Getting rid of unwanted sound in Vegas
I committed the cardinal sin of using my Sony VX-2100 cam’s built-in microphone when filming. Unfortunately the sound tracks in some of my footage contains camera motor noise etc. I learned (through hours and hours of searching through my clips) to edit these by looking for only crisp and interesting sound files and using these to match video footage.
Now to my question: I have some valuable clips where I dont believe I can match them with other audio files to be replace the audio in them. There is a constant hum kind of like a powerline or tuning fork sound.
Its very important to keep ambient sound as this is an outdoor bird film. Even flies buzzing add to the correct mood of the film. I tried a software called audacity. It did indeed get rid of the unwanted hum but the software seemed to slightly alter the bird calls and the result is that the audio is so squeaky clean it sounds unnatural. Any suggestions if there is another way I can tackle this one?
Thanks very much as always for letting me have access to expert help!

Can you upload one of these audio files?

Hello,
Sony has some plug-in https://www.sonycreativesoftware.com/noisereduction) that help with noise reduction as well as hum removal and other sound restoration items. They work really well and allow you to sample the “Noise” and remove just that sound. I use that as well as Waves noise and hum reduction, however those are much more expensive. In any case good luck!

The Sony Noise Reduction is a good option as Scott said, but first I would open your Track EQ that is placed on every Vegas audio track by default, and select the [Sys] 60 Hz hum notch using four stacked preset. This is specifically designed to remove 60 cycle hum. If that doesn’t work, BIAS Sound Soap should be able to remove it a lot cheaper than the Sony Noise Reduction plug-in and iZotope RX is the ultimate in removing all sorts of noise that even Sony Noise Reduction can’t remove.

Theo please accept my apologies for not replying much earlier. I was under a deadline to finish up a demo of the project and get it off to the reviewers. I know that youtube might not be the best platform to provide you the opportunity to listen to the unwanted humm in my footage but in case it helps here goes: Its not a long file and if you turn up the volume you should hear the problem. I used the switches/normal command in Vegas in the audio track to accentuate the problem.
Naturally for a nature film its super important to keep bird calls and flies buzzing in the film… I just want to eliminate the hum.Here it is:

Sounds Good John:
Now how on earth does one locate a tool called [Sys] 60 Hz hum notch using four stacked preset? Is it located in the FX section?
Very baffled.

Click on the Track EQ like you have in your picture and select it from the Preset: dropdown. It’s one of the presets.

You shouldn’t be embarrassed at all. Until you learn the application and work with it every day, it’s really easy to miss things because there is so much functionality. Now you will know where to look. (BTW, I’ve been using Vegas since version 3 so I’ve had a long time to learn where everything is) 😉

Thanks John
Do you think that iZotope RX can get rid of this annoying hum? I used switches set to normal funtion so that it makes it a substantially louder and more obvious. Also when you use a noise reducer software what about the idea of first editing the audio using the normal function in switches and then turning it off when you drop it into its home next to the video track.
Here is my file in need of help from izotope RX here:

Does the noise get louder and lower like that all on it’s own or are you changing the volume of it in some way? If the original tape goes up and down in volume like that then you will have to apply RX several times to the different parts but RX can definitely remove broadband noise like that. What you do is take a noise sample at a part in the audio that is only the noise and then apply it to the entire audio and it will remove the noise based on the sample and leave everything that is not noise.
