My recommendation as always for any kind of noise removal is iZotope RX7. If it’s beyond your budget, then I would check out Klevgrand’s Brusfri. Check this video coz your sample is quite similar.

I applied a Noise Gate at -43.8 db in Sound Forge which is just above the noise/hum.

@john_dennis
Vegas Pro is praised again and again because in the first phase it was an audio program that only "learned" video editing later.
However, if there are specific questions - such as here - reference is usually made to more or less expensive additional tools.
Vegas Pro itself has a noise gate that is deceptively similar to that from Soundforge - with a few restrictions.
Wouldn't your solution be possible with Vegas on-board equipment alone?
Or are there significant quality-related or user-friendly losses?

I use(d) always the old Sony Noise Reduction

@walter-i.

"Vegas Pro itself has a noise gate that is deceptively similar to that from Soundforge - with a few restrictions."

Yes, it does.

"Wouldn't your solution be possible with Vegas on-board equipment alone?"

Yes it is.

"Or are there significant quality-related or user-friendly losses?"

I don't think there is any difference in the quality between Sound Forge.

• In Sound Forge one can select a region that should be noise free and run Tools / Statistics to determine where to set the gate threshold numerically.
• The same can be accomplished in Vegas by looking at the Meters and noting the peak(s).
• Some of my old habits probably won't die before me.

Wow, the noise gate plugin in Vegas works wonderfully! I had a guitar pedal that was a noise gate, but couldn't figure out how to use the thing, but this works even better. Thank you for the instruction on it, very helpful indeed.

Lot s of ways to eliminate the pre-music noise. The NR-2.0 noise reduction plug-in will attenuate the noise. If you do not have a plug-in, a volume envelope can attenuate the few seconds as well. The event could split as well, totally removing the initial noise section or just reducing gain on the event with the noise. Either way -12dB of attenuation brings the noise down to -60 dBFS (inaudible at typical PB levels) When the music guitar starts, that should mask the BG noise. A noise gate / expander is another option,

On this same topic of noise.... The noise gate gets rid of the noise when the guitar is not being played, however, if you turn up the volume and listen you can hear hiss and some high pitch what almost sounds like a beep for lack of a better description. Is there also some way to get rid of that noise so only the sound of the guitar is heard? Here's a longer piece of the audio, with @john_dennis's noise gate setting applied:

Do you hear it in wav file too?

If you mean on the timeline, then yes, I can hear it there too

When the noise section is normalized up, I hear what sounds like amp buzz and some extraneous ambient noise. I do not hear anything that is frequency specific, but my hearing ain't great after four decades of high SPLs in the music and pro audio biz.

So the noise gate is only for removing noise when nothing is being played, is that correct?

The other noise when the guitar is actually being played would have to be dealt with in some other way.

Hm...is your footage actually mp3?

Yup, more or less.

Though, when nothing's being played you colud just lower the volume of that event: split right before first note played, bring down gain, make crosfade...:)

@MikeLV

• The noise threshold must be set as close as possible to the peak of the noise that you're trying to eliminate. That may be different for every clip.
• I agree with @adis-a3097 that applying a noise gate to a lossy source and saving to a lossy delivery file has the potential to create artifacts that might not be created otherwise. I don't know how serious this is, because...
• like @rraud my ears have been worn by decades of crashing cymbals at exactly ear level as well as the drone of enterprise scale computer equipment.
• The noise gate is not my favorite fX even though it seems to do a good job in this case.
• In my day-to-day work I'm more likely to use a volume envelope in areas like this and ease the envelope up as the music starts. That's because I'm more of an archivist than a creator and the noise of the amps and the room were part of the original sound that I might be reluctant to change. After all, if you're going to use technology from the 1930s to amplify your instrument, you should expect to get 1930s noise levels.
• I'm not personally put off by 1930s technology, except that it's getting harder and harder to find a tube tester in the local Thrifty drug store or to find a local Thrifty drug store for that matter.

No, the footage audio is AC-3 as it's from AVCHD video.

Yes. a noise gate/expander is basically for when nothing is being played. Noise reduction software attenuates unwanted noise throughout the file, based on a 'noise print'', which in this case would be the section prior to the music. Some of the newer NR apps. like iZ's RX, has AI options.

I follow what you're saying @john_dennis The noise gate will come in more handy actually when the guitarist is teaching because there are longer periods of silence while he is talking and playing intermittently. But it's helpful here too.

The amount of hiss and other sounds I hear while the guitar are being played solo shouldn't be there; it should be a clean sound, but it's not the end of the world either as you do have to raise the volume pretty high to hear those noises.

'Ehh? What's that ya' say?

I tried the Era4 noise removal plugin from Accusonus and turned the setting up to 100%. (I use this plugin to clean up noisy audio for film).

Izotope RX is on sale. With your type of work, I would jump on it.
