Hi Mario,
A simple and effective video editor is VideoPad by NCH which is free for non commercial use.
Any video imported will be placed on the video track and the audio extracted and placed on the audio track.
The audio can then be un-linked from the video with a right click command, then the audio can be split cut moved etc and effects added if needed.
