# AI Sound Effect

Sound design can make the difference between a flat clip and one that stops the scroll. AI Sound Effects watches your video, detects key moments, and places production-quality sound effects on your timeline automatically — no editing experience needed.

## How to use AI Sound Effects

1. From the homepage, click **AI Sound Effect** in the Quick Start. You can also access it from the editor: open a clip and click **Audio** in the right sidebar.

</div>

2. In the **Audio** panel, click the **AI sound effects** tab. Then click **Auto generate sounds** — OpusClip analyzes your video and adds SFX automatically. This takes under 2 minutes for a 60-second clip.

</div>

3. Your sound effects appear as colored blocks on the timeline. Click any block to adjust its **Volume**, **Duration**, or edit the **Prompt** and regenerate that specific sound.

## Generate a sound by prompt

1. On the **AI sound effects** tab, click **Generate by prompt**.

</div>

2. Describe the sound effect you want in the **Prompt** field (e.g., "funny sound effect" or "deep cinematic boom"), set the **Duration**, then click **Generate 3 versions** and pick the one that fits best.
