Hello All,

There are numerous ways to get started with this application. First, you can acquire sound using the built in microphones in your Laptop or an external earphone. This sound can be brought into LabVIEW using the Acquire sound express VI (http://zone.ni.com/reference/en-XX/help/371361J-01/lvpict/acquiresound/).

Thereafter there are numerous parameters that need to be extracted from the sound signal like Bandwidth, Fundamental frequency, peaks in the spectrum, amplitude, shape etc.
