Your requirements are such that the only solution is to mix the audio
for each participant individually. This is a rather expensive operation
and not supported in either of the Asterisk conference applications,
AFAIK.

I can only think of one way of doing that: give each member their own
conference and bridge one leg of that conference into the main
conference. How to accomplish that is a bit beyond me though, but
perhaps others can help.

All the mixing is likely to cause a strain on your hardware, and the
sound quality could suffer.
