System audio
Capture every sound your computer makes - alongside your microphone, with no echo, no double-tracking.
Pro feature. System audio is one of the unlocks on Pro and the Peak Productivity bundle.
How to enable it
- Open the extension popup.
- Toggle System Audio under the Audio section.
- Start recording.
On Tab mode, system audio is captured directly via Chrome's tabCapture API - perfect, no permission prompt, no extra dialog.
On Screen or Area mode, Chrome's screen-share dialog includes a "Share audio" checkbox. Tick it and the OS routes system audio into the recording.
Microphone + system audio together
Mix both. Screen Recorder Pro applies echo cancellation and noise suppression to the mic track by default, so you don't get the awful loop where your voice plays back into itself through the system audio.
Adjust mic gain in Settings -> Audio if your voice sounds too quiet relative to the system audio.
What about DRM-protected content?
Netflix, Spotify, Apple Music, and other DRM-protected sources may produce silent recordings - that's a platform-level restriction, not a bug. Recordings of your own apps, YouTube, web meetings, etc. all work fine.
System audio on macOS
macOS doesn't expose system audio to Chrome's "Share audio" toggle for full-screen mode the way Windows and Linux do. Tab mode is your friend on macOS - tabCapture audio works perfectly. For desktop apps, install a virtual audio driver (BlackHole, Loopback) and route it to a mic input.
