this was to confirm that I had not made any mistake in trying it because 
I had received the same result (with audio distortion) in my own 2-pass 
commandline, as I had seen it in a single-pass ffmpeg action.
Now I come to the conclusion, that it is NOT ffmpeg causing this 
distortion, but the VLC-player after I had a clear sound when playing it 
back with mplayer.
So, thank you all, I have learned a lot and I found a lot of the 
explanation of my former experiences confirmed in this article:

(Thank you Gabri)

But the issue is no longer an ffmpeg issue.

Thank you all one more time.

with kind regards
