Mainly tells you the hole is off-center on the disc.
Please explain to me the fascination with vinyl because I don't get it.
The review says something about a small disc and reflective tape. I don't know how any of that works, but I assume the reflective tape only gives you one measurement per revolution.
...it's not something I ever worried about. I don't think I've ever heard flutter from a turntable...
You are aware that a plain old strobe disc with a neon lamp or old style magnetic ballast fluorescent light will cost less and be more accurate than the digistrobo gadget.
Unless something is totally messed up, 'wow' on a turntable is a 'once-around' of the platter and is usually a manufacturing defect of the disc -- the hole is off center.
This thing is utterly useless for wow&flutter... The PF review was written by someone who doesn't understand w&f.
If you are interested in w&f then you could use a test record with a known reference tone, record it, demod it, plot spectrum.
I publish the W&F reference tone from the Ultimate Analogue Test LP right here on HA for every turntable I review. Even for the worst, ceramic cartridge USB turntables.The problem is I don't have the software or know-how to extract a figure from it.Thanks for chiming in. It looks like this type of instrument will really only serve as a way to measure speed. That is my primary goal anyway.
Axon mentioned a tool he developed in his Blog. Have you tried it, or are we still waiting on him to publish it?
