Line in
Alternatively
referred to as audio in and sound in, the line in or line-in is a port found on computer sound cards that enables a user to connect an external audio device such as a cassette tape player, disc player, audio mixer, additional microphones, etc. to record or otherwise manipulate the incoming audio.
In the picture to the right, is an example of the back of the sound card. With
this sound card the line-in port is blue and is represented as an arrow
pointing into sound waves.
