Special Sound Device and Sound Source.

	if you want to record RealPlay, Windows Media Play or other application's sound , you can special the sound source as Stereo Mix ( usually named Wave, Stereo Mix, What You Hear, or something in similar wording)
	if you want to record microphone, you can special the sound source as Microphone or Mic.
	Connect the Line-Out output on an external sound system or PA to the Line-In or Aux input on the computer and record from the Line-In, Aux or Auxiliary sound source. This is of course most appropriate with complex performances where some sort of sound system is already in place, such as in theaters or concert halls.
