Sound Effects

How It Works

Describe a sound in plain language, and the AI generates it for you. No sound library browsing, no licensing headaches — just type what you need.

Examples:

• "Thunder rolling in the distance"

• "Footsteps on gravel, slow pace"

• "Busy coffee shop with clinking cups and muffled conversation"

• "Car engine starting on a cold morning"

Duration

Sound effects can be 2 to 30 seconds long. Choose a duration that fits your scene.

Prompting Tips

The more specific your description, the better the result.

Good prompts include:

• Environment — Where is the sound happening? Indoors, outdoors, underwater?

• Intensity — Soft, loud, distant, close-up?

• Texture — Sharp, rumbling, metallic, organic?

• Duration cues — Sustained, brief, fading out?

Two Ways to Generate

From Chat

Ask Narra for a standalone sound effect in plain language, such as "generate rain sound" or "create heavy footsteps in a quiet hallway." Narra will prepare a sound-effect clip for you to review and generate.

In Your Script

When the AI writes your script, it automatically includes sound effect cues at the right moments. These are generated alongside your voices and music during audio production.

Standalone (Media Library)

You can also generate sound effects on their own from the Media Library. This is useful when you want to:

• Experiment with different sound descriptions

• Build up a collection of effects before starting a project

• Create effects for use across multiple projects

Save to Library

When you generate a sound effect you love, save it to your Media Library. Saved effects can be reused in any project — just drag them onto the timeline.

Availability

Sound effect generation is available on all plans, with per-plan generation limits. Check your plan details for specifics.
