Measuring turntable speed

As an aside, is turntable speed all that important. I think not as important as speed variations like wow and flutter. The absolute speed could be off 1 or 2% and most of us myself included would not know.

For once we agree on something!

How many here are going to claim they can hear the difference between 33.30 and 33.40 say as long as speed is constant?

I know I cannot......

Have a great day!

I guess one question is how accurate you are looking to get as yes an Android phone app is not going to be the last word in accuracy.
But if all you are looking for is to get very close and check stability they are free and fairly decent.

PS. That does NOT mean I am not going to strive for 33.33 but just saying.....

Great programs but I think the one called RPM Speed and Wow on Android has the edge.
I checked that one against my industrial strobe and it was surprisingly accurate.
Average of 33.39.

I am impressed with it.

I have an industrial rpm/ fpm etc etc strobe that I use for work.
It has two modes, contact with various size wheels and strobe non contact very similar to the one Greg linked to.
It is EXTREMELY accurate.
But for a test I also just ordered one of them at $15 so I can compare to my industrial unit.
Will report back.
