Shaknspin

Analyseur de vitesse / Turntable Speed Analyser

Measure

Using a sophisticated 9 degrees-of-freedom sensor, Shaknspin can accurately measure the rotational speed of your turntable platter, 500 times per second.

The new version 2 improves on that by always performing an automatic calibration at the start of each measuring session. The calibration uses a fast reacting IR sensor and a marker to make sure that 33.33 is indeed 33.33

You can see the whole calibration process here.

  • Shaknspin. Prix : 260,00€

  • The Speed option allows the platter speed to be continuously displayed allowing you to confirm that all is well.

  • Analyze: Wow&Flutter analysis is another method of operation. Following a brief measuring period, the following indicators are calculated and displayed:
    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&F peak-to-peak 2sigma / Wow / Flutter / W&F (DIN weighted) / Modulation frequency (primary) / Modulation frequency (secondary) / Jitter (average speed change / second)

  • This is very valuable information, allowing you to see the characteristics of the platter rotation in terms of speed stability and giving clues to where any issues might be.

  • Graphical representations of the speed variation, flutter component and calculated average are also available.

  • But there’s more… A spectrogram of the modulating frequencies and an histogram for the speed variation are also immediately available.

  • Connect. At the end of each measuring session, you can optionally choose to download the collected data into your smartphone (Android or iPhone), for additional analysis and / or archiving – See links for download at the bottom of the page.
    The built-in Bluetooth connection allows this quick and easy transfer of data.

  • The common CSV file format generated by our app, allows the data to be easily read into Excel and analyzed or graphed with the supplied template.

  • Share. After generating the CSV file, you can submit it to our growing database of turntable performance characteristics. Just email it to us at shaknspin@sempersonus.com and we will add it ourselves.
    At anytime, you can check the current database by downloading the spreadsheet here.
