Info

een carried out is displayed in the rightmost column and should never exceed 0 dB. The recording level corresponds to the recording level on a tape-recorder. If you wish to compare different simulations you should use the same recording level. Creating multi channel auralisation is by nature a little complicated and you should get familiar with one-channel simulations before using this feature (the mixer). Multi channel simulations can be created using the mixer in the auralisation display (the two rightmost tables). The mixer allows you to mix together up to 300 (one-channel) simulations from the Convolve BRIR and Signal file table. The simulations can only be mixed together if they: use the same receiver position (Point Response Receiver) use the same orientation (Receiver towards source) To check this, scroll through the Convolve BRIR and Signal file table and view the receiver column (Rec.) and the Receiver towards source point, which is displayed as a red cross in the corresponding 3D display. Extended Auralisation examples with complete orchestras Installed with ODEON 10 are a number of auralisation setups where entire orchestras have been modelled for auralisation in a concert hall and in an opera. The installation includes music pieces of Beethoven (21 channels), Bruckner (47 channels), Mahler (39 channels) and Mozart (11 channels). To listen to these auralisations: Open one of the rooms in the Orchestra folder (e.g. C:\...\Rooms\Orchestra\ComptonVerneyOpera.par) Open the JobList (shortcut Ctrl+Shift+J) Calculate all jobs in the JobList (shortcut Alt+A) Once the calculations have finished, in the Auralisation Display, play the various tracks (shortcut alt+s) These auralisation samples include many setups that tells ODEON how jobs and wave-files should be combined into a few final mixes. It is likely that you will want to listen to auralisation in other receiver positions than the predefined ones. The fastest way to do this: Make a copy of the file set, using the File|Copy Files menu entry (just include room files when prompted) Enter the Source receiver list (shortcut Shift+Ctrl+S) and change the coordinates of the predefined receiver (double click the receiver in the receiver list Open the JobList (shortcut Ctrl+Shift+J) Calculate all jobs in the JobList (shortcut Alt+A) The anechoic recordings have been created by Helsinki University of Technology. For use of the anechoic orchestra recordings, delivered with the software please see section 8 of the license agreement. Other facilities in ODEON Apart from the features demonstrated in the above tour, ODEON also contains facilities for: Calculation of transmission through walls – this issue is covered in Appendix C. Copying the project files generated by ODEON (available from the Files menu item) Deleting calculation files or result files (available from the Files menu item). 2-27
Archiving project files in one single compressed /zipped file, for efficient and safe storage or for easy posting by e-mail (available from the Files menu item). Tools for detecting errors in a new model, e.g. warped or overlapping surfaces (available from the Toolbar dropdown menu). Setup for printouts (available from the Options|Program Setup menu item). Export of calculated data in ASCII /text format for use in a spreadsheet or other post processing. 2-28
