I'm an American ex-pat living in Sosua, Dominican Republic, and currently working on a project doing video of the musicians that roam Sosua Beach trying to earn money entertaining the beach goers. Because it is not a controlled environment, not uncommon to get background noise, such as muted chatter.

I bought AudioDirector today because the video on removing background noise looked like it was something that I might be able to do, even with my limited knowledge of working with audio. However, when I opened the program I found that version 4 is not the same as used in the tutorial. The steps shown in the tutorial are not only for when you have a segment that contains nothing but the unwanted sound.

There is now "Auto Denoise" and "Noise Reduction", with "AutoDenoise" being the one I must use,it is for audio recorded outdoors, in room with poor acoustics, etc.

Auto Denoise has 2 sliders: "Sensitivity" and "Dry-Wet mix". The default for "Sensitivity" seems to be 50% and "Dry-Wet mix" seems to be 100%.

I tried that and could hear no difference.

I am at a complete loss as to how to proceed. I'd like to reduce the background noise if I can without reducing the the loss of quality of the audio I want to keep.

Any guidance anyone can give me will be greatly appreciated.

Hello kendp,

Welcome to the AudioDirector forum.

Firstly, your observation is absolutely correct. The screen captures for the tutorial http://youtu.be/qT7JtQrUNWk were recorded using AudioDirector 3

AudioDirector 4 has some refinements, one of which is the Dry-Wet mix
- just to explain, the Dry-Wet mix is the mix between the original (dry) recording & the restored (wet) audio
- this can minimise loss of sound quality when applying noise reduction

If you are able to select a sample of the noise (as shown in the image above), you'll get a much better result than with Auto Denoise, at least that's what I've found.

I'd like to reduce the background noise if I can without reducing the the loss of quality of the audio I want to keep.

Unfortunately, that's a difficult thing.

Perhaps if you could provide a sample of the unedited audio members could test and offer advice about settings.

Thanks for the reply. Yes, I agree it would be better to have just the sound that i want to eliminate, but there isn't enough at present. I will shoot the videos again, this time making use of a tip I read in my search today. The author recommended pausing for 10 seconds before starting to shoot, with the only noise to be heard being the background noise. Then repeat this at the end so that you have about a 10 second block of background noise before and after. That made a lot of sense to me and I can see how it would make noise removal much easier.
