RPM Speed & Wow App-Analysen für 9. September

RPM Speed & Wow requires your smartphone to have the gyroscope sensor. It lets you either look at the speed of your turntable, or measure the average speed, min/max variations and wow value. Put your phone on the turntable the nearer to the center as possible, and you can: - start the turntable and look at the rotational speed of it; - click "start" on the app and start the turntable: the app waits 10 seconds in order to have a steady speed, then acquires data for other 10 seconds and displays average, max-min RPM values and wow estimation. While still spinning, the app becomes red where the turntable runs faster than the average, and blue where the turntable runs slower. The feature is active until the phone is lifted up from the platter. Offset correction: if you do a measure with the phone flat and steady, the mean rpm value will be automatically set as an offset for the next measurements. Offset correction remains active until the app is closed and reloaded. Active Offset-correction is indicated by a text message. Tap "reset" to reset the app to do another measurement (this does not reset the offset of the current session). Tap on the speed number to re-align it. After a measurements is completed, tap "Save" to store the data for future review. Tap "Hystory" to review saved data. Please pay attention that if the app is unistalled the saved data are deleted. RPM S & W requires that your phone has a gyroscope. Uses jjoe64 Graphview library. Enjoy vinyl listening!
