Peak search in a Wav file with time-markers

[Alehins]

I'm doing a scientific project, so my wizard-skills in LabView are quite limited. I need to open a wav file and find signal peaks in it. The closest I could find is this:

The only problem: I need to get not only Frequency and Value, but also the time, when the peak accrued. Any suggestions, how to add this functionality? 

P.S.. I have access to LabView with Signal Processing Toolkit and SignalExpress.

For your problem I think you need to use JTFA. You can read about that here http://zone.ni.com/devzone/cda/tut/p/id/3548

Thanks, Coq Rogue! I added some JTFA functionality for signal visualization. Still, any suggestions about the peak timing measurement?

Alehins,

I found this tutorial that I think will help:

http://zone.ni.com/devzone/cda/tut/p/id/3770 it deals with measuring peaks

and this example goes through just some basic scalar measurements as a reference

Let me know if these work for you. I believe the top link will answer all your questions. Kudos for doing science in LV! 🙂
