Slicing and dicing sound for broadcast. Object-based audio promises immersion, accessibility, personalisation and interactivity, but fears of a format war persist. The audio channel has been the foundation of sound recording and playback since the days of the phonograph. From those mono beginnings the number of channels has risen to produce …

complete mix and effectively doubling the required audio bitrate. An object-based approach enables broadcasters to offer a broader range of options for personalization and consumer choice. Not all audio elements need to be delivered as separate audio objects to reach that goal. Only those audio elements that are beneficial for
Object-Based Audio - Future Reality Lab

You send audio to the concrete speakers and do the mix manually. But with a larger number of speakers and unusual layouts, mixing becomes a challenge. The solution to this problem is object-based audio. With this approach, instead of sending audio to concrete speakers (e.g. left, right), the audio engineer defines audio objects with metadata.

On a broader perspective, we can also see object-based audio being the metadata layer that could help solve the multi-platform challenges of today's media distribution, allowing better audio reproduction for any sort of content in any type of playback device and channel configuration, including binaural virtualization of audio on headphones and spatial audio …

This paper presents a spatial parameters compression approach to decrease the bit rates of spatial parameters for 3D audio. Based on spatial direction filtering and spatial side information clustering, new multi-channel object-based spatial parameters compression approach (MOSPCA) is presented, through which the spatial parameters of intra-frame …
Arbitrarily Shaped Virtual-Object Based Video Compression
https://www2.ece.ohio-state.edu/~zheng/publications/ASVO.pdf
Object based compression techniques are widely believed to have the potential to give the best compression results for a given signal quality. However, true object tracking and extraction is difficult and computationally very expensive. Therefore, an arbitrarily shaped virtual-object compression method is developed.

Scene Based Audio is a set of technologies for 3D audio that is based on Higher Order Ambisonics. HOA is a technology that allows for accurate capturing, efficient delivery, and compelling reproduction of 3D audio sound fields on any device, such as headphones, arbitrary loudspeaker configurations, or soundbars.
