PlatterSpeed is an easy way to calibrate turntable speed to proper 33 1/3 or 45 RPM using a 3150 Hz testtone.
Using a testrecord with a 3150 Hz track you can record and adjust with your phone from the loudspeaker in an endless loop. The current speed relative to the nominal speed is visualized through a colored graphical indicator.
Measuring the speed this way is absolutely exact in contrast to using a traditional strobe disk. The signal can be recorded and then shown in a graphical chart view (frequency vs. time). Data can be managed in files on to storage. The frequency data can also be evaluated numerically.
*New*: in-app purchase to calculate wow in accordance to DIN IEC 386 (formerly DIN 45507). Expensive special equipment was needed before to do so!
Please note:
* You need a record with the test tone. The Adjust+ testrecord is a perfect fit - others might work as well but no warranty. The app has a demo mode to test its functionality without a test record.
* Refunds are not supported for Google's in-app purchases. Please contact us at platterspeed@adjust-plus.com in case of problems.
* On Honeycomb tablets, there might be problems with correct frequency detection because of echo cancellation. If so, please try to cover the 2nd microphone.
