Audio coding via EMD

open access: yesDigital 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 ...

Sinusoidal Analysis-Synthesis of Audio Using Perceptual Criteria

open access: yesEURASIP Journal on Advances in Signal Processing, 2003
This paper presents a new method for the selection of sinusoidal components for use in compact representations of narrowband audio. The method consists of ranking and selecting the most perceptually relevant sinusoids.

A Novel Combined System of Direction Estimation and Sound Zooming of Multiple Speakers [PDF]

open access: yes, 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.

Modelling Timbral Hardness

open access: yesApplied Sciences, 2019
Hardness is the most commonly searched timbral attribute within freesound.org, a commonly used online sound effect repository. A perceptual model of hardness was developed to enable the automatic generation of metadata to facilitate hardness-based ...

Distortion-Free 1-Bit PWM Coding for Digital Audio Signals

open access: yesEURASIP Journal on Advances in Signal Processing, 2007
Although uniformly sampled pulse width modulation (UPWM) represents a very efficient digital audio coding scheme for digital-to-analog conversion and full-digital amplification, it suffers from strong harmonic distortions, as opposed to benign non ...

Deep convolutional neural networks for double compressed AMR audio detection

open access: yesIET Signal Processing, 2021
Detection of double compressed (DC) adaptive multi‐rate (AMR) audio recordings is a challenging audio forensic problem and has received great attention in recent years. Here, the authors propose to use convolutional neural networks (CNN) for DC AMR audio

Preferences of Pediatric Patients and Their Caregivers for Chemotherapy‐Induced Nausea and Vomiting Control Endpoints: A Mixed Methods Study

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Purpose Although not always achieved, complete chemotherapy‐induced nausea and vomiting (CINV) control is the conventional goal of CINV prophylaxis. In this two‐center, mixed‐methods study, we sought to understand the preferences of adolescent patients and family caregivers for CINV control endpoints.

Progressive Syntax-Rich Coding of Multichannel Audio Sources

open access: yesEURASIP Journal on Advances in Signal Processing, 2003
Being able to transmit the audio bitstream progressively is a highly desirable property for network transmission. MPEG- version audio supports fine grain bit rate scalability in the generic audio coder (GAC).

Multiresolution Source/Filter Model for Low Bitrate Coding of Spot Microphone Signals

open access: yesEURASIP Journal on Audio, Speech, and Music Processing, 2008
A multiresolution source/filter model for coding of audio source signals (spot recordings) is proposed. Spot recordings are a subset of the multimicrophone recordings of a music performance, before the mixing process is applied for producing the final ...

On the Consumption of Multimedia Content Using Mobile Devices: a Year to Year User Case Study

open access: yesArchives of Acoustics, 2020
In the early days, consumption of multimedia content related with audio signals was only possible in a stationary manner. The music player was located at home, with a necessary physical drive.
