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 Psychoacoustic-Based Multiple Audio Object Coding Approach via Intra-Object Sparsity

open access: yesApplied Sciences, 2017
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, spatial audio communication and virtual classrooms. To facilitate high-quality

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 ...

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 ...

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).

Perancangan dan Analisis Kinerja Steganography pada MPEG SAOC Menggunakan Improved Spread Spectrum

open access: yesJurnal RESTI (Rekayasa Sistem dan Teknologi Informasi), 2019
Object-based audio technology is important for audio reproduction because of providing the users with an ability to change the audio composition. As a result, MPEG Spatial Audio Object Coding (SAOC) as an international standard for encoding object-based ...

MPEG-4 natural audio coding [PDF]

open access: yesSignal Processing: Image Communication, 2000
MPEG-4 audio represents a new kind of audio coding standard. Unlike its predecessors, MPEG-1 and MPEG-2 high-quality audio coding, and unlike the speech coding standards which have been completed by the ITU-T, it describes not a single or small set of highly efficient compression schemes but a complete toolbox to do everything from low bit-rate speech ...

Health‐Related Quality of Life and Symptom Severity Among Patients With PIK3CA‐Related Overgrowth Spectrum: A Mixed‐Methods Study to Understand Real‐World Experience With Alpelisib Treatment

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Background PIK3CA‐related overgrowth spectrum (PROS) includes several rare overgrowth disorders resulting from somatic gain‐of‐function mutations in PIK3CA. Despite treatment advances, including the recent approval of alpelisib for PROS in the United States, literature detailing the patient experience with PROS is limited.

AMBIQUAL: Towards a Quality Metric for Headphone Rendered Compressed Ambisonic Spatial Audio

open access: yesApplied Sciences, 2020
Spatial audio is essential for creating a sense of immersion in virtual environments. Efficient encoding methods are required to deliver spatial audio over networks without compromising Quality of Service (QoS).
