Background noise

This is something I sometimes have a problem with, the motor of my camera heard and I want to get rid of it. I found ways in my old editing software to lessen it but as Sony and its sound is new to me its still a little confusing. I've been messing around with the noise gate but is there other ways to lessen this sound? Any information anyone could give me would be very helpful.

What you need is a noise reduction fx. Unfortunately Vegas does not come with one. You can buy Sonys Noise Reduction which apparently is very good. I use a free sound editing app called Audacity which has a quite usable noise reduction function.

I also use Audacity to do noise reduction. PRR5345, it's fairly simple to do with that program and it's FREE. In VMS, you will have to ungroup the audio track of interest from the video track, then render only the audio to mp3, wma or other format Audacity handles. Then launch Audacity, import the audio track, do the noise reduction, and then export to mp3 or wma or another format that VMS can open. Google "Audacity", download it and then install it. You won't be able to use it from within VMS, however, like you can for Acid or Sound Forge.

I've done this process many times because the built-in mic in my Samsung SC-D365 Mini-DV Camcorder picks up the motor noise. I don't seem to have the problem when using my external mic since it's not in close proximity to the tape motor.

Thanks to both of you for your help and information.

I tried audacity and it seems pretty good. can you change the settings a little to get a more extreme noise reduction without getting that horrible buzzing noise that some base noise reduction programmes use

I managed to import it into vegas without a problem because the files I used are in windows, uploaded to vegas. (although to be honest I've found the sound to be better if you upload straight to vegas, although i don't know if that's just the attributes of the files themselves this early.)

Built-in-mic's is a curse.

PRR5345...

Over the years, I've had to play around with each individual audio track in Audacity. Each one has it's own set of issues. The neat thing about it is you can easily "undo" the noise reduction and "redo" it again making small changes until you get what you need. Since noise reduction is a 2 step process in Audacity, you may have to amplify the noise section slightly before you select it for step 1. I've done that successfully on occasion.
