How to record computer and microphone sound separately

  • If you are a video specialist, you may need to edit the sound of the computer and the microphone separately.
  • In such a case, if you uncheck the "Two Sound Mixing" option, a video with two audio tracks will be created.

  • Since Windows Media Player or YouTube does not support a video with two audio tracks, you will only hear one audio track of the computer sounds or the microphone sound.
  • If you use VLC Media Player, you must select a specific audio track to hear the computer sounds or the microphone sound.
