Modeler Plus 6.5 has a unique feature that allows you to add background noise to your simulations. The software contains a library of pre-recorded noise files: the NCB curves, the RC curves and several custom noise files. We are now expanding the usability of background noise in Modeler® software by introducing two related applications, Modeler® NOISEGENERATOR and Modeler® NOISECONVERTER.
The first application – NOISEGENERATOR – is used when you have the spectrum of the background noise, but not a binaural recording of it. NOISEGENERATOR allows you to define the frequency response – either in Modeler or directly in the application – and the application will produce a loop of spatialized, binaural noise with the defined spectrum and a .noi file. Copy and paste the associated .noi and .wav files into your Modeler data folder, and then analyze background noise effects through Modeler and Auditioner simulations.
The second application – NOISECONVERTER – is used when you have a binaural recording of the background noise, and simply want to process it for playback in Auditioner. NoiseConverter reads in the raw binaural recording and outputs a loop of the background noise as a .wav file and a .noi file, that you copy and paste into your Modeler data folder, and then analyze the background noise effects through Modeler and Auditioner simulations.
For now the binaural recordings have to be made with the Earbuds and the ProRecorder, but we plan to extend this library based on requests from the field. If you need the Earbuds, please start with your local field engineer.
Enclosed you will find both applications along with manuals.
To run NoiseGenerator and/or NoiseConverter:
Install MATLAB Component Runtime, provided in the FTP folder. Upon successful installation, simply double-click on the NoiseGenerator.exe file to launch the application. An MS-DOS window will first appear, followed by the application itself. Please keep this window open in order to properly run the NoiseGenerator application. Clicking on the Help button in the lower right-hand corner of the application will bring up the User’s Guide.
The MATLABComponent Runtime is fairly large (150M) and can be found through the following ftp site: ftp://m6-files:email@example.com/
Here is the NoiseGenerator
NoiseGenerator is for now also located on the ftp site.
The NoiseConverter is attached to this note.
Have fun with the applications and please post any comments or issues you may have.
