Release note: extrox "A3.1EF(arch) / 3.1EF.25(debian)"
6 Aug 2026
6 Aug 2026
This release focuses on improving the desktop experience and system stability. Based on MX Linux 25 (Debian) or MX Arch Linux (Arch), extrox 3.1EF.25 / extrox A3.1EF serves as the operating environment for the "Super Headphones Alpha" and "Sound Heaven Alpha" audio filters, which are specialized for music and movie playback. These filters process audio played on the PC in real-time to reshape the sound. Features include Windows-like window fade effects and 3D Alt+Tab transitions powered by Compiz, as well as a function that gathers active windows when the cursor is moved to the top-right corner of the screen. Default window color is cyan. With Emerald Theme Manager, you can choose your favorite color from cyan, violet, pink, and dark gray. This is a conceptual OS designed to meet the expectations of audiophiles by combining a macOS-like user experience with a unique UI aesthetic. The latest snapshot features transparent Start Menu icons, fixes an issue where brightness would dim during live boot, and replaces some artwork. The dock panel hides intelligently. Super Headphones Alpha recommends the Hi-X20, MDR-7506, and HD280 Pro headphones.

Philosophy
This snapshot continues the extrox concept:
“A media-art Linux for breathing.”
The extrox 3EF series is designed as an operating system that delivers the kind of relaxation found in a late-night club or a quiet research lab.
Freja believes that true healing can exist within a gentle sense of excitement — especially through Audio-Filter’s immersive sound experience.
