[LAU] Tips for mastering?

Hello! In a month or so I'll for the first time in my life attempt to master two smaller EPs (my own music should be added). I've worked up a fairly good skillset with some parts of the mastering (multiband compressing etc) but I need some major help with tips for what I'm trying to accomplish, which is: * I want a similar soundlevel throughout the whole of the EP, eg. I want the songs to be similar in strength even if they are dissimilar in dynamics/type of song. Some songs are naturally more "aggressive" and thus will be a bit stronger, but I want the climaxes in the more easy going songs to be as strong. I realise that most of this will be done through the traditional "just listen and compare", but I'm wondering if there are any other analyzingtools that might ease my work a bit? Like analysing RME for the whole song, will that give a fair indication that can be compared amongst songs? Fatigued ears and the need for alot of small breaks is calculated with, but those difficulties will be pretty testing for me I think with my low patience lol, so anything that makes the process easier is good stuff! Mastering on my own like this probably isn't that good, I know, but I'm looking at it as an opportunity to learn some tricks of the trade. I will be using plugins from linuxDSP together with a few Calf ones and the Foo Limiter, so no Jamin etc. Do you have any general tips for me etc? All tips I can get are greatly appreciated! Thanks in advance, regards,
