That one is a lot more expensive than the True Audio.

I have had so much trouble with these problems, that I wouldn't even attempt 
to cope with the ground loops and hum issues that would inevitably result 
from using any kind of audio test software with a computer with a.c. supply. 
I have a laptop that is faster, has a bigger HDD and more memory than my 
regular computer has, so I would install the spectrum analyser in the laptop 
and run it off battery-only when using the analyser.  It looks like that 
software could convert a laptop into a lab instrument that would be more 
expensive than the laptop itself if purchased in the form of a dedicated 
unit.
