For me, it looks like KmPlot is absolutely suboptimal for such kind of tasks.

Such sonification can be easily made with some CAE application like Scilab or 
Octave. Even Python with NumPy can be handful to do such things, but not 
KmPlot.

KDE has other good software for data analysis of this kind (Kst and LabPlot). 
These applications are not just advanced plotters (more advanced than KmPlot). 
They can analyze data, transform them and write the results into files.

KmPlot is absolutely not of that kind. It takes the equation and shows 
*visual* results. It can analyze data a bit or save them as a figure. It can 
be controlled through DBus (Kst and LabPlot can be controlled too) but it just 
not tailored as a computational mill of any kind.

Sorry. :'(
