This article presents the whole loudness and metering issue from the very basics. I've found using the meters in iZotope's InSight to be indispensable to me while editing and pre-mixing projects in my small home studio, before either delivering to clients, or going to a larger studio that's going to cost me (or my clients) much more money. I'm looking forward to part 2. Thanks to Designing Sound for linking to this article.
