How to use cursor to subset data from an acquired sound graph...

[labproffessor]

I have attached the file below. When I simulate a signal it works perfectly, but if I switch out the simulated signal for acquired sound, i doesn't seem to be able to subset the data between the cursors.

If you save back to 17 (or 14), more people will be able to help you.

Hi professor,

always select the cursor first, then read the properties of that cursor!

Like this:

(It also helps to sort the cursor values by size to avoid negative differences…)

How do I make it work if I use acquired sound instead of simulate signal, thats when mine breaks.

p.s. cheers for the tips.

In which way it "breaks"?

Can't you run your VI anymore? Do you get any error? If yes: which one?

Why should the VI break? You get the very same DDT containing a waveform, you convert that to a 1D array of samples and you can select the same subset as with a simulated signal…
