RPM - Turntable Speed Accuracy

Witness the revolution, improve your sound!

Nothing beats the sound of vinyl records: drop the needle and drift away into a high-fidelity soundscape, just as the artist intended. That is, unless your record player is letting you down.

We take pride in the record collections that we’ve carefully cultivated over years, or even decades. And while the chipmunk voices and warped guitar solos may be subtle, those of us with a good ear will hear it straight away. What a waste.

This is the BEST turntable RPM speed and accuracy testing mobile app available.

See the average rpm of your turntable as well as speed variations (known as wow/flutter) in real-time graphics designed to help you find and fix errors in your setup. You won’t find an easier way to track the wow/flutter effects than the intuitive graphs presented by RPM anywhere on the market.

RPM is proud to be recommended by Rega Research Ltd, makers of some of the best turntables in world.
Great review by top tech blogger Techmoan on Youtube.
This app is even used in high end Turntable reviews in Stereophile magazine.

So how does it work?

RPM uses the gyroscope in your iPhone to determine the rotation speed of your turntable, automatically determines which speed setting you’re on, and reports how accurate it is.

Simply place your iPhone flat over the centre of the turntable platter. As the iPhone rotates the display will remain stationary from your perspective for easy reading.

The UNIQUE feature of RPM is that it shows a scrolling graph of rpm accuracy variation over time, this shows wow/flutter effects, especially those associated with the turntable not being level, belt wear or other mechanical imperfections. You can even detect the small drag caused by the stylus resting in the grooves.

And to add to all of that, you can even visualise wow and flutter variations plotted actually around the vinyl centre to show a heat map of exactly where in the turntable rotation the inaccuracies occur.
