Separation between signals multiplexed at different frequencies. Improper separation can lead to cross talk

See: Separation.

A measure of how well sounds in one channel are isolated from other channels. Low channel separation results in sounds from one channel "leaking" into other channels, a phenomenon called "crosstalk." A classic example is front-channel sounds in Dolby Surround leaking into the surround channels. High channel separation results in more precise placement of sounds.

Degree to which left and right channel signals are separated in a stereo cartridge, FM stereo tuner, Amplifier, etc.

When signals are multiplexed at different frequencies for transmission, then the separation between these frequencies is called channel separation. Poor separation can lead to cross talk.

In a stereo system or its components, a testing standard used to determine the level of freedom from crosstalk between two channels of a stereo system.

A measure of the amount of signal leakage between audio channels, expressed in decibels; higher figures are better.

In audio, a measurement of the amount of leakage between the various channels in a multi-channel installation, specified in dB. While a higher number is better, anything greater than 20 dB (a ratio of 100:1) will be adequate for full stereo separation. See also Cross-Talk.
