Speed analysis tool plug-in (speedalyzer)

This tool allows versatile analysis of rotating system. The output is a graph that shows the frequency deviation over time with high resolution. This allows to easily identify variations of the speed. You can monitor high speed variations (flutter), low speed variations (wow) and very low speed variations (drifts). Time analysis window can be milliseconds to hours.


  1. Rotating machines analysis: High speed fluctuations might indicate damaged bearings. Monitoring the idle speed of a engine verifies control components
  2. Tape machines wow&flutter analysis. This plug-in measures according to IEC60386 with 3kHz and 3.15kHz
  3. Alerting: WinAudioMLS can monitor the speed and create alert events if adjustable conditions are met.
