Odeon version 5

Odeon 5.0 has been improved on a number of points, the most obvious being that a number of new graph facilities has been added in the program. Below follows a short list of some of the news:

Quick Estimate

The Quick Estimate algorithm has been improved. In its current version, only surfaces detected by rays emitted from the selected source will be used for the estimation of volume and active absorption area. This means that it is now possible to get realistic estimates with the statistical formulas even for small sub-geometries, such as a closed stage room in a concert hall geometry. Two new graph displays has been added to Quick Estimate, one which gives an overview of the reverberation times as estimated using the different statistical formulas and another providing an overview on the absorption provided by different materials.

Global Estimate

Two new graphs has been added to Global Estimate, a graph for evaluation of T20 and T30 and graph showing the Free path length distribution. The estimate of volume (which is not used in the calculation of the reverberation times) has been improved, only the surface areas, which are detected in the ray-tracing process are used in the estimate of the volume.

Single Point Response

Two new graphs has been added to the point response window and existing graphs, in particular the reflectogram has been improved.

The Multi point response

No less than seven new graphical displays has been added in the Multi Point window. The graphs covers:

  • Display of frequency dependent parameters
  • Display a selected frequency independent parameters
  • Parameter versus distance
  • Display of minimum, maximum and average values for a selected parameter
  • Spatial decay curves
  • Noise control display with interactive evaluation of the contribution from the different active sources at the different receiver positions.

The Grid response

Improved /selectable colour scales for colour grids (Options|Program setup|interface settings). An extra graph showing the cumulative distribution function has also been added in the 3DGrid display.

Improved printer dialogs

When printing from a window, which contains more than one display, a printer dialog allows the user to select which of the pages should be added to the printout. This new feature is in particular useful when printing from displays such as the Multi point where many graphs has been added.

Importing a room setup

A room setup containing sources, receivers, materials, grid etc. can be imported from another existing geometry using the the new Import settings from another room option, allowing easier comparisons across different rooms. A dialog allows the user to select which settings should be imported.

Other features

  • Improved Job list, sources can be activated directly in the Job list display.
  • Source and receiver data can be imported and exported in the new .SouRecScript format.
  • Geometries can be exported in the VRML format for presentation in a Internet Browser.
  • A list of preference views can be saved, edited and deleted from the 3DOpenGL view, in the same way as it is possible from the other 3D displays (using the Insert, Space and Delete Shortcuts)
  • A surface can be looked up in the Material list and in the 3DView using the number (shortcut F3) or a part of the surface name (Ctrl+F3) as the search criterion. This is in particular useful when dealing with complicated geometries.
  • Preference Manual scale setting can be loaded and saved from the Define grid menu.
