I hear an echo when recording my mic and tab/system audio

Recording both your microphone and tab/system audio in the same recording can cause an echo if you're not wearing headphones.

This happens when the tab/system audio is played loudly through your speakers and is then picked up again by your microphone (hence the echo effect).

To avoid an echo, we recommend doing one or both of the following:

  1. Wearing headphones when recording both microphone and tab/system audio
  2. Muting the tab/system audio on your computer's speakers (Screencastify will still detect and include the audio)
