Gain an acoustic impression of a sound event by listening to the sensor signal in real-time. Benefit from the superior advantages of the Microflown particle velocity sensor, in terms of background noise cancellation and signal-to-noise boost, for locating sound sources. This allows using it directly at the test location in presence of environmental sounds also for non-stationary sources such as buzz, squeak & rattle. Real time filters on the audio supports to run more targeted analysis. A variety of options for real-time filtering on all channels combining: low pass, band-pass , band-stop and high pass filters.
