Record tab sound and your voice
- Turn on the microphone
with the 🎙 Mic switch in the Zoomr popup. The first time, Chrome asks for permission.
- Check the level.
In Settings → Microphone & camera you can pick a microphone and watch the level meter move when you speak.
- Start recording
on the tab with Ctrl+Shift+E (on a Mac, ⌘+Shift+E). Any sound that tab plays is captured automatically. There's no separate switch for it.
- Mute when needed
with Alt+Shift+S (Option+Shift+S on a Mac). Zoomr records silence while muted, so the voice stays in sync.
Balance the audio in the editor
Open the Audio tab → Voice & mix. There are separate sliders for your voice, the tab sound and sound effects (clicks, zoom whooshes, typing).
Loudness normalisation is on by default: Zoomr evens the whole video out to −14 LUFS (the level YouTube and Spotify use) with a limiter, so quiet voice-overs aren't drowned out and nothing clips.
Why separate tracks matter
- You can turn down a loud demo video without making your voice quieter.
- Smart Edit can detect when you're speaking and never cut or speed up your voice.
- If you cough, mute (or cut that section) without re-recording.
