Highlight all the audio clips you want to match volume on. Right-click the chosen clips on your audio track. Choose "Switches" from the drop-down menu then select the "Normalize" switch.

As has been said, use a limiter on the audio output bus. VEGAS comes with a usable limiter, eFX_Limiter.

Or, select the first audio clip on the timeline, right-click, press N to select all audio tracks after the cursor and lower all the selected audio outputs. Just repeat for all audio tracks.

Or you could simply reduce the output using the Master Bus slider.

Out of curiosity, why don't you want to normalise your tracks?

Amivideotek  says he doesn't want to normalise his tracks. I wonder, why not?

It's the correct way to do it.

Normalizing won't prevent clipping when you have two or more tracks of audio. If all the tracks are normalized, you'll probably get clipping when you add up the two or more tracks of audio. Just because track 1 is at -1 db and track 2 is at -1 db, for example, doesn't mean you get -1 db out the master bus. You'll still get clipping.

Agreed. My main activity is music making using Cubase so I know that audio output is the sum of the parts, as it were. But normalising all the clips on a track will help if there is a limiter on the output bus. Or if you just turn down the output slider.

I always normalise and use a limiter on the output bus(es). If there are any problems with audio spikes in some clips (eg, people whispering, then someone slams a door), it's time to roll up one's sleeves and address each clip individually, even to the extent of editing the audio in an external editor.

Lowering Audio Bus Track, eFX Limiter and Master Bus lower both the track with the song and the track with the various audio events.
I don't want this, the Track with the song has to stay as it is and the Track with the various audio events have to be adjusted.

@fr0sty @Googly-Smythe

When I select all audio events on the track with the various audio events and use Switches>Normalise to select them, all sounds are maximized below the level of distortion. I am now required to reduce the entire track volume.
But because the background and foreground sounds are maximized just below the level of distortion, I no longer hear any difference in the foreground and background sounds.

Is there an automatic method that checks each audio event separately along for distortion together with the track with the song and if necessary the volume of the audio events is lowered to just below this level?

You don't want to normalise.

You don't want to use a limiter.

You don't want to adjust the track or bus levels.

You don't want to adjust the clip levels.

I'm going to go out on a limb here and say "No." The only way I see that this can be done is for a plugin to be told the reference track, the track to be adjusted, analyse the selected tracks, and then perform it's magic.

The only solution I can think of that may remotely do the job is a VST by Izotope: Neutron or Ozone, each of which cost more than VEGAS. I've never used them, but they have some AI functions that may help.

I'd be interested if any one can come with a solution for this problem, that doesn't require the use of expensive 3rd party tools.

@Googly-Smythe Yes, it is possible. Now I've done it manually, but I'll look around for the future when the same problem happens to me. I always look for an easier way.

There are a number of different ways it can be done with Vegas. If you have multiple clips recorded at different levels, normalizing can match the maximum peaks in the various clips to one another. Works well when the relative levels throughout each clip are consistent, but they just don't match one another. It's a good 1st step to match up separately recorded clips. A variation if you have a long clip with some loud parts and some soft parts is to split it into sections and do the same thing.

If you want to get a little deeper into the weeds on that, you could also take loudness readings for the various audio clips and manipulate the loudness with compression or expansion to force them into a closer match while holding peak levels constant. I often do that on stage shows featuring multiple performers of different styles and/or dynamics.

A more automatic and natural sounding way to do it is with either variable compression or brick-wall limiting compression. One natural sounding tool I often use is the Vegas Wave Hammer fx Volume Maximizer threshhold control to bring peaks down 3 to 6 db which can lift non-peak parts of the clip by the same amount depending on how you set the output level. If more is needed, I follow that with maybe 5:1 broadband compression.

Some audio tracks are so badly captured that none of that works well enough. Happens allot when performers wander away from the mic while talking or singing. In those cases I go manual with volume envelopes on tracks and lots of breakpoints. Sometimes its so bad that the 6db range of a volume envelope is inadequate. In which case I create a track envelope for the the track compressor's input or output gain which have 25db ranges... that's a pretty extreme correction range and is only practical with very low self-noise recordings.
