Stop band attenuation (dB) - Is the degree to which the frequency spectrum is attenuated (outside audio band).

Channel Separation (dB) - Also known as Cross-Talk. This is a measure of the amount one channel is isolated from

the other. Normally measured by sending a full scale signal down one channel and measuring the other.

Pass-Band Ripple - Any variation of the frequency response in the pass-band region.
