Friday Tips: The Air Machine — PreSonus Blog:

Boosting the highs a bit is a time-honored mixing and mastering technique. You don’t want to overdo it, but a little brightness can give a song a lift, increase vocal intelligibility, articulate instruments better, and add some welcome “ear candy.” If you look at the spectral energy of a lot of hit records going back decades, you’ll often find a few extra dB of boost in the 7 to 10 kHz range, to add some “air” and sweetness.

So just boost the EQ a little bit, right? Well, that’s one option…but we can do better. The Air Machine FX Chain (Fig. 1) is equally at home on individual tracks in the Song page (try it judiciously on drums, drum room mics, acoustic guitar, piano, vocals, etc.), or on finished mixes in the Project page. And yes, there’s a download at the end so you don’t even have to create this yourself.
