Frequently Asked Questions
It's a tool that uses AI to analyze video content and automatically generate matching ambient audio — sounds like traffic, nature, room tone, or crowd noise that match what's happening in your video.
Yes. Modern AI can generate surprisingly realistic ambient audio by analyzing visual cues in your video — the environment, lighting, movement, and objects on screen.
Ambient sound is environmental audio (traffic, wind, footsteps, room tone) that makes a scene feel real. Background music is a separate musical track. This tool generates ambient sound, not music.
Yes. You own full rights to all audio generated with Dobidy. Use it in commercial videos, social media content, client work, or anywhere else.
