The new features in ODEON 14 include:
Grid definition is now easier and more versatile than ever. The new 3D grid interface includes the foloowing features:
Parallel processing is being applied in more places allowing faster multi source calculations as well multi source auralisations. In ODEON 14, parallel processing has been implemented for:
The STIPA (Speech Intelligibility Index for Public Address) is available in Odeon 14. STIPA uses a subset of 14 of total 98 combinations of octaves and modulation frequencies applied by the full STI method (7 octave bands from 125 to 8000 Hz and modulation frequencies from 0.63 to 12.5 Hz).
MTI (Modulation Transfer Index) is the modulation transfer index for the octave bands 125-8000 kHz. These values helps determining which octave band needs improvement in order to improve the overall STI (by lowering background noise or reducing reverberation.
To include STIPA and MTI in existing rooms, enter the Define Room Acoustics Parameters, then click the Factory defaults button.
When loading multiple measured impulse responses, ODEON will in addition open the Statistics for Measurements display which will display all calculated extracted room acoustics parameters and statistics for them. The feature is automatically activated when more than one measured impulse response is loaded and when no room is already opened. When a room model is already in use the existinng statistics tools in the Multipoint Response can be used.
In ODEON 14, one more calibration method is added: the figure 8 microphone calibration. This is necessary for measuring the Early Lateral Energy parameter, which expresses the fraction of energy arriving from lateral directions within the first 80 ms (ISO 3382-1, 2009). For such a measurement a microphone with two channels is needed: An omni and a figure-8 channel. The sensitivities of these microphones should be adjusted so that the peaks of the two channels coincide. The new calibration procedure helps accomplishing this regularization, as seen in the following figure.
The calculation of headphones' equalisation filters can be controlled with the new Headphone filter design tool. An impulse response of a pair of headphones, measured with ODEON or any other measurement program, can be processed in order to obtain a filter that compensates the for the response. The goal is to minimize the influence of the headphones in the experience of listening to auralisations within ODEON.
The room achiving facility has been improved in ODEON 14. Checking one or two of the two Included checkboxes, makes it possible to include additional data files used in the calculations (directivity files, headphone files, grid colour scale files, wave files) which are available in the current PC. When unpacking an archive on another (or the same) PC at a later point, these files, if included, will be installed to the correct locations (as defined in the Program setup) if not already there.
The J and Shift+J shortcuts can be used for switching between jobs from within the 3DGRid display, making it easy compare a given parameter at a given frequency for different jobs.
Drag and drop support from within the Job and auralisation lists makes it simple to copy auralisation results from Odeon to a folder or indeed to a Power point presentation. Simply select one of the cells containing an auralisation result in the job or auralisation list. Then hold the left mouse key down and move the item to the desired location (e.g. in a folder in Windows Explorer or a slide in an open instance of Power point) and release the mouse key. The functionality includes impulse responses, anechoic auralisation input files, convolved auralisation files and mixed auralisation files.
A new Global Assign to layer button is available in the materials list making it easy to assign a material to all surfaces on a given layer. Select the desired material in the right table and select one surface on the layer of interest - then click the Global Assign to layer button.
In ODEON 14 it is easier to receive software and documentation updates. When a new update is available, a notification will appear, the download and installation process is done automatically by ODEON!, no more manual downloads or copy-pasting executables by yourself. This new update tool makes it possible to update not only the main application, but documentation and especial files like headphones filters, directivity files, new example rooms, etc, can be delivered to you more frequently. Of course, it allows you to stop the notifications if you want to update later.
