Deej
Deej is a hardware-to-software bridge and system audio manager written in Go that maps physical Arduino sliders to volume levels on Windows and Linux. It functions as a cross-platform audio mixer that allows for the control of master volume, microphone levels, and individual application audio through an external hardware interface.
The project distinguishes itself by providing a configuration-driven mapping system that binds software processes and hardware audio devices to specific physical sliders. It includes logic for slider direction inversion to correct for reversed hardware wiring and supports runtime configuration reloading to update assignments without restarting the background service.
The software covers broad audio management capabilities, including the ability to group multiple software applications under a single control channel and the collective volume adjustment of all unmapped applications. It handles serial-based hardware communication to transfer data from a controller to the computer via a USB connection.
