Sound and Vibration kit - Peak Hold

[mstocker]

I am evaluating a dynamic signal and would like to gather peak hold information from SVT 1/3 octave output. The SVT FFT tool has a "peak hold" function that allows for gathering spectral data over time, but it does not output an array of values. Is there a way I can capture peak hold from the SVT 1/3 octave output and create an indexed array that integrates a dynamic signal in a "peak hold" manner?

I am evaluating exposure impacts of anthropogenic noise on marine animals for ocean noise pollution mitigation.

Thanks!

Hello mstocker,

From your post this is what I understand:

You want to perform peak hold averaging with your Third-Octave Analysis.vi and then obtain an array of data of  the peak values. The Third-Octave Analysis.vi has a selection for the averaging type you can select peak averaging as the type of averaging. Peak averaging combines the results of several measurements into one final measurement. The output of the Third-Octave Analysis.vi is a cluster. The cluster contains one array of nominal frequencies and an array of band power. Is this what you were looking for?

If I have misunderstood your post, please reply with clarification. I would really appreciate it.
