Hello,

I have footage in which I have the sound of a slamed door while the person is talking, is there a way to eliminate this sound or at least make it less clear.

I use Cool Edit Pro 2.0 as editing tool, is there a simple way to fix it? I have very basic knowledge.

Thanks.

Adobe Sound Booth may be able to do it. I think you might be able to download it for a free trial at the Adobe Site.

Hello Mike,

Isn't possible with Cool Edits...seems like a very powerfull software, I already use it in my productions...I remove noise and pop the sound, it must be able to to it also.

But I tried to download the software you mention. Does it has a special feature to do it automatically or are there step to fallow??? Link to the steps? or maybe in its help menu?

Thanks

To reduce volume of door slam in Cool Edit Pro 2, left click and drag to highlight section containing 'door slam' data, click 'zoom to selection' (immediately to the right of the record button). Repeat if necessary until you can distinghish just the 'door slam' peak. Highlight this data from nearest zero crossing (centre line) at start and finish of 'slam' peak.

Left click 'Effects' from top toolbar, then 'amplitude' and 'amplify' (or just click on 'Amplify, Fade in, Fade out' button if you know where that is) and set attenuation to match surrounding levels.

Note that you will also attenuate any spoken words that coincide with the slam, but there's nothing you can do about that I'm afraid. Shouldn't be too much of a problem if you are just attenuating the short 'door slam' data.

In sound booth you can bring the audio in and go into its vector form. You will be able to "see" the door slam. Then click "Remove a Sound." You then highlight the area of the door slam, and simply turn it down to nothing. That leaves the rest of the sound at that instant intact, expect if it is exactly the same pitch of course.

A more manual method of removing the sound would be to open the audio file in something similar to Sound Forge.
Duplicate the audio file so you have two versions.
Isolate the door slam sound in one of the tracks and try and remove everything else, so all you have left is the sound of the door slamming.
Then invert the waveform and recombine it with the original, this should be quite effective at the removing the unwanted noise.

Hello everybody,

Thanks for the reply and also for the steps, I'll be trying the options after I finish the video edits and I'll post how it went either today or tomorrow if anyone care to know.

Thanks again!

Hi Jose,

Incidentally, since a door slam is fairly short, if the talent spoke the same word elsewhere, you might consider using a cut-and-paste to over-write the door slam.

Enjoy, Michael
