Description

The most detailed Turntable Wow & Flutter display and analysis available on an iPhone.

If you want the best listening experience from your turntable then its speed variation, the Wow & Flutter, is more of a problem than a low or fast RPM.

If your turntable speed is 33 or even 34, instead of 33 1/3 most people will not notice, yes the absolute pitch is slightly off but this is mostly unnoticeable.

If you have bad wow & flutter then everyone will notice!

"Wow Flutter" will give you the best detailed graphical view of your turntables speed variation per revolution available from an iPhone.

The turntable average RPM and the final Wow&Flutter are also displayed for reference.

Wow & Flutter is caused by many factors, platter imbalance, platter not level, drive belt imperfections, and drive motor vibrations. "Wow Flutter" will help you identify which of these it could be and let you see the improvements you make. The vertical lines indicating each revolution help indicate a periodic repeating pattern which is likely linked to the platter, versus a random variation which more likely a belt or motor issue.

Needs better instructions

The only instruction is “place over center of platter”. The center of the platter has the spindle sticking straight up. So do I place the phone so is balanced in the spindle? This seems hard to do so maybe you just leave it leaning on the spindle. Maybe I’m supposed to place it flat on the upper or lower have of the platter? But how close? Should the side of my phone be touching the spindle? But that’s not the “center of the platter”? Seems like 1 more sentence or a picture could have cleared this up.

Hi, thanks for your constructive feedback. I always place a circular tape holder over the spindle and place the phone centred on top of that.
I will look at improving the instructions.
