This procedure describes how to create a harmonics model file controlled by one
parameter from a signal and its associated RPM profile.
Prerequisites: You must already have a sound file (a recording or simulation) that contains the
evolution of the targeted harmonics. This signal will have an associated RPM profile that
enables the software to analyze the level of the harmonics.
To create a model of a broadband noise source signal:
-
Get the order levels vs time for your signal by following the procedure in
Order Analysis: Displaying Order Levels in a Graph
-
Once order detection is complete, click .
The Signals to export dialog opens.
-
Under Data selection for export, select the required data.
-
Under Unit of the X axis for export, select
RPM and enter a Step value.
-
Click OK.
The text file created is directly compatible with the Sound Composer’s
Harmonics Source (1 parameter) source-type option.
A harmonics source model with one parameter can also be created manually by filling a text
file with a series of spectra, according to the expected file format described in Harmonics Sources.
