Yes, I understand that gain is gain, but he has to decide how much
gain to apply.  If he's previously done that in terms of a pre-gain
peak level, but now wants to bring RMS levels to a certain point,
he surely has to find out what the file's RMS levels are first
then decide how much to modify it by?
