Re: Adaptive Limiter and Oversampling Question....

There are two potential reasons to oversample with a limiter:
1. To detect intersample peaks where the peak of a digital waveform after reconstruction (or some types of processing) is higher than the sample values.
2. To reduce aliasing that can occur from the distortion created (especially) by aggressive limiting.
The eZine references #1.
I would suggest using your ears for #2 by choosing a plugin/settings that sound good and not worry about the technical details. For modern plugins, the programmers will almost always upsample an appropriate amount if it's beneficial (or offer the option) - after all they want their plugins to sound as good as they can and the CPU hit from upsampling isn't remotely as relevant today as it used to be.
In order, then, to discover the limit of deepest tones, it is necessary not only to produce very violent agitations in the air but to give these the form of simple pendular vibrations. - Hermann von Helmholtz, predicting the role of the electric bassist in 1877.
