Place the strobe disc on your record player and start it at the 33 1/3 RPM speed 4. Tap "START" in the True Note app and shine the flashing LED light from your iOS device onto the strobe disc If your record player is playing at the correct speed, you should be able to make out the individual lines on the strobe disc - and they should appear to remain in the same position (not drifting in one direction).
