Music & Voiceover
Storyline Forge lets you add background music and a voiceover narration to any project. Both are generated by AI from a text description you provide Both are attached to your project from the Projects page, and are not accessed from inside the storyboard workspace.

Generating Background Music
Click the music note icon on your project card to open the Audio Generation modal.
Model: Choose between Lyria 2 (Google — high-quality 30-second audio at 48kHz stereo) and ElevenLabs Music (custom length and format). Lyria 2 is selected by default.
Audio Description: Enter a detailed description of the music you want. Include genre, mood, instrumentation, pacing, and texture. The field accepts up to 500 characters. Vague prompts produce generic results — the more specific you are, the better the output.
Negative Prompt (optional): Describe elements to exclude — for example, "No vocals. No drums. No upbeat elements." Use this to steer the model away from unwanted sounds.
Click Generate Audio. Generation typically takes 30–60 seconds. When complete, a preview player appears. Click Save to Project to attach the track to your project.
