I've been digging through past postings and found a similar question to the one I have, but my diffeence is this: When setting the normalize filter on Nero5.5, why would one use Maximum (which goes up to 99 in the setting) or RMS(root-mean-square) which starts by default at 20. You can raise or lower this one incrementaly, BUT, this still gets a little confusing. Any takers? Much obliged!!
