“Weighting” is applied to the measurement to reduce the measurement’s sensitivity to very
low and very high rate of frequency shift. The actual amount of frequency shift is much greater
than the number implies. The weighting network is supposed to create a number related to a
subjective ability to hear wow and flutter.
Reviewers have incorrectly attributed wow and flutter to the turntable. Since the advent
of the belt drive turntable, wow and flutter has been purely a function of tonearm geometry, the
phono cartridge compliance with the elastomeric damping, and surface irregularities in the LP. In
our own lab we have measured many high quality turntables using a rotary function generator
directly connected to the platters of the turntables.
