Well.. I seem to remember something like that too. However I haven't got -af 
in my manual (latest pre1 iirc).

If you are using mplayer from sources you could play around with the source 
code of that libao2/pl_volnorm.c. First create file .developer into the 
source root and play around :) Changing AVG to 2? Might not have any effect. 
At least the code looks more complex :) I don't understand it well enough to 
change or add something.
