These Vis allow you to see frequency and amplitude as a function of time.
These Vis are a modification of the Sound and Vibration example Sound Level Meter found in the NI Example Finder under Toolkits and Modules » Sound and Vibration » Analyzing and Processing Signals » Sound Level Measurements. The Vis are modified to show frequency as a function of time by using the Extract Single Tone Information.vi.
Requirements to Run
LabVIEW 8.6 or compatible
DAQmx 8.7.2 or compatible
Sound and Vibration Toolkit
Nothing for simulated version
Typically NI DSA devices are optimal for sound and vibration applications, however most NI DAQ boards with analog input could be used.
Steps to Implement or Execute Code
Set the Physical Channel.
You can chagne the sensor sensitivty, weighting, and frequency range. However, this step is just optional.
