Below the improvements of Odeon Versions 9.1 - 9.2.
Updates for Odeon 9.2 mostly contain fixes of smaller problems, many related to Windows Vista. The adjustments are listed in this document.
A large part of the effort in updating for Odeon version 9.1 has been put into making the program convertible with windows Vista, but there are also new features as SuperStereo and editable receiver grids.
With the release of ODEON 9.1, Odeon is made compatible for Windows VISTA. Once installed, you'll notice that executable and DLL files no longer resides with your ODEON documents such as rooms and sound files. The program files have been "hidden" in the program files folder for protection. Similar the common application data such as program setup (Odw.setup), color layouts for 3DGrids (.clr files) and parameter scales for parameters to be displayed in 3DGrids (.GridScale) are stored in the application data folder of ODEON. The name of the application data folder may differ from one PC to another, but a typical name of the folder isWindows XP: C:\Documents and Settings\All Users\Application Data\Odeon9Combined.
It is possible to exclude receivers from being displayed in 3DGrid when the chosen parameter is over or under range for a receiver. This is in particular useful if some of the grid receivers are located outside the room - thus having values which are out of range. The settings are changed in the Options|Program setup dialog at the Grid colors tab.
Support for playback of auralisation results on a stereo set of loudspeakers has been implemented. This allows high quality playback in stereo on loudspeakers where stereo has previously been restricted to binaural playback over headphones. In order to to make use of this option the 2D Surround sound - Create impulse response option in the Auralisation setup must be checked and the loudspeaker rig must be defined appropriately as in the Define speaker rig dialog.Super stereo is an attractive output format because: a) Output can be played back on a conventional stereo system b) Output files from calculations in the auralisation list are compatible with standard audio CD's c) Stereo Room Impulse responses can be used with Streaming Convolution utility for instantaneous stereo playback, just like binaural results.
The Reason to call the output generated by two channel Ambisonics techniques for Super stereo is that this technique is capable of rendering sources outside the limits of the speaker rig (e.g. sound coming further to the left than the position of left speaker).
