The Matrix Array is a new type of sound system built around precise, software-defined control of sound in three dimensions - grounded in physics and implemented through a combination of custom hardware and purpose-built software. HOLOPLOT deployed Matrix Arrays in various venues, including the world’s most advanced entertainment venue - the Sphere in Las Vegas (currently also the world's largest audio installation in entertainment). More recently, the X2 was introduced: a smaller form factor aimed at speech intelligibility applications.
Systems at that scale demand engineering across every layer of the stack. Each loudspeaker runs distributed DSP processing onboard, coordinated by on-premises Kubernetes clusters that manage hundreds of devices simultaneously, with cloud services handling remote monitoring and configuration on top, all configured by CAD-like planning software on the desktop. The teams working on this span embedded Linux, Go backend services, Vue/TypeScript web applications, C++/Rust desktop software, and audio plugins across VST, AU, and AAX formats.
