From Wikipedia, the free encyclopedia
Crosstalk measurement is made on audio systems to
determine the amount of signal leaking across from one channel
to another.
Interchannel crosstalk applies between the two channels of a
stereo system, and is usually not very important on modern
systems, though it was hard to keep below the desired figure of
-30dB or so on
vinyl recordings and
FM radio.
Crosstalk between channels in mixing consoles, and between
studio feeds is much more of a problem, as these are likely to
be carrying very different programmes or material.
The
IBA drew up a weighting curve for use in crosstalk
measurement that gives due emphasis to the subjective audibility
of different frequencies, as shown here. This is still in use,
despite the demise of the IBA, and in the absence of any
international standards is worth adopting.
