Hallo.
I need to analyze a sound (LV 2011 / XP) in third of octave and make a limit for every octave .
I can acquire signal form the microphone in a range 20Hz/20Khz, analyze it in third of octave and make the A-weighting like I need.
I can also show on a chart the acquired signal and make a test on the level of the total band power.
I don't know how to extrac every level for every value of fequency and compare it with a value (different for every frequency) making a test for every frequency.
I don't have so much experience in manipulating array and cluster. i think that someone with more experience can give me some indication on how do it.
Attached there is a small sample vi that I had done just to clarify my application.
Thank you.
Best regards.
Emanuele
