This is going to be pretty broad cause this stuff just confuses me so I wondering, if you guy's could give me some resources to check out so I can understand them a little better. I don't even know how to ask a question so I'll just list it out what I'd like to learn haha:

  • LKFS

  • Leq

  • Weighting Filters

  • Dialnorm

  • Intersample Peaks

Thanks.

Busy day for me right now, but I'll point you to a blog post I did a little while ago that covers some of the basic of loudness metering: http://www.dynamicinterference.com/blog/2012/04/what-the-hell-do-all-these-letters-and-numbers-mean/

It'll get you started at least.

If you want to go hardcore...

This is a great video explaining intersample peaks. While they are talking about the metering in Final Cut, the information is still great.

Some useful and enjoyable reading regarding "Loudness normalisation and permitted maximum level of audio signals"
