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