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.

You could use something from the set

!IyoScope / ROXScope /ROXMiniScope which I wrote that do this. They let you
switch between 'scope' and 'FFT' displays. Available from

http://www.audiomisc.co.uk/software/index.html

source code included. Not yet bothered to do a version for later RO boxes
as it'd need to use the USB Audio which most RO users don't have kit for,
alas.

However the above are for Linux and RO, not Windows. The snag being that
the !IyoScope relies on the hardware specific to the Iyonix. However I'd be
surprised if there weren't lots of alternatives.
