The Portuguese manufacturers say that Shaknspin is “probably the first small, affordable, fully contained Wow&Flutter analyser for turntables”.

Shaknspin has a 500Hz sampling rate and several analysis modes, it can show you the weaknesses and strong points of any turntable drive system characteristics. All source and calculated data is then available for download into a spreadsheet, allowing you to further understand the data and even share it with others, enabling the creation of turntable performance databases.

Shaknspin Wow&Flutter Analyser For Turntables

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.
