Working with Audio

Audio is a huge part of what makes a video feel polished and professional. StarZero Agents gives you flexible control over the audio in your projects, whether you're working with the sound that came with your video clips or layering in additional tracks like music and narration.

Two Types of Audio

There are two kinds of audio you'll work with in StarZero Agents:

Clip audio is the original sound that's part of each video clip — dialogue, ambient noise, whatever was recorded with the footage. Every video clip in your project has its own audio, and you can turn it on or off individually.

Separate audio clips are additional audio tracks you add on top of your video. These could be background music, voiceover narration, sound effects, or any other audio you want to layer in. You can source these from your library, extract them from URLs, or generate them with AI — including narration, music, and sound effects. Audio clips sit on their own track below the video and can be placed anywhere on the timeline.

Layering and Mixing

Audio clips can overlap each other and play at the same time as your video clip audio. This means you can have dialogue from your video playing while background music hums underneath — just like a real production.

You have volume control on every clip, so you can balance everything to sound just right. Turn up the narration, bring the music down, mute a clip that has unwanted noise — it's all up to you.

What You Can Do

Here's a quick overview of what's possible with audio in StarZero Agents:

• Enable or disable the audio on any video clip
• Add separate audio clips from your library content
• Extract audio from URLs like SoundCloud or YouTube links
• Generate narration using text-to-speech AI voices
• Separate vocals from background using AI-powered speech separation
• Generate music — create original background music from a text description
• Generate sound effects — create custom sound effects from a description
• Adjust volume on any clip from silent to double volume
• Position audio anywhere on the timeline with precise start times
• Trim audio by setting in and out points to use just a portion
• Download audio — each audio result shown in the chat has a download button so you can save it directly to your device
