Use the Sound and Vibration VIs to perform sound and vibration measurements. The Sound and Vibration VIs perform the selected analysis and allow you to view the results with the appropriate engineering units in standard displays such as magnitude/phase, real/imaginary part, and decibels on/off.

Note  Besides the subpalettes listed in the table below, this palette also contains the Fault Detection VI, Order Analysis VIs, Tachometer Processing VIs, and Torsional Vibration Measurement VIs subpalettes.

The VIs on this palette can return ranges of LabVIEW error codes or specific sound and vibration error codes.

Subpalette	Description
Display VIs	Use the Display VIs to display signals on several types of graphs and plots, including a colormap, waterfall graph, and an octave waterfall graph. If you have the NI Sound and Vibration Measurement Suite, you can use additional types of plots.
Distortion VIs	Use the Distortion VIs to perform distortion measurements.
Frequency Analysis VIs	Use the Frequency Analysis VIs to perform averaged and non-averaged, or single block, frequency analysis. The analysis is based on the FFT.
Generation VI	Use the Generation VI to generate different types of single and multitone signals, function generator signals, and noise signals.
Limit Testing VIs	Use the Limit Testing VIs to perform limit testing on waveforms, spectra, XY data, identified peaks, or scalar measurements.
Octave Analysis VIs	Use the Octave Analysis VIs to perform octave analysis, third-octave analysis, and fractional-octave analysis, including 1/1, 1/3, 1/6, 1/12, and 1/24 octave.
S&V Express Measurements Express VIs	Use the Sound and Vibration Express Measurements VIs to quickly develop and interactively configure sound and vibration measurements.
Scaling & Calibration VIs	Use the Scaling & Calibration VIs to scale an input signal measured in volts to the appropriate engineering units. You also use these VIs to calibrate microphones, accelerometers, or other sensors and to measure propagation delay with DAQmx or Traditional DAQ devices.
Single Tone Measurements VIs	Use the Single Tone Measurements VIs to perform single-tone measurements.
Sound Level VIs	Use the Sound Level VIs to perform sound-level measurements, including linear, exponential, and peak hold averaging. Linear averaging is also known as equivalent continuous sound level, or Leq.
Swept Sine VIs	Use the Swept Sine VIs to perform swept-sine measurements.
Transient Analysis VIs	Use the Transient Analysis VIs to perform analysis of non-stationary signals.
UFF58 File I/O VIs	Use the UFF58 File I/O VIs to write binary UFF58 (universal file format) and read binary and ASCII UFF58 files. Each UFF58 file consists of one or more functions. Each function contains 12 records.
Vibration Level VIs	Use the Vibration Level VIs to perform vibration-level measurements.
Weighting and Filtering VIs	Use the Weighting and Filtering VIs to apply a weighting filter on time-domain signals sampled at specific rates. You can choose from acoustic, telecommunication, radiocommunication, and human vibration filters.
