Problem in camparing two sound signals

[akshay.joshi06]

Gud Afternoon All,

I am trying to compare two sound signals in LabVIEW 2013, but facing some problem. My aim is to detect a particular sound say "Clap Sound". I have recorded that sound and added it into LabVIEW. the other signal is generated by using microphone. I am trying to compare both the recorded signal and generated signal, but unable to find any solution.

any help will be greatly appreciated.

Thank you

I am posting some of my results also.

the waveform named as "Signal" shows two waveform one is the recorded sample(brown) and other one is the sound generated (Orange). there are some moments when the comparision result comes true even when both the waveform overlaps each other. no able to understand the problem.

any help please.
