Default Roll back on normalization

If I normalize a track with 500 clips,
can I delete the gain on each clip in one operation later ?

I want to point out that Normalization is destructive editing, in that it is not like a filter that you can turn on and off. It is one of the reasons that I do not like using it except in certain situations and unless you fully understand how to use it. You would have to use Undo until you were to the point before you added Normalize.

Ah ! Normalization is destructive ?
Can you explain ?
Is not it just a variation of gain (level) ?

Edit :
I see an "old" post from Anton: here
"rest assured, the undo function of normalized clips is a high priority on my list
and where there is an Anton, there is a way :)"

Is this undo function in progress ?

Marc

I have not been successful yet

rule1: never use the normalize track tool, it makes a mess, only use the normalize clip tool and do one clip at a time

I can then view the whole timeline with a larger than normal track height and I can right away see if any clip has a different waveform height, it sticks out like a soar thumb

Yes, I agree, the result of 'normalize track' is unpredictable.
But, sometimes it is necessary to apply a normalization on many clips (one clip at a time), and if you want delete all different clip levels, it will be helpful to have the 'undo normalize function' to restore the 0 db level on each clip.

"it sticks out like a a soar thumb"
Everybody can see the sound image in his own way :)

what we need is a normalize filter and one similar to soundforge where RMS is employed to prevent clipping of high spikes

I requested several times

Yes, it's more easy to delete a filter audio on several clips.

There are basically only 2 reasons to use Normalize: maximizing volume or matching volume. Normalizing is no different from moving a volume knob or fader. The entire signal changes by the same fixed amount, up or down. There is no change in dynamic range. Our Normalize (to Peak) scans the entire signal to find the loudest peak, then adjusts each sample accordingly.

It is a destructive process. Performing any digital processing to a file is going to change it. If you apply normalize to a clip the only way to go back to where you were is to use Undo until you are before the Normalize point. You can check this by trying to get your audio back to the original amount after normalize by trying to add a "counter" normalize. You won't be able to get back to the original.

Do not confuse Normalize with Compression.

Normalize (RMS) often referred to as Loudness is coming. However it also has to used with caution.

RMS volume detection is not really like human hearing. We perceive different frequencies at different volumes. If you want to see how this works find a Fletcher–Munson curve. Basically anything between 1000-6000Hz sounds louder to us. And that leads to the whole Loudness discussion. We currently have the Loudness meter but actually being able to edit it is on the roadmap of version 8.

Well, if Edius Normalize would work like my SoundForge that would be cool.

For tough VO's or live music, I render a WAV and place in SoundForge. I click Normalize and click on a box that let's me do 3 different things:: normalize peak value to 0 db, do nothing, or use dynamic compression. There's also many other settings.

So I usually Normalize with some dynamic compression.

That would be great to have in Edius.
