Tegeler Audio Manufaktur released Raumzeitmaschine, a hardware tube reverb unit that can be controlled by plug-in (VST, AU & AAX).
The space-time machine creates a spatial sound that sounds very natural, transparent and clear on the one hand, but also has a nice sound on its own on the other hand.
This is achieved through the unique combination of digital and analog components. There is of course a processor that calculates the reverb. This is enriched by the typical analog sound of our devices.
