Some webcams and other digital recording devices come with a built-in microphone. Others rely on a separate microphone to record the audio for your video. If you are having problems recording sound, first locate your microphone. You can do this by creating a test video while you move around the room trying to get closer to or farther from the microphone. Once you have located the microphone, you can adjust its location to change the video’s sound.
If your sound is too loud, you may need to move the microphone away from you, or not speak quite so loudly. If your sound is too quiet, move the microphone closer to you and speak louder. If your microphone is built into your computer, you may want to purchase a separate computer microphone that you can place closer to you to record sound.
