Hello Art,

Not sure what you mean by "live". Are you looking to use this on Real
Time Data (RTD)? There are "C" DLL libraries available if you want FFTs
with faster execution times. You could also look into purchasing a
specialized math program as well. Not likely you will find a Fast
Fourier Transform written using Excel worksheet functions and/or VBA,
unless the programmer was doing it for a math class, a masochist, or
insane, since it is already available in the Analysis ToolPak.

Sincerely,
Leith Ross
