Hi,

You can use "Mask and Limit" express VI to test the limit of your signal specified by a constant inside the VI's property wizard. Whenever the signal goes above the limit, a True/False signal is generated where you can connect an LED for indication.

pull out your sampled amplitude and compare greater than to the desired level and bool out the results to the LED software/hardware indicator....

Hi,

You can either compare the values from simple comparison OR use that "Mask and Limit" VI. Just connect the output of sound to it's input. Upload your VI if you still didn't get what I mean.
