How Can I Specify a Frequency Range Beyond the Audio Range In Octave Analysis?

Solution

In order to perform 1/3 Octave Analysis outside the 20 Hz - 20 kHz range, use SVT Fractional-octave Analysis [ANSI].vi or SVT Fractional-octave Analysis [IEC].vi found in Sound and Vibration functions palette. Specify the desired Frequency Range (low and high frequency limits) and set the Bandwidth to 1/3 Octave

Additional Information

If you want to perform Octave Analysis outside the audio range in SignalExpress environment, you can do it by using Run LabVIEW VI step containing code above.
