NI sound and vibration software provides a complete software solution for all acoustic; electroacoustic; noise, vibration, and harshness (NVH); and machine condition monitoring applications. Based on an open analysis capability and a flexible measurement library, the Sound and Vibration Measurement Suite and the Sound and Vibration Toolkit present a unique software-based measurement approach to creating customized applications.

For a more complete comparison, refer to the Sound and Vibration Software Overview and Comparison below.


The Sound and Vibration Measurement Suite contains the most comprehensive collection of LabVIEW analysis VIs for noise, vibration, and harshness; machine condition monitoring; and audio test applications. Express VIs for power spectra, frequency response, ANSI and IEC fractional octave analysis, distortion measurement, order spectra, and color map processing are included to shorten time to first measurement in LabVIEW. You can quickly and efficiently begin applications with more than 50 ready-to-run LabVIEW example code bases provided in the Sound and Vibration Measurement Suite.

Recommended Hardware
For sound and vibration data acquisition, NI recommends DSA devices. With 24-bit ADCs and DACs, integrated antialiasing filters, and IEPE conditioning for microphones and accelerometers, NI DSA devices are designed for acoustic and vibration measurements.
