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.

supercomputer in one's pocket....
