One thing that will help is having the best soundcard you can get to
record onto, then from there you could possibly fiddle with some of the
filters on ecasound to try to reduce the hiss layer in realtime. There's a
program from my old teacher Tom Erbe called soundhack which can nicely
slice off hiss, but he hasn't released the java version yet (its a mac
program for now :-( ). Poke around the ladspa project as well, someone has
probably made a noise reducer plugin out there. Also Csound can be used
for this type of processing, maybe someone out there has a decent orc/sco
for hiss reduction.

I have already tried Audacity's built in noise reduction effect. It is very easy to use, but the resulting file has some noticeable sonic type noise (sort of a low level whistling) during the quite passages. This occurs even when I apply a small level of NR.
