To record your screen with computer (system) audio in Sendspark’s Chrome Extension or web app, start the app, select Screen Only or Cam + Screen, hit RECORD, then turn the audio toggle on in Chrome’s share window. Which toggle you see depends on the pane you pick rather than on your operating system: Chrome Tab offers “Also share tab audio”, and Entire Screen offers “Also share system audio”. Both work on Mac and on Windows. The Desktop App captures system audio with no toggle at all.

​
Key takeaways

  • The audio toggle is named after the pane you choose, not your operating system. Chrome Tab gives you “Also share tab audio”; Entire Screen gives you “Also share system audio”.
  • Both panes capture computer audio on Mac and Windows.
  • Choose Entire Screen if the recording needs to follow you between tabs and applications. A Chrome Tab recording stays on the single tab you picked.
  • The Desktop App captures system audio without a per-recording toggle. On Mac, grant it screen recording permission first.
Recording your screen along with the audio of your system can be crucial when sharing certain content. Whether you’re talking over a video, playing an audio file, or interacting with a website, you can record all of it by turning a single toggle on. If you’d rather not think about the toggle at all, use our Desktop App, which records system audio by default. For everything else it can do, see how to use the Sendspark desktop application.

Chrome Extension and web app

If you don’t have the extension yet, install the Chrome Extension here.
  1. Click the Sendspark icon to start the app.
  2. Select Screen Only or Cam + Screen, then hit RECORD.
  3. In Chrome’s share window, pick a pane and turn its audio toggle on.
The share window is Chrome’s own, titled “Choose what to share with Sendspark Video and Screen Recorder”. It has three panes: Chrome Tab, Window, and Entire Screen. The audio toggle sits along the bottom.

​
Chrome Tab

Pick a tab from the list, then turn Also share tab audio on. This captures the audio playing in that one tab. Chrome's share window on the Chrome Tab pane, with the Also share tab audio toggle turned on at the bottom The recording stays with the tab you selected, so it won’t follow you if you switch tabs. If you need to move between tabs or applications mid-recording, use Entire Screen instead. See recording missing when switching Chrome tabs if you’ve already hit this.

​
Entire Screen

Pick a screen, then turn Also share system audio on. This captures everything your computer plays, not just one tab. Chrome's share window on the Entire Screen pane, showing Screen 1 and Screen 2 with the Also share system audio toggle turned on
The Window pane has no audio toggle. If you need computer audio, record a Chrome Tab or your Entire Screen.
To go the other way and record silently, record a video without sound covers turning each audio source off.

​
Desktop App

The Desktop App captures system audio on its own, so there’s no toggle to remember before each recording. Download it for Mac or Windows. On Mac, grant the app screen recording permission before your first recording. If macOS blocks the app from opening at all, that’s a separate setting: see Mac app blocked by Apple security check.
