Brit also shared a slightly longer sample with me, which I took a stab
at applying Samplitude's native noise reduction filtering to. This
isn't a straight frequency filter; you provide a noise sample
(typically a selection of the source file) and it attempts to subtract
that sample in a tiled fashion from the original.
It can be very effective for stable noise (hiss, hum, etc.) but you
have to play with the various paramters to avoid the classic "rounded
FFT step" noise reduction artifacts. I can hear digital artifacts in
these results, but I nonetheless find it an improvement...
...but it's a bid hard to tell since they are present in the source
MP3 as well -- and the calls themselves have such an odd sound
themselves. :)

For reference, here's the original:

I played with applying additional parametric EQ to the post-NR file
but found myself taking the remaing edges off without making a
dramatic improvement to the remaining noise floor... but YMMV. :)
