Zirkonium
ZKM | Hertz-Lab
Zirkonium is a free macOS toolkit for spatial-audio composition and performance, developed at ZKM | Hertz-Lab Karlsruhe to drive the Klangdom — a 47-loudspeaker dome at the ZKM Kubus. Current version Zirkonium MK3 (since 2015) provides parametric trajectory creation over time, automatic interpolation, event filtering, and real-time rendering on arbitrary 2D or 3D loudspeaker setups. The DSP server is built on Pure Data (libpd) and uses VBAP, Higher-Order Ambisonics (HOA library, CICM), and binau
History & Background
Developed by ZKM | Hertz-Lab (formerly Institute for Music and Acoustics, ZKM Karlsruhe). MK1 (2006) was the first version, followed by MK2 (2012, modular Max/MSP-based architecture), and MK3 (2015 onwards). The Pure Data spatialisation server is open-sourced on GitHub (zkmkarlsruhe/ZirkoniumSpatializationServer).
