In this video tutorial, viewers learn how to record audio, using Camtasia Studio 6. Camtasia Studio is a screen video capture program. The user defines the area of the screen or the window that is to be captured before recording begins; it is also possible to capture the entire screen area. You can also talk, and use a videocam. Begin by selecting the Camtasia Studio icon in the taskbar. Right-click it and select the sound option. When the window pops up, enable all the options to be able to see stereo-mix and click OK. Now users can record sound that comes out of their stereo. This video will benefit those viewers who make voice narration videos and would like to learn how to record the audio.
