While typically useful in the display of individual data points, probing can also be used
to characterize data clusters. In [24] a digital waveguide mesh is used as a framework
for PMSon where the variable parameter is not a specific sound parameter but rather the
impedance values at junctures of the mesh. By creating an impulse at an arbitrary point
along the mesh and converting the output to sound different configurations of data will create
distinctly different auditory displays.
