You guys might want to try an app called Turntabulator. It does give the correct baseline speed of 33.33%. And has a 0.1% resolution for wow n flutter.
Both my TT’s come out as 33.33% exact. (Within the 0.1% resolution).
Use the “exact” mode on the settings menu.
I would worry if a TT does show a variation of 0.1% or more. In my case it shows 0.0% slow or “exact”.
I tried it. Reads 33.33 exactly unless I mess with pitch or something.
I played around some more with RPM Pro. I did a manual recalibrate on it and calculated the “fudge factor” value to get it to read 33.33 accurately (it’s like 0.989 or something like that). So it can be forced to display the correct speed. It’s a mystery to me why it would need special calibration for something so basic.
However RPM Pro’s wow & flutter number still varies between 0.16% and 0.25%, depending on where and how I place the phone on the platter. I don’t trust that number at all.
