Real-time noise reduction software?

I was wondering, is there some software that automatically removes noise in real-time? Say, I connect my CB Radio to line-in, start an application and get rid of the background white noise  Or maybe the big audio editor suites can do that in real-time too, like Adobe Audition (I really liked its Adaptive Noise Reduction effect)?

Thanks in advance

I'm not sure you'd be able to get good noise reduction in real-time without latency issues. Noise reduction software typically looks at big chunks of samples, say 4096 (or more), at a time, so there is 4096 samples of latency (around 1/10th of a second with a 44.1kHz sampling rate.)

Such latency would be negligible with my use in mind...

I think Cedar Audio is still the technical leader in this field. I played with DNS3000 real-time noise suppressor at the AES show this fall. Magic audio shit (in a good way).

We had a demo of Cedar Audio at work this last spring and it was truly impressive. But with a $30,000+ price tag, impressive should be in the description.
