What is the most affective way of stopping clipping
while keeping noise diffrences from track to track in
an album?

What is the overall best frontend for MPC (EAC doesn't
seem to work for me).

I think replaygain can be used just as a clipping preventer too, not doing volume normalization.



You can use MPC Batch Encoder

or MuseDrop

MuseDrop is easier to use. MPC Batch Encoder makes easier creating huge encoding jobs to work overnight.
