Anticipated for next release:

• Extensions to the new calculation engine.

Version 5.68.3

 NEW  on 11.11.2024

Major Update – EASE 5 Third Edition

EASE 5 Third Edition includes all features added since the introduction of EASE 5 Second Edition as well as the following new functions and tools that were not part of the previous release version 5.67. 
 

New features and improvements:

• Introducing Acousteer: acoustic simulations in real time!
  Direct SPL mappings can now be calculated at high speed and allow for interactive model changes with immediate visual feedback. Control and display are directly integrated into the main program.
• Calculations are performed at a frequency resolution of at least 1/24th octave bands using the accurate, complex-valued GLL loudspeaker data. Selectable result bandwidths include 1/3rd octave, 1/1 octave, 3/1 octave, Mid-band (400 Hz – 5 kHz) and Broadband.
• The full audio bandwidth from 20 Hz to 20 kHz is supported allowing to model subwoofer arrangements as well as to investigate low-frequency interaction. The Interference Sum switch enables or disables complex summation.
• One can choose between the Low, Intermediate, High, and Maximum spatial resolution settings equating to up to 200 000 mapping points. The spacing between adjacent mapping points scales with project size and is larger for larger audience areas.
• A user-defined color scale can be set to fix the color for the greatest and the smallest SPL value and make mapping displays comparable. By default, an automatic scale is used based on the maximum and minimum value of the computed map.
• Loudspeakers can be activated and deactivated for the mapping. Loudspeakers can be selected by mouse in the 3D view, in the tables, via processing blocks or selection sets and then turned on or off.
• Any parameter changes as well as any model changes are applied instantly and in real time, including loudspeaker locations, aiming angles, signal processing, and environmental parameters.
• Calculations are based on a highly optimized, hybrid CPU/GPU simulation engine supporting modern CPU and GPU computation capabilities. A regular, contemporary PC or laptop is sufficient to take full advantage of the Acousteer calculation performance.
• Calculations are currently limited to direct SPL on audience areas and will be expanded in future upgrades.

Bug fixes:

• Fixed: 3D engine may not recover after sleep and hibernate due to missing resources (v68.3).
• Fixed crash upon start of calculation. Related to tessellation of the specific geometry of an audience area (v68.2).
• Fixed bug related to local culture settings that may cause EASE not to start on some systems (v68.1).
• Fixed several errors related to user-defined material labels.
• Fix: Update properties window after assigning a new material from the search list.
• Fix: Initial display of measured RT curve may not show a solid line.
• Rare error fixed when importing erroneous GLL data.
• Several performance improvements for rendering, selecting, and mapping.

Version 5.67

08.10.2024

New features and improvements:

• Acoustic materials can now be modified directly from within the project***. This allows calibrating the modeled room to a measured RT in an interactive and direct way. The resulting new workflow enables the fast and efficient setup of acoustic models.
• Material properties window: For a selected material, the new window allows viewing and editing all relevant properties:
  • Material label and description
  • Absorption spectrum
  • Reset function for reverting to the original data
• Curve editor: The Materials in Use window was extended by a graphical display of all absorption curves:
  • The overlay graph can be configured to show all or only selected curves.
  • For modified materials the original curve can be shown as well.
  • Absorption coefficients can be changed in real-time simply by dragging the curve with the mouse.
  • Materials can be highlighted, hovered and selected.
  • The graph can be exported as a picture for reporting and documentation using the commands from the Tools menu.
• When modifying a material, the label of the original database material and its reference are maintained. Modified materials are stored along with the project and can optionally be saved to the global database.
• The reverberation time displayed in the Acoustic Parameters window now supports overlaying measured and calculated RT curves. When combined with the curve editor the necessary adaptations to absorption materials can be achieved quickly and intuitively.
• A new color selection dialog in the tiles view of the Materials in Use window was implemented.

Bug fixes:

• Performance of highlighting, multi-select by mouse and selecting selection sets significantly improved.
• Show points of selected audience areas also when faces are invisible.
