AFAIK, Soundforge & the simalar Cooledit have functions to sample the
noise & then subtract that from your programme - works best on
continuous, cyclical noise like hum or airconditioning units etc -

That's true. If you're lucky and can find a good section of voice you can
also approach it from the reverse angle. Sample the voice and set the plugin
to "keep the noise". This can sometimes work in a pinch when you can't get
at it from the other end. From that standpoint the voice may be more
"continuous" than the random noise.
