How to use the free Air Shelf EQ from Bertom Audio in mastering?
The Air Shelf EQ from Bertom Audio has a lot of useful functions to use for mastering.
The first dial on the plugin is really simple – it amplifies high frequencies, but you can also attenuate them too!
This is great because in many cases with mastering vocals or instruments that have come out sounding over-saturated and distorted after recording, sometimes lowering some highs will help get back clarity without losing volume in other ranges.
What is the difference between Boost and Tame?
Boost works on low frequencies while taming high frequencies. From our own experimentation, we found that there are two ways in which one can alter sound:
By amplifying it or weakening it.
The Bertom Freq Analyzer has a knob called “boost” to amplify certain frequency levels of your music – but not all!
If you want more bass for example, then try pushing up the boost button; if you’re looking for some clarity at higher notes (perhaps because everything else sounds muddy) go ahead and push down on the tame dial instead.
