Why is there no tab audio in my Sirvez recording?

Tab audio requires the browser tab to be actively producing audio through the Web Audio API during recording.

If the tab is muted at the browser level, if the site's audio permission is blocked, or if the content in the tab is not currently playing sound, there is nothing for Sirvez to capture. Check that the tab is producing audible sound, that tab audio is selected in the Sirvez settings, and that the browser has not blocked the site's audio before starting.
