KLANG:technologies is a German audio company based in Aachen, founded in 2014 as a spin-off of the Institute for Technical Acoustics at RWTH Aachen University by Pascal Dietrich, Benedikt Krechel, Roman Scharrer, and Robin Müller. The company specializes in immersive 3D in-ear monitor mixing, using psychoacoustic binaural processing to position sounds anywhere around the listener's head — including above and below the horizontal plane — rather than collapsing them into the traditional left-right stereo image inside the head.

Its product line is built around immersive personal monitoring for live performance, broadcast, theatre, and houses of worship. Core hardware includes the KLANG:fabrik rack-mount processor, the KLANG:vokal in-ear mixing processor with Dante and MADI connectivity, and the KLANG:kontroller hardware surface for adjusting personal mixes. The ecosystem also extends to Dante headphone amplifiers and the KLANG:quelle XDM for audio routing, with control available via a free app across desktop and mobile platforms.

KLANG was acquired by Audiotonix in December 2018 and operates alongside sister brands including DiGiCo, Allen & Heath, Calrec, and Solid State Logic. Integration with DiGiCo consoles is a notable part of its workflow, allowing immersive monitor mixes to be driven directly from a front-of-house or monitor desk.

Klang has 63 products cataloged on Equipboard, including Kontakt Instrument, Virtual Instrument, and Mixers. Most Klang products sit on the budget-friendly end of the spectrum.
