NI Sound and Vibration Software

National Instruments sound and vibration software provides a complete software solution for all Audio, Noise and Vibration, and Machine Condition Monitoring applications. Based on an open analysis capability and a flexible measurement library, the NI Sound and Vibration Measurement Suite and NI Sound and Vibration Toolkit present a unique software-based measurement approach to creating customized applications.

Both software packages include the NI Sound and Vibration Assistant, interactive software for quickly acquiring, analyzing, and logging acoustic and vibration measurements. The Sound and Vibration Assistant introduces an innovative approach to configuring your measurements using intuitive drag-and-drop steps. Combining the functionality of traditional noise and vibration analysis software with the flexibility to customize and automate routines, the Sound and Vibration Assistant can help you streamline your application.

Sound and Vibration Analysis
 Sound and Vibration Assistant LabVIEW Analysis VIs
Description With the Sound and Vibration Assistant, you can continually interact with live data to modify analysis settings dynamically while logging data to disk for more analysis later. The software includes support for power spectra, ANSI and IEC octave analysis, sound and vibration level, order tracking, time data recording, Universal File Format (UFF58) file I/O, and report generation. NI LabVIEW analysis VIs are available for noise, vibration, and harshness (NVH); machine condition monitoring; and audio test applications. Express VIs and more than 50 ready-to-run LabVIEW example code bases are also included to shorten time to first measurement. Frequency analysis, transient analysis, and order tracking are among the available functions for developing a custom application in LabVIEW.

Below is a list of functions that come with each software package.
