I use Camtasia software. Awesome for recording courses.
I have towels/plywood/towels over the window. I then have 2 places I record.
With that I still need to edit a good deal out, and of course do noice reduction in Audacity.
I have to admit I am somewhat envious of the instructors who have a very quiet environment, and that is definitely on the must-have list for when we buy a house here.
I have a fairly quiet place to film, but to get rid of wind, traffic, and computer fan noise, I've found that a shotgun mic mostly does the trick. Any background noise that's left, I can pretty easily eliminate with Audacity using the Noise Removal plugin and maybe a noise gate if the noise is too embedded in the audio.
I was using iMovie for editing and now using Camtasia for the same. Although I don't have an outdoor shooting, the mic captures the noice of the ceiling fan which sounds just like the background noice on your video.
Both iMovie and Camtasia have a provision to reduce this ambience noice. I use them and it just works for me.
Vinod.
I am now using Built-in zoom and my voice cancelling and then adaptive noise restoration is adobe premiere pro. It improves the video a lot. I have a sony FDR-AX33.
hello
I use an audacity program to remove it
Have been in similar situation where i tried few things like using a very closed room or using zoom inbuilt cancellation,but more efficient then it found recently a nice AI based tool named Krisp ,which helps cancel all types of background noise with its advanced algorithms.
Give it a try,would be surely helpful.
I made this video showing how I get clean audio into my recording software and reduce the time it takes to edit after the fact.
I hope it helps and I am open to other suggestions and questions that you might have.
