Release Notes | VELO 2026
VELO 2026 SPRING UPDATE
VELO 2026 is now available, introducing a range of new features and software enhancements across all applications. This release focuses on new functionalities, improved performance, and a more refined user experience. Below, you will find an overview of the latest features, organized per application and indicating their availability across the Lite, Standard, and Pro tiers, providing a clear view of what to expect in this new version.
Scan&Paint 2D
- Animated visualization of particle velocity and sound pressure datasets when using a reference sensor, enabling ODS analysis.
- Advanced controls to adjust relative phase delay in animated colormaps.
- Support for the Color Tracking Cap (PU Gen 2), enabling color tracking while maintaining LED visibility.
- Improved user experience during color selection for probe tracking.
- Enhanced UX using the outline tool, applying auto-range only to selected area.
- Additional controls for rotating background images.
- Enhanced interpolation when excluding multiple data points.
Operational Deflection Shapes
Operational deflection shapes provide a dynamic representation of structural behavior based on phase information. When measurements are performed with a reference sensor, the system reconstructs and visualizes the operational motion of the scanned surface.
By moving beyond static plots, this feature enables users to observe vibration patterns and mode shapes as they evolve over time, offering deeper insight into structural dynamics and energy distribution.
Color Tracking Caps
The Color Tracking Caps enable reliable probe tracking in Scan & Paint 2D measurements when infrared (IR) tracking performance may be limited. Designed for use with PU Gen 2, it provides a clear visual marker for color-based tracking.
This allows accurate probe localization, supporting stable and efficient measurements in outdoor setups or in the presence of direct sunlight.
Scan&Paint 3D
PRO
- Animated visualization of particle velocity vector fields and sound pressure datasets when using a reference sensor.
- Advanced controls to adjust relative phase delay in animated datasets.
- Export of measurement results and geometry in *.glb format for directly manipulating 3D camera view within third-party software such as Office Apps (PowerPoint, Word, Outlook and others).
- Enhanced "Show Capture" toolkit to analyze individual measurements, including now also an option to display time-corrected data.
- Improved auto-save for sound power panel-ranking tools.
GLB Export for 3D Workflows
Measurement results can now be exported in GLB format, enabling direct integration with modern 3D tools such as Microsoft PowerPoint.
This allows users to present and share results in an interactive 3D environment, improving communication across teams and making complex datasets more accessible to non-specialists.
Animated vector fields and colormaps
By processing probe signals together with a fixed reference sensor, cross-spectral phase information can be used to reconstruct the relative motion across different areas of a complex sound field. By sequentially applying phase shifts, this motion can be visualized, revealing complex sound radiation behavior directly from measured data.
In-Situ Absorption
PRO
- Estimation of material parameters based on acoustic impedance measurements, including airflow resistivity, effective sample thickness, and viscous characteristic length.
LITE, STANDARD & PRO
- Simplified workflow with the removal of the measurement setup tab.
- Improved user interface in both the free-field calibration and capture tabs.
- New optimized sample definition window for more efficient creation of material processes.
- Enhanced plotting behavior in the free-field and capture tabs, displaying raw datasets upon selection with support for multi-selection using standard controls (click and drag, Ctrl + click, Shift + click).
- Expanded process definition with additional settings, including user-defined probe-to-sample and probe-to-source distances.
Expanding non-destructive testing capabilities with Model Fitting
The new model fitting functionality enables users to derive key material parameters by fitting measured in-situ impedance data to the Johnson–Champoux–Allard–Lafarge (JCAL) model. By combining sound pressure and particle velocity measurements, the system estimates parameters such as airflow resistivity, effective thickness, and viscous characteristic length under realistic conditions. This provides a more in-depth interpretation of in-situ measurements, supporting accurate, non-destructive material characterization and translating measurement data into physically meaningful material properties.
Enhanced plotting for in-depth data analysis
The improved plotting functionality enables direct inspection of raw sound pressure and particle velocity spectra at every stage of the measurement process. Users can analyze individual captures or multiple selected datasets to evaluate spectral variations between captures before combining free-field and sample data into a final absorption result. This provides greater insight into the underlying data and gives users more control and confidence in the analysis.
Acoustic Shape
- User-defined FFT settings are now preserved within processes and automatically reused in subsequent sessions.
- A cursor indicator has been added to the “show-capture” display, providing contextual information about plotted arrows.
- A color bar with adjustable range controls has been added to the “show-capture” view for improved visualization control.
- The arrow selection tool in the Analyze tab now includes extended metadata such as capture name, probe details, and selected time range.
- A clear error message is displayed when the sample count is insufficient for coherence analysis.
- Power Spectrum processes now support A-weighted reactive intensity and A-weighted velocity.
- The time range selection window now includes references to the beginning and end sample for improved time resolution.
Improved user experience for faster analysis
The latest Acoustic Shape improvements streamline the analysis workflow of non-stationary problems by reducing setup time, improving visual clarity, and providing more contextual information during data inspection. With faster access to relevant settings, clearer feedback, and enhanced control over visualization and selection, users can interpret results more efficiently and make informed decisions with less effort.
ANALYZER
LITE, STANDARD & PRO
- Interactive legend controls allow quick adjustment of displayed datasets when working with multiple measurements simultaneously.
- Improved user experience with a faster and more responsive process tree.
General VELO Platform Updates
- Sensor and probe objects can now be directly linked to DAQ channel configurations, enabling automatic application of AC/DC coupling and ICP settings.
- Time-range selection has been refined with improved resolution and integer-based sample range fields for more precise control.
- Octave-band filtering is now available within the snapshot tool, expanding post-processing capabilities.
- Automatic software update checks ensure users remain up to date with the latest improvements.
Faster Octave Conversion in Snapshot Analysis
Conversion from narrow-band to octave results within the snapshot window has been added for improved data analysis. This allows users to generate octave-band representations more quickly during post-processing, enabling faster iteration and more efficient analysis workflows.
