I am a real audio rookie. I have some footage from a guy that has terrible wind noise. Is there a good way to reduce the roar and still hear the people talking.
Thanks

You can try using the EQ. Set the low filter for the sharpest slope of -18db per octave. Move the control point down to attenuate the low frequencies. Then slide it across the frequency axis slowly until you're reducing the wind noise without harming the vocals. You'll need to experiment with the frequency and the amount of attenuation to make the best improvement.
After that, you could also give a slight (3 to 5db) boost with a medium width to the frequencies around 2.5kHz. to help make the voices stand out.
You may also want to roll off the high frequencies some to reduce the other artifacts of wind noise that are less noticeable than the low rumble but occupy the upper frequencies.
As with any EQ, use the minimum amounts necessary to get the job done and listen carefully for doing more harm than good.
Lastly, you won't be able to totally fix this problem, just improve it some.
While NR 2 is awesome at what it does namely removing constant narrow spectrum noise it will fail miserably (as anything else would too) at removing wind noise or any other wide and varied spectrum noise such as crowd noise, coughing, cheering and other ambiant noise.
Even ambiant echo, in reality concidered "impossible" can be reduced with convolution verbs such as Acoustic Mirror using totally dead impulses like "carpeted bedroom" types may be improved at best. Wind noise is more "impossible" yet.
The sad truth is there is no real way to address this type of noise in post. One must take pains during the recording process to avoid such problems with close micing, wind socks etc..
