Where can I find this peak search modul?

[kumpi]

Hi,

I'm a begginer in Labview and I would like to build a program which shows the frequency peaks of a coin sound. This is a part of a bigger project where I want to detect coins by their own sound characteristics. I found a picture which shows something what I want to try, but unfortunately I can't find one of a control part of it. This name is "peak search" on the picture. Could someone help me to solv this?

Thank you!

That subVI doesn't look like one I've ever seen in LabVIEW.  My guess is it is someone's own homemade subVI.

If you search the palettes for "Peak Detector", you can find a built-in LabVIEW subVI you could work with.

The two VIs you attach do not have "Peak Search" in them, and LabVIEW 2019 does not include a "Peak Search" VI.  It does have a Peak Detector VI on the Signal Processing Palette -- is that helpful?

You attached a picture (from where?) showing what appears to be a LabVIEW VI with "Peak Search" on its icon.  What do you know about it?  What version of LabVIEW?  Is it part of LabVIEW, or some third-party software?  Where did you get the picture?  [I generally hate pictures when dealing with LabVIEW, by the way ...].

Thank you for your help! I found the picture in this article. I don't know more details about the program.

Previously I did another program for detect peaks, but unfortunately it can't detect the peaks of the recorded coin sound, just of the sample signal's peaks which was created by me from 3 (5, 15 and 18kHz) signals.

Do you have any idea on how to solve this problem?

Be careful if you want to listen to the sample, it is loud and disturbing!

Thank you!
