I've got this really noisy audio file I'm

I was thinking, it would be really cool if I could run a clip of
the file that was just the noise(it's a recording of a discussion
for a TV broadcast, so when no one's talking, it should be
silent) and have the program output an average frequency content,
in some sort of format that another program could take it as
input and create a filter that would filter out those
frequencies. It seems like brutefir would be able to do the
latter part, but is there a way to automatically generate the
filter definition from the frequency content of a file? Is this a
feasable method of noise reduction? If it seems like it could
work, but there isn't a program to do it, I would be interested
in writing it, if anyone has any input.
If you are trying to clean up a file, a doubt the system you
describe above would produce results anywhere near as good as
Gnome Wave Cleaner.

C++ is a siren song. It *looks* like a HLL in which you ought to be
able to write an application, but it really isn't."
