I can get a little more out of it. Attached.

I can send you the equalization curve.

EmEq.XML attached. Download and install it in Effect > Equalization.

I don't know you can do noise reduction on this. For noise reduction to work you have to have to be able to find clear noise with no voice. That's going to be rough.

I think I would equalize first. Noise reduction can produce choppy work and make further corrections sound terrible.

i had a clear area where there was no talking and so i did the noise reduction.

but i was reading the instructions with your effect (equalization) and i think it said to run the effect first and then noise reduction or maybe the other way around

See which one sounds best. You're not in "sound sweetening" now. You're in disaster recovery, so there are no rules.

I think EQ is best done after Noise Reduction http://manual.audacityteam.org/man/nois ... .html#Tips.
