Air-G Audio is an independent project creating free VST3 plugins with custom analog-style interfaces, built on the open-source DSP algorithms of Airwindows (Chris Johnson). Each plugin builds on one or more of Chris's respected algorithms, pairing them with a full graphical interface: meters, frequency displays, presets, M/S processing, and workflow controls designed for real mixing sessions.
The goal is simple. Air-G gives a visual, hands-on face to DSP that many engineers already trust but that traditionally runs without a GUI. Every plugin credits the original Airwindows algorithms it's based on and includes its MIT license. All plugins are free (pay-what-you-want), available for Windows, Linux, and macOS.
If you find these tools useful, please consider supporting Chris Johnson directly. His work is the foundation everything here is built on.

Fantastic implementation. The rating would have been 5 stars but experienced a bug with the GUI resetting to original size anytime plugin window is closed and reopened (resizing the GUI is not persistent). I believe this can be fixed in a future update, asides from this, this is a lovely implementation.

It is an interesting delay but it seems that certain freq values will make the delay stop making sound.. Once it stops making a sound it can be a challenge to get it to start echoing again. I didn't go back to the original to see if it is a bug or if it is the way the original was working but maybe there is a better max value for freq. I love the graphics other than that.

Reverbs are certainly a strong point for air windows and to have alot of them in one spot is amazing. I was trying out cyber city that may have been hiding in my index with the 100s of reverbs that I have and it was amazing and this made it easy to find. The plates sound nice and they are a favorite of mine for air windows. Would have been good if it didn't have to be uploaded to drive c.

I had the chance to try out some of these beforehand and must say I'm very content with them! Easy to use and very lightweight.
