting words or breaths accidentally at scene boundaries.
• Listen on ordinary headphones and laptop speakers.

Keep timing connected

When narration drives the project, use its real transcript timing rather than estimated scene lengths.

For speech captions, continue to Transcribe and create captions.
