The structure of proposed method N-step SAOC. N is the number of audio objects. M is the label of downmix signal, parameters, and residual information in each step. Full size image. In our N-step coding framework, the input of the object ordering module and encoding pair choose module are initial object signals.

Spatial Audio Object Coding (SAOC) is a parametric multiple object coding technique that overcomes these drawbacks. It is designed to transmit a number N of audio objects in an audio signal that comprises K downmix channels, where K . N and K is typically one or two channels. Together with this backward compatible downmix signal, object meta ...

Abstract: Object-based representations of audio content are increasingly. used in entertainment systems to deliver immersive and. personalized experiences. Efficient storage and transmission. of such content can be achieved by joint object coding algorithms. that convey a reduced number of downmix signals.

The spatial audio object coding (SAOC) is an effective meth-od which compresses multiple audio objects and provides flexibility for personalized rendering in interactive services. It divides each frame signal into 28 sub-bands and extracts one set object spatial parameters for each sub-band. Objects can be coded into a downmix signal and a few ...

In late 2014, the ISO/MPEG standardization group made available a new specification, Spatial Audio Object Coding for Dialogue Enhancement (SAOC-DE), which was closely derived from the well-known MPEG-D Spatial Audio Object Coding (SAOC). This paper describes the architecture and features of the new system.
Immersive Audio Delivery Using Joint Object Coding
https://www.aes.org/e-lib/download.cfm/18285.pdf?ID=18285
In a basic joint object coding system, each audio object is reconstructed as a linear combination of the downmix channels within a time/frequency tile. This is shown in the upper path of Fig. 3, where “T/F” indicates a QMF analysis bank. In each time/frequency tile, the coeffi-cients of this linear combination can be represented by

Dolby Digital Plus JOC (Joint Object Coding) The second reference is a technical term that may be found in some Dolby documentation or papers. Joint Object Coding describes the process by which Dolby Digital Plus with Atmos decoders, receiving a legacy 5.1 mix and sideband metadata, are able to reconstruct the original Atmos mix.
