Can Anyone Recommend Software For Audio Editing?

As best as I know, what your are requesting is nearly impossible, the only thing that you can do is first you need to separate the audio file from the video file, (this i don't know exactly how to do), then you need to see what kind of an audio file is it,

in generally you need to lower the high frequencies channels, this is probably the only thing you can do, & it would not do exactly what you desire

this next software is for free it is very simple to use

http://audacity.sourceforge.net/
you need to download & install it

other then this you'll need a very expensive audio studio to do what you need, 7 even then they wouldn't do it 100%

I'm not an expert, but my father-in-law, is, he works a lot on video editing & animation with some of the best software's that are available on the market
