Hi all,

I bought a cheap guitar-computer interface off of dealextreme:
http://www.dealextreme.com/p/guitar-to-usb-interface-link-cable-for-pc-mac-=
recording-130cm-32874

It works very well and GarageBand/Guitar Rig totally rock. Latency is
minimal as well. I don't think I can notice it with the proper
settings.

Anyway, there seems to be a very high frequency hiss sound on certain
amp models/configurations on both GarageBand and Guitar Rig (have yet
to try logic studio) which makes me question whether or not the guitar
interface is at fault. I want to do a spectrum analysis on the output
of the thing and see what's going on. Does anyone here know of any
good (free if possible) real time spectrum analyzer software for
Windows? I want to be able to view what audio is coming out of this
guitar interface.
