Using Qt to Create a Cross Target Audio Holoplot 3D Audio Wall
summary
Holoplot demonstrates a wall of beamforming speakers built with Qt and KDAB software control, claiming location-specific sound spots and room emulation. The demo uses an array of 1000+ speakers organized in module sizes 4 14 40 400, driven by an embedded SoC backend and desktop setup tool that imports a 3D room model. A tablet control and mixer runs as a tablet UI on iOS and Android and the system successfully produced distinct 3D sound sources in a damped dome.
