Generating an Extended Signal from a Short Duration Signal
Signals generated from numerical simulation data of a physical model (such as Mechanical or Fluent simulations) are often too short to be perceived well. Generating an extended signal enables you to listen to a longer sound. In addition, the longer signal can be better analyzed, such as for psychoacoustic indicators.
Note: The method used for the generation is based on the spectrum of the short signal. From this
spectrum a longer signal is generated. This longer signal is stationary all along its duration;
that is to say there are no transient events and the spectrum is constant all along the
signal.
To Generate an Extended Signal from a Short Duration Signal:
The extended signal is saved.
