hahaha Yea, this is quite an interesting topic which my father wanted to work on way back and just passed it to me (my father is a university professor btw). The data I acquired seems reliable in the mucous-like and cooked rice-like - but there seems a lot of noise at leather-like. My adviser and my father said that I just use recommendations for further study since this is just an undergrad thesis

First of all remove the Fourier transform vi there is no need for that. The tone measurement express vi make the complete work for you. You only need to wire input data (wavfile data/AI) and specify a approximate frequency for the peak your looking for (possibly specifiy some other parameters).
To read a wave file you find them in the palette Programming\Graphics and Sound\Sound.
Rather than attaching VI paste a screenshot of your diagram, you will get a better respones, fast for us to see your problem.
Thank you very much for replying :worship: I'll prolly mostly redo the block diagram with your suggestion.
hmmm...is there a possibility that the tone measurement will output the FFT of it? I've been trying hours trying to figure that out - but no luck. cause i noticed that there is an Input Signal and a Result Preview when you select the properties of the tone measurement. I will most likely be using the amplitude since i need the peakpoints. If it is possible - kindly please post how asap. as i'm desperate
thanks again in advance
