MAGIX Audio Cleaning Lab
I don't have this program but after a quick look, I'm guessing if you hit the edit button you may find normalize either in the preset menu or in your Tools menu.
I noticed you mentioned, "raising the volume with magix...".
If your trying to raise the volume look for a "Amplify" type preset.
I use Audacity, if I was trying to increase volume I would probably choose it's "Amplify" effect over "Normalize".
