Beware of killing intelligibility even if your first impression is that a
given process helps audio quality. Losing low-energy consonants
can definitely make dialog harder to understand.

There seems to be an absolute plague of unintelligible dialog in
current feature film mixing, and one suspect is the various dynamic
noise reduction processes that are popular. I started to doubt my
hearing, except that older films seem to sound just fine.

This trend is a real mystery to me. In the good ol' days, dialog
intelligibility was the #1 goal in motion picture and television
sound.

I have some recordings of people speaking, which are obscured
by a
high degree of noise; the recordings being from aircraft, subway
trains (the Tube), general outdoor/street noises. I need to keep the
speech intact as much as possible, while reducing noise; said
noise
being generally much louder than the speech.

Is this at all possible? Can an app like Soundforge do it, I see there
is a Noise reduction option with SF? Are there other specialist
(Windows) apps which might work, or any audio editing apps
which are
reputable for this application?

thanks......
