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......




If the noise is louder than the speech, you are pretty much stuck unless the
noise is outside of the main speech band of 300-3kHz.

Noise reduction systems either work on playing with phase relationslips oe
frequency controlled expansion..

If the noise is louder, it pulls the speech aswell as the noise.
