[MdG_NL] “What does normalisation exactly do for me? Is it working on a track, on a scene, on a region, or on something else?”
It works on an event basis. It simply takes the LOUDEST point in the audio and adjusts that to the level specified. Therefore, if an event has one loud blip, THAT is what will be used as the loudest point. So if you normalize several clips, they could all still have many different sound levels.
[MdG_NL] “What does it do? Is it adjusting the complete area (see above) to a level so the “average” is on a certain level, or does it something else?”
If you use Sound Forge to normalize, it can normalize based on RMS values.
[MdG_NL] “During interviews I’m fighting with the audio level all the time (using an envelope for that). It’s a hard battle. Can this tool help me winning the battle?”
You might want to try adding a compressor effect instead. That should help even out the levels.
