Which format attempted to bridge the gap by incorporating a distinct height layer within a channel-based framework?

Answer

Auro-3D

Before the full object-based revolution became the mainstream standard, certain technologies sought to introduce verticality while still relying on defined speaker mapping, which is characteristic of channel-based structures. Auro-3D is specifically cited as an example of a system that provided an immersive experience by adding a dedicated height layer positioned above the traditional surround plane. This was achieved through specific, predefined speaker arrangements designed to create that vertical immersion. While this approach represented an important step in acknowledging the vertical axis of sound, it remained intrinsically linked to specific speaker configurations, contrasting with the flexible scalability offered by later object-based models.
