For the home recorders out there, here's a pretty good article on compression/limiting. The main thing that sets this article apart: it has audio examples. As a ranty aside: why is this article one of the very few with audio examples? There's no shortage of tutorials on the net for recording, but almost none of them have any audio with them and are basically worthless without that.
A while back I had an idea about starting a recording website where any tips you gave had to be backed up by audio examples, money where your mouth is style. But then I had other things to do I guess.
