Preserving audio scenes in the form of audio objects has become common in recent years.
Object-based audio techniques provide more flexibility for personalized rendering as well as …

Scene-based Audio uses a sound-field technology called “Higher Order Ambisonics”(HOA)
to create holistic descriptions of both live-captured and artistically-created sound scenes that …

Rendering spatial sound scenes via audio objects has become popular in recent years,
since it can provide more flexibility for different auditory scenarios, such as 3D movies …

This paper presents a compression technique to improve the quality of three-dimensional
(3D) audio produced by multiple loudspeaker channels or by headphone. The approach is …

Abstract Three-dimensional (3D) audio technologies are booming with the success of 3D
video technology. The surge in audio channels makes its huge data unacceptable for …

There are provided decoding and encoding methods for encoding and decoding of
multichannel audio content for playback on a speaker configuration with N channels. The …

An encoding system (400) encodes an N-channel audio signal (X), wherein N≥ 3, as a
single-channel downmix signal (Y) together with dry and wet upmix parameters (C, P). In a …

In this paper, we propose a novel compression method that can efficiently compress a vector
quantization (VQ) index table. Before compressing the VQ index table, the method sorts all …

In multichannel spatial audio coding (SAC), the accurate representations of virtual sounds
and the efficient compressions of spatial parameters are the key to perfect reproduction of …
