Hello to everyone, this is my first post here. I have been reading about mastering lately, bought Bob Katz's Mastering Audio-The art and the science and I really find it exciting! Now, maybe my question has been asked a thousand times here and maybe you are too tired of hearing it but I couldn't help it, sorry! The thing is, lately I have been importing tracks from commercial audio cd's into Wavelab 5 to see and visually as well their waveforms. What I have found out is that in most commercial cd's the chorus part looks something like this: http://dl2.rapidshare.de/files/1854578/18897716/how_do_they.JPG The verse's part breathes a bit more but the chorus parts's waveform is almost squashed and it seems as it has no dynamics at all. And maybe it doesn't! But even if it is that way when you listen to it does not sound squashed or overcompressed or anything. In fact it sounds pretty natural. And now the burning question: How do they do it? Thanx in advance for any answer!
