AudioBIFS: Describing audio scenes with the MPEG-4 multimedia standard
TLDR
An overview of the AudioBIFS system, part of the Binary Format for Scene Description (BIFS) tool in the MPEG-4 International Standard, and the current state of implementations of the standard are described.Abstract:
We present an overview of the AudioBIFS system, part of the Binary Format for Scene Description (BIFS) tool in the MPEG-4 International Standard. AudioBIFS is the tool that integrates the synthetic and natural sound coding functions in MPEG-4. It allows the flexible construction of soundtracks and sound scenes using compressed sound, sound synthesis, streaming audio, interactive and terminal-dependent presentation, three-dimensional (3-D) spatialization, environmental auralization, and dynamic download of custom signal-processing effects algorithms. MPEG-4 sound scenes are based on a model that is a superset of the model in VRML 2.0, and we describe how MPEG-4 is built upon VRML and the new capabilities provided by MPEG-4. We discuss the use of structured audio orchestra language, the MPEG-4 SAOL, for writing downloadable effects, present an example sound scene built with AudioBIFS, and describe the current state of implementations of the standard.read more

Methods and apparatuses for encoding and decoding object-based audio signals
TL;DR: In this paper, an audio decoding method was proposed to generate a third downmix signal from a first audio signal and another from a second audio signal by combining first object-based side information extracted from the first signal and second object-bounded side information from the second signal.

Signal compression based on models of human perception
TL;DR: It is proposed that fundamental limits in the science can be expressed by the semiquantitative concepts of perceptual entropy and the perceptual distortion-rate function, and current compression technology is examined in that framework.

Auralization-An Overview
TL;DR: Auralization is a term introduced to be used in analogy with visualization to describe rendering audible (imaginary) sound fields as mentioned in this paper, together with new hardware implementations of signal processing routines, it forms the basis of a powerful new technology for room simulation and aural event generation.

Predictive coding of speech signals and subjective error criteria
TL;DR: Improved speech quality is obtained by efficient removal of formant and pitch-related redundant structure of speech before quantizing, and by effective masking of the quantizer noise by the speech signal.
