EVEN stranger, even if one is passing a beam of light, one will still measure the same speed, even if going at say 99% the speed of light.the wow and flutter measurements. Fig. 5 Spectrum and unweighted peak wow & flutter of a 3150 kHz signal from a turntable In Multi-Instrument, to measure the wow and flutter, set the Oscilloscope frame width (a.k.a. record length or sweep time) to be at least 5 seconds (10~60 seconds is recommended).

Techs usually tend to do multiple runs (15 to 20) to arrive at a weighted average of the wow and flutter WTD RMS measured with a reference tape containing 3150 hz tone .. The reason I ask is that the .067% WOW and Flutter is slightly more than the published specs of 0.04% for a classic transport..Is this because of only one run.. Wow and Flutter Perceptual Model As I noted, my goal is not to convince you of audible artifacts of Wow and Flutter. But let me share some data that I do have since the topic has been so much discussed by Arny. The first point is that when we perform Wow and Flutter measurements, we use a standardized frequency weighting.
