PurestAir is a universal binary Audio Unit plugin for enhancing treble up near the Nyquist Limit! It specifically
tweaks that sonic area, wherever it is, with special Airwindows algorithms. The idea is to get ‘air band’ boost
without the coloration of a normal equalizer, and in line with the Purest style of plugins it’s done with a really
simple and elegant algorithm.

There’s also an ‘Air Limit’ control, and what this does is kick the previous control down if the energy gets too
high. It’s not properly a de-esser by itself, but it does work to moderate the brightness effect. You can use it
without air-band boost, to function as a tone softener.

PurestAir is really clean and maintains the tone quality of what’s passing through it, adding little color of its
own. Part of the secret to that is the way it operates relative to the Nyquist Limit. What that means is, PurestAir
is a different plugin depending on what sample rate you use. If you’re at 44.1K it’ll have the most obvious effect
as it’ll be working at around 22K. If you’re at 48K, it’ll center on 24K and so on. Still functional at 96K (with
a boost at 48K but some effect in the audio band), probably no longer useful on 192K. Be aware that this isn’t a
normal EQ algorithm and is dependent on your sample rate.

All Airwindows plugins are modular, graphic-less, stripped-down, Audio Unit plugins, for the Mac. They’re all coded
to work on PPC and Intel processors, because there are a lot of perfectly good PPC Macs out there in studios.
They are also all 64 bit- triple binary, i386 / x86_64 / ppc.

Just test it and its very interesting. Yep it gives an high shelf as "Air " but a bit "glassy", the alike low shelf is good too. Not in bad way at all. But we have to be aware of it.
The Limiter is well done too, giving more control when pushing the plug at his own limit.

I love Airwindows plugs, always very well done, and there are pointing some really interesting vue on what kind of tools we need to create, to mix stuff.
