Remove Drone Noise from audio

[paland89]

Hi,

I am making a documentary about a climbing trips we had. I attached a lav-mic to one of the climbers, and I also flew the drone close by. Naturaly you can hear a lot of drone noise when the climber is talking in the microphone. Is there any way to remove the drone noise and clean up the audio? I have tride some with the noise reduction feature in audition, and it works OK - but it introduces a lot of strange sounds as well. I am now looking for a better solution.

Any tips? Any recomended tutorials?

Thanks!

That's almost certainly because you overdid the NR in a single pass. Our normal recommendation for all NR is to take off smaller amounts in more passes, re-sampling the remaining noise each time. Also, increasing the FFT size helps - a lot. So, take only 3-4dB at a pass, and do about three of them, with varying FFT sizes, most of which should be of higher values and one of which should be the highest you can set it to.

Thanks a lot for your reply. Some of this is quite new to me. Do you know of any good tutorials showing what you said?

Thanks!

The one built in to Audition is quite helpful. Go to the Help menu and select Audition Learn and then the Noise Reduction tutorial.
