Which key milestone in format evolution decoupled sound sources from fixed speaker locations?

Answer

Object-Based Rendering

The progression toward modern immersive audio involved several prerequisite steps, including establishing multichannel formats and developing the understanding of height. However, the computational breakthrough that truly defined the current era was Object-Based Rendering. This methodology fundamentally changed the relationship between audio content and playback hardware by treating a sound element not as something locked to Speaker Channel 7, but as an object assigned dynamic three-dimensional coordinates. This computational liberation of the sound source from the physical speaker location is what allows for dynamic movement within the mix and ensures the mix is adaptable, or scalable, to various speaker counts upon playback.
