This file contains information about LabVIEW support for the NI Sound and Vibration Toolkit 2009 and the NI Sound and Vibration Measurement Suite 2009. This file also provides you with help resources you can use while working with the software. Refer to the National Instruments Web site for a comparison between the Sound and Vibration Toolkit and the Sound and Vibration Measurement Suite.

New Features: Sound and Vibration Toolkit
New Features: Sound and Vibration Measurement Suite
Redistributing Executable Sound and Vibration Applications
The Sound and Vibration Toolkit 2009 includes the following new features in LabVIEW:
All standard VIs in the Sound and Vibration Toolkit and the Sound and Vibration Measurement Suite fully support 64-bit platforms. Express VIs and Express VI examples are not provided on LabVIEW 64-bit installed on a 64-bit platform. All Express VIs work on LabVIEW 32-bit installed on a 64-bit platform.
Use the new SVT Audio Filter VI to perform acoustic measurements by applying a selected audio weighting filter to the input signal. The SVT Audio Filter VI adheres to the AES17-1998 standards. The available audio weighting filters are Linear (no filtering), AES17 20 kHz Lowpass, AES17 40 kHz Lowpass, AES17 20 kHz Highpass, and AES17 40 kHz Highpass.
Note The following audio filters have modified specifications. The AES17 20 kHz lowpass filter specifies a stopband attenuation of at least 40 dB for frequencies above 48 kHz. The AES17 40 kHz highpass filter specifies a passband response deviation of no more than ± 0.5 dB for frequencies 52 kHz to 200 kHz.
Use the new Standardized Filter Express VI to perform common filtering processes on the specified input signal. You can select the filter category for your industry, including audio, human vibration, communication system, and A, B, C Weighting.
Note The following audio filters have modified specifications. The AES17 20 kHz lowpass filter specifies a stopband attenuation of at least 40 dB for frequencies above 48 kHz. The AES17 40 kHz highpass filter specifies a passband response deviation of no more than ± 0.5 dB for frequencies 52 kHz to 200 kHz.
The Sound and Vibration Measurement Suite 2009 includes the new Toolkit features above, as well as the following new features in LabVIEW:
Use the new Continuous Swept Sine VIs to perform continuous swept-sine measurements. A continuous swept-sine measurement uses a chirp signal to excite the device under test (DUT). A chirp signal is a signal whose frequency varies with time. The results of a continuous swept-sine measurement include the frequency response, distortion, and time-domain waveform and residue waveform of one harmonic.
Use the new Sound Quality Express VI to perform common sound quality measurements, including 1/3 octave spectrum, specific loudness, stationary loudness, loudness level, and sharpness. The measured specific loudness, stationary loudness, and loudness level comply with the ISO 532B standard and the measured 1/3 octave spectrum complies with ANSI, IEC, and JIS standards.
To run the Sound and Vibration Toolkit or the Sound and Vibration Measurement Suite, your computer must meet the following minimum system requirements:
You must be logged in with administrator privileges to install the Sound and Vibration Toolkit or the Sound and Vibration Measurement Suite. Note the following considerations when installing these products:
You can install all of your LabVIEW products—including the Sound and Vibration Toolkit or the Sound and Vibration Measurement Suite—using the LabVIEW 2009 Platform DVDs. You can find installation instructions for the Sound and Vibration Toolkit or the Sound and Vibration Measurement Suite along with activation instructions in the following locations:
Complete the following steps to install the Sound and Vibration Toolkit or the Sound and Vibration Measurement Suite on Windows Vista/XP/2000:
If you want to redistribute executables built with the Sound and Vibration Measurement Suite or any of its components, you must purchase the appropriate NI Sound and Vibration Software Run-Time License. The part number for the NI Sound and Vibration Software Run-Time License is 779875-01. Contact National Instruments to purchase the NI Sound and Vibration Software Run-Time License.
The version of LabVIEW in which you install the Sound and Vibration Toolkit 2009 or the Sound and Vibration Measurement Suite 2009 determines the way in which you can access the help.
Refer to the LabVIEW Help, accessible by selecting Help»Search the LabVIEW Help in LabVIEW, for information about the Sound and Vibration VIs.
Select Help»Sound and Vibration Measurement Suite Help in LabVIEW for information about the Sound and Vibration VIs.
You can find LabVIEW examples for the Sound and Vibration VIs in the labview\examples\Sound and Vibration directory.
You also can find LabVIEW examples for the Sound and Vibration VIs using the NI Example Finder. Select Help»Find Examples to launch the NI Example Finder. On the Browse page, the Sound and Vibration example VIs are located in the Toolkits and Modules»Sound and Vibration folder.
You can access the software and documentation known issues list online. Refer to the National Instruments Web site for an up-to-date list of known issues in the Sound and Vibration Toolkit or the Sound and Vibration Measurement Suite.
The following items are the IDs and titles of a subset of issues fixed between the Sound and Vibration Measurement Suite 7.0 and 2009. If you have a Bug ID, you can search this list to validate that the issue has been fixed. This is not an exhaustive list of issues fixed in the current version of the Sound and Vibration Measurement Suite.
| Bug ID | Fixed Issue |
|---|---|
| 126187 | Fixed the Waterfall Plot to no longer fail while copying data when reading saved waterfall data from 5.0. Use "Make Current Value Default" when saving the waterfall plot in 5.0 to allow the data to be saved and reloaded. |
| 130372 | Fixed SVFA analysis subVIs to be re-entrant to leverage parallel execution. |
| 134373 | Fixed the following modifications to reduce memory usage for the Sound Quality VIs: avoid unnecessary building of 2D array for processing of blocks with overlap, consolidation loops to avoid building and then immediately tunneling back into arrays, and avoid unnecessary coercion to extended precision. |
| 148603 | Fixed the Octave Analysis Express VI to display multiple plots correctly. |
