Hello all,
I'm a student, I'm working on a video project. The video was shot in a large room with the aircon on, hence the microphone picked up a lot of background noise. I'm new to audio editing and I've tried adobe audition to remove the noise. I've had a bit of success but the edited audio has a echo, the volume is reduced and there is a strong emphasis on the letter "S".
I am posting a small sample of the audio, I was wondering if you any of you would be able to edit it for me so that I know what settings/filters/processes I can use to achieve the best sound.

Bring the clip into the edit side and highlight a small section of JUST NOISE then go to EFFECTS > NOISE REDUCTION > NOISE REDUCTION > CAPTURE PROFILE > OK ... Now highlight the whole clip and go back to the noise reduction filter, use the PREVEIW and BYPASS to check your settings and then OK ... The worst thing about the noise is like a dripping faucet at night you will be hyper sensitive to it but use extreme CAUTION to not over do it ... Start at about 60% and work up from there clicking the BYPASS off and on till you get enough of the noise out so it's not distracting but doesn't affect the voice if you take too much the voice can get really ugly ... Background is the worst since it covers a wide range of frequencies and trying to remove it will cause you to take away from something you may not want to take away from making it sound less than, or just plain ugly ... Going into spectral view might help also ... Anyway you look at it the background noise is going to be ....... WILLIE

As Willie pointed out, noise reduction is a tricky business
when the noise you want to remove is so overt. Linked is
an example of your clip using Audition's regular noise
reduction tools at (almost) max strength. You'll notice
that the offending ambience has been removed but what's
left in its hole is noise not dissimilar to mp3 compression.
Notes:
- The mp3 compression-type noise existed before the clip
was saved as an mp3.
- I've left a couple of seconds of the original file at the
beginning for comparative reference.
