In Music Production by Hans Weekhout, he says
"People discovered that manipulating instruments was more effective by separating them acoustically. To minimize crosstalk, acoustic screens (gobos) were positioned between instruments. Multitracking became the standard."
I then found in aforum the following comment:
"When separate signals are recorded on two or more channels of magnetic tape, the signal on one channel may be picked up during playback on another channel. This effect is called crosstalk or leakage."
"Because of the close spacing of channels on tape, recorded signals cannot be completely separated during playback (even with the small space between the positions of the channels on tape), and thus some crosstalk is inevitable."
So I thought to myself,
Imagine you wish to record two musicians using multitrack recording. You have Performer A and Performer B with Mic A and Mic B respectively. Now, suppose the performers are standing next to each other and their mics are nearby. Then Mic A will not only pick up Performer A but also Performer B, thus failing to capture their signals separately.
Is this an accurate description of crosstalk? If not, what is crosstalk?
