ShaknSpin Turntable Analyser MKII
Using a sophisticated 9 degrees-of-freedom sensor, Shaknspin can accurately measure the rotational speed of your turntable platter, 500 times per second. The Speed option allows the platter speed to be instantly displayed allowing you to confirm that all is well. However, Wow & Flutter analysis is the main purpose. Following an 8 seconds measuring period, the following indicators are calculated and displayed (some only available from the phone app):
Average speed in RPM
Average speed deviation
Max / min speed variation
Max% / min% speed variation
High pass filtered max / min speed variation
W&F DIN
W&F WRMS
W&F peak-to-peak
W&P peak-to-peak 2-sigma
Wow
Flutter
Modulation frequency (primary)
Modulation frequency (secondary)
Jitter (average speed change / second)
The data can be stored remotely and an app is available to use with your smartphone.
