# How to Add Background Music with ChatGPT

ChatGPT approaches audio mixing as a creative conversation, suggesting music moods and mixing strategies based on your content type. Describe the feel you want, preview the mix, and fine-tune volume levels and ducking through natural dialogue. ChatGPT can recommend which sections need music emphasis and which need clean dialogue.

## Setup

{"mcpServers":{"toolrouter":{"command":"npx","args":["-y","toolrouter-mcp"]}}}

## Steps

1. Configure ToolRouter in ChatGPT via MCP settings
2. Share your video and describe the audio: "Add upbeat background music to this tutorial"
3. ChatGPT mixes the audio via ToolRouter
4. Fine-tune: "The music is too loud during the explanation at 1:30 — lower it there"
5. Finalize and export the mixed video

## Example Prompt

```
Add this background music track to my tutorial video. Keep the music soft (30% volume) during speech and raise it (70%) during section transitions. Fade out in the last 5 seconds.
```

## Tips

- ChatGPT can suggest the right music mood and tempo for your content type
- Ask for different music placements to test which version performs better
- Request both a music version and a clean version for different uses
