# Add Background Music

Background music transforms flat video content into engaging, emotional experiences. The right soundtrack makes tutorials more watchable, product demos more compelling, and social content more shareable. But mixing audio properly — balancing music against dialogue, adding fades, and avoiding copyright strikes — requires both skill and the right tools.

ToolRouter's edit_footage skill layers audio tracks onto your video with intelligent volume management. It balances background music against existing dialogue so the music enhances without overpowering. Add fade-ins, fade-outs, and ducking so music drops during speech and rises during visual-only segments.

This is invaluable for content creators adding production value to their videos, businesses creating branded video content with consistent audio identity, and social media teams who know that videos with music get significantly more engagement.
