Air-G Audio has released Air-G Plugins Collection, a free/pay-what-you-want bundle of 18 audio plugins built on open-source DSP algorithms from Airwindows.
Airwindows plugins have been around for a long time, and they have an almost legendary status among us bedroom producers. Chris Johnson’s approach has always been more about sound and speed than shiny interface design.
The only real drawback, depending on how you like to work, is that Airwindows plugins don’t have custom GUIs. They use whatever default interface your DAW gives to GUI-less plugins, which is perfectly usable but not always inspiring when you’re in the middle of a mix.
There is also the relatively recent Airwindows Consolidated plugin that makes the whole package more convenient to use, but it’s still not the standard GUI approach we’re all used to.
That is where Air-G Audio comes in. Developer Gonzalo notified me that he built the collection as an Airwindows user seeking more visual feedback on the tools he uses most.
The important part is that the DSP hasn’t changed. These are still Airwindows algorithms underneath, but they now sit inside custom analog-style interfaces with extra workflow features on top.
Depending on the plugin, Air-G adds handy features like gain reduction meters, frequency response displays, presets, M/S processing, parallel compression controls, DAW tempo sync, sidechain filters, A/B comparison, and visual animations that react to the processing.
It won’t change the sound, but for visual people like myself, those additions can make the same processors feel much easier to understand and use.
The collection covers a pretty broad mixing toolkit. The dynamics section includes four compressors, Pop!, Pulse, Velvet, and Volt, with each one also available in a compact Mini version. Clip combines two clipping modes and includes Delta monitoring, while Dess handles sibilance by looking at waveform shape rather than using a more typical frequency-targeted approach.
For EQ duties, EaseQ is a four-band EQ with wide Bezier curves and an interactive display, while Prism is a six-band graphic EQ with fixed frequencies and draggable nodes. Tape handles full tape emulation with head bump, flutter, three-band EQ, and presets, while Taped offers a more focused saturation approach with M/S processing. Echoes is a varispeed tape delay with tempo sync and a high-pass filter in the feedback loop, and Mods puts Chorus, AutoPan, Tremolo, and Vibrato in one plugin.
Spaces is the reverb of the collection, combining 16 Airwindows K-series reverbs in one interface, with rooms, halls, plates, chambers, and more experimental spaces. It also adds Pre Delay, HPF, and four memory slots for quick comparison.
Every plugin includes a manual in Spanish and English, credits the original Airwindows algorithm, and includes the MIT license. The product page also points users toward Chris Johnson’s Patreon for anyone who wants to support the original Airwindows project directly.
Air-G Plugins Collection is available for Windows, Linux, and macOS. The product page describes the bundle as VST3, while the macOS installation notes also refer to AU components, and the plugins are not signed with paid Windows or Apple developer certificates.
