Object-Based Audio Recording Methods

Document Thumbnail

The new ADM standard enables to define an audio file as object-based audio. Along with many other functionalities, the polar coordinates can be specified for each audio object. An audio scene can therefore be described independently of the reproduction system. This means that an object-based recording can be rendered on a 5.1 system, a binaural system, or any other system. In the case of a binaural system, it also gives the opportunity to interact with the audio content, as a headtracker can be used to follow the movements of the listener’s head and change the binaural rendering accordingly. This paper describes how such an object-based recording can be achieved.
