Oh! when at all the Normalize effect needs to be used?

Sorry, I missed that. Normalizing is amplifying to a certain level. So you need it for example to get a too soft recording louder (if the peaks allow, or with clipping if there are too high peaks. But clipping doesn't sound nice).

Normalizing is amplifying the recording so that the biggest waveform is at a certain level. So if you had a very quiet recording with one loud click that causes a spike in the wave form, normalizing would adjust the volume such that that one spike would be at the level you specify (X dB under maximum/clipping).

Amplifying is... amplifying the recording a specified amount, regardless of peaks or wave forms.

I amplify instead of normalize because it tells me more about what the final volume of the recording will be. If ReplayGain or MP3Gain says "adjust the volume by 3.0 dB", I know if I amplify, I can do it by 3.0 dB. Normalize doesn't tell me how much it's changing the volume, other than that the peak wave form will be within X dB of clipping.

In the ReplayGain plug-in, I think calling it "normalize" is the wrong term. What it's doing is actually amplifying to get you to the desired level, just like using Effect/Amplify would.

That's the question.

I don't know if anything like this exists. I try to minimize those sounds on reading. If your throat is open, the body will take easily and quietly only the air needed. It is what singer do

It would be called a "De-Breather"

Those who want to remove them use a "Noise Gate", which essentially eliminates (squashes to 0) all samples lower than the given level. It does make for a very weird listening because there is usually room noise under the voice, which is completely gone between phrases. Sounds like somebody turns the mic totally off right after speaking and turns it on again just before speaking. Done well it works. You need a really quiet place to record in, you need to clean the rest of the audio before applying noise gate, and then it just might sound OK... Do keep that in mind.
