Problem in capturing audio signal

[akshay.joshi06]

Hello Everyone,

I am new to LabVIEW. I am trying to capture the sound signal, whenever a known frequency and amplitude is generated. I am recording the signal continously, but am unable to record the signal having only that particular frequency and amplitude.

Please help me.

Hi,

recording continously seems like a good aproach. Just check whether the specified frequency is present (with the desired amplitude) and only save/display/"do whatever you want to do in case of a match" when a match is detected.

Best Regards

There are some good Frequency Content functions in LabVIEW.  Look in the Waveform Measurement palette.  From there, you can get your frequency components and their amplitude.  When you see what you want, save the data.
