Check out clam-oldapps/trunk/SDIFDisplay from the svn. I just added an 
SConstruct file and compiled it. It is an old-app so... well.

I think SDIF expert was Maarten. You have him closer than us ;-)

For me was natural finding such large SDIF files as they contains several 
spectra and more information for each frame, and each spectrum has the same 
size of the audio or even more considering zero padding.
