Requires: Sound and Vibration Measurement Suite. This topic might not match its corresponding palette in LabVIEW depending on your operating system, licensed product(s), and target.

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 VIs, Order Analysis VIs, Tachometer Processing VIs, and Torsional Vibration Measurement VIs subpalettes.

The VIs on this palette can return general 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.
Distortion VIs	Use the Distortion VIs to perform distortion measurements.
File I/O VIs	Use the File I/O VIs to save and load dynamic signals and measurement results. Use these VIs to read data from and write data to .tdms files and UFF58 files. Use these VIs with the standard File I/O VIs and functions to add custom properties, customize a file format, and write VIs to convert between file formats.
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 VIs	Use the Generation VIs to generate different types of single and multitone signals, function generator signals, noise signals, and chirp 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 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 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.
Sound Quality VIs	Use the Sound Quality VIs to perform psychoacoustic measurements associated with the human perception of sound. Use these VIs to perform sound quality measurements, including stationary loudness, time-varying loudness, sharpness, roughness, fluctuation strength, and tonality. The Sound Quality VIs comply with applicable standards for use with product evaluation and as part of a comprehensive sound quality program.
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 nonstationary signals.
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.
