SCALABLE AUDIO CODING USING WATERMARKING [PDF]
2013 IEEE International Conference on Multimedia and Expo (ICME), 2013 A scalable audio coding method is proposed using a technique, Quantization Index Modulation, borrowed from watermarking. Some of the information of each layer output is embedded (watermarked) in the previous layer.

Bit rates in audio source coding [PDF]
, 1992 The goal is to introduce and solve the audio coding optimization problem. Psychoacoustic results such as masking and excitation pattern models are combined with results from rate distortion theory to formulate the audio coding optimization problem.

High Quality Audio Coding with Mdctnet
ICASSP 2023 - 2023 IEEE International Conference on Acoustics, Speech and Signal Processing (ICASSP), 2023 We propose a neural audio generative model, MDCTNet, operating in the perceptually weighted domain of an adaptive modified discrete cosine transform (MDCT). The architecture of the model captures correlations in both time and frequency directions with recurrent layers (RNNs).

A Novel Combined System of Direction Estimation and Sound Zooming of Multiple Speakers [PDF]
, 2015 This article presents a new system for estimation the direction of multiple speakers and zooming the sound of one of them at a time. The proposed system is a combination of two levels; namely, sound source direction estimation, and acoustic zooming.

Coding overcomplete representations of audio using the MCLT [PDF]
, 2008 We propose a system for audio coding using the modulated complex lapped transform (MCLT). In general, it is difficult to encode signals using overcomplete representations without avoiding a penalty in rate-distortion performance.

Digital Signal Processing, 2020 Abstract In this paper an audio coding scheme based on the empirical mode decomposition in association with a psychoacoustic model is presented. The principle of the method consists in breaking down adaptively the audio signal into intrinsic oscillatory components, called Intrinsic Mode Functions (IMFs), that are fully described by their local ...

Studi dan Analisis Kinerja Mpeg Surround pada Bitrate 256 – 400 Kbps
Jurnal Nasional Teknik Elektro, 2016 MPEG Surround is one of the spatial audio codings that popularly used. MPEG Surround is generally used at a low bitrate such as 64, 96 and 160 kbps. MPEG Surround can be used at high bitrates, but the audio quality produced in the bitrate is not yet ...
