Air-G Pulse Mini

Air-G Pulse Mini is part of Air-G Audio, a collection of plugins built on the open source work of Airwindows, Chris Johnson's project that has been releasing high-quality free DSP algorithms for years.

Air-G Pulse Mini is the compact version of Air-G Pulse, with the same program compression engine built on Airwindows' Pressure6, in a reduced vertical interface styled after 500-series rack modules. Every control is there: COMPRESS, PRESSURE, SC HPF, OUTPUT, AUTO GAIN, and the gain reduction VU meters. The difference is purely visual, designed for crowded sessions or those who prefer a smaller footprint.

For a full description of the audio engine and typical uses, see the Air-G Pulse page.

Air-G Audio is a collection of plugins built on the open source code of Airwindows. The project is built around adding a graphical interface that makes the experience more comfortable and visual, along with a few features that expand the possible uses without straying from the original sound. The simplicity and lightness of Chris's code are the starting point and the guide.

Thanks to Chris Johnson for making his work public and accessible. Air-G Audio exists because Airwindows exists. The Airwindows code used in this plugin is published under the MIT License.

Air-G Pulse Mini is free. You can download it without paying anything, following the same open philosophy that runs through all of Chris's work. If the plugin is useful to you in your music, a contribution is always welcome. Chris Johnson's Patreon is also worth knowing about: it's the most direct way to support the Airwindows project and the work that makes plugins like this one possible. patreon.com/airwindows

Available for Windows, Linux and macOS.

*New: Windows & Linux — All VST3, no installer download

***Windows note: the installer is not signed with a paid certificate, so SmartScreen may show a "Windows protected your PC" warning. Click "More info", then "Run anyway" to continue. This is expected and not a problem with the plugin.

***macOS note: the plugin is not signed with an Apple developer certificate, so Gatekeeper may block it on first use. The "Open Anyway" option in System Settings does not work reliably for audio plugins. The correct fix requires Terminal:
1. Open Terminal (Applications > Utilities > Terminal).
2. Type: sudo xattr -rd com.apple.quarantine (leave a space at the end, do not press Enter yet).
3. Open Finder and navigate to your plug-in folder: VST3 plugins are in /Library/Audio/Plug-Ins/VST3/, and AU plugins (for Logic and GarageBand) are in /Library/Audio/Plug-Ins/Components/. Drag the plugin file (the .vst3 or the .component) into the Terminal window. The path fills in automatically.
4. Press Enter and type your admin password when prompted (it will not be visible). Press Enter again.
5. Rescan your plugins in your DAW. The plugin should now appear. If you installed both the VST3 and the AU versions, repeat the process for each file.
