How to capture desktop audio

Chrome / Edge Best support

  1. Click Start Capture below
  2. In the share dialog, choose what to share (tab, window, or entire screen)
  3. Look for the audio checkbox at the bottom of the dialog — this is the step most people miss!
  4. For a tab: tick "Also share tab audio"
  5. For entire screen: tick "Also share system audio" (Windows/ChromeOS)
  6. Click Share
Share Type Audio Checkbox Label
Browser Tab ✓ Tab audio "Also share tab audio"
Entire Screen ⚠ Buggy in Chrome (may fail) "Also share system audio"
Window ✗ No audio available
Known Chrome bug: Sharing an "Entire Screen" with system audio ticked can fail with "Could not start audio source". This is a Chromium issue, not a problem with this recorder. If it happens, the recorder will automatically retry without audio. For reliable audio, share a browser tab instead — tab audio works every time. Alternatively, enable the Microphone toggle to capture your mic regardless of share type.
