Anyone know of (hopefully free) software which will give a real time

If say you fed white noise into an amp and the output to the PC, it gives
a graphic of the energy at different frequencies - a sort of instant
frequency response trace.

Thing like Audacity can analyse a recorded sample afterwards - I was
looking for something which will do it in real time.


**If you have a 'smart 'phone' then there are lots of free apps that
will do what you want. Obviously, such software will probably run on a
tablet too. Ah, the joys of having the power of a 1970s Cray
supercomputer in one's pocket....

I want something a bit better and more convenient than a smart phone can
do. ;-)
