Alternatively, Ben has an option here topic22135.html where he has exported PSdata from the Time Domain and imported/viewed in Sonic Visualizer
We also have other export formats that can be used to view data in the frequency domain, these include .wav where you can then view the selected data in 3rd party audio analyzers such as Audacity and again, Sonic Visualizer
Following csv and wav we have AFTX which is a cross platform export format for importing into software suites such as LMS, Head Acoustics and National Instruments
The following link will help viewtopic.php?p=101798#p101798
Could I ask, are the existing frequency display options within NVH missing information that you can only find in other software suites?
If so, could you share what these are and I will add new feature requests for the software team to review
I hope the above helps, thank you again for the post
