Evaluating a distortion-weighted glimpsing metric for predicting binaural speech intelligibility in rooms (2016)
Journal Article

A distortion-weighted glimpse proportion metric (BiDWGP) for predicting binaural speech intelligibility were evaluated in simulated anechoic and reverberant conditions, with and without a noise masker. The predictive performance of BiDWGP was compare... Read More about Evaluating a distortion-weighted glimpsing metric for predicting binaural speech intelligibility in rooms.

101 mixes : a statistical analysis of mix-variation in a dataset of multi-track music mixes (2015)
Presentation / Conference
Wilson, A., & Fazenda, B. (2015, October). 101 mixes : a statistical analysis of mix-variation in a dataset of multi-track music mixes. Presented at 139th International Convention of the Audio Engineering Society, New York City, New York, USA

The act of mix-engineering is a complex combination of creative and technical processes; analysis is often performed by studying the techniques of a few expert practitioners, qualitatively. We propose to study the actions of a large group of mix-engi... Read More about 101 mixes : a statistical analysis of mix-variation in a dataset of multi-track music mixes.

Perceived audio quality of sounds degraded by non-linear distortions and single-ended assessment using HASQI (2015)
Journal Article
assessment using HASQI. Journal of the Audio Engineering Society, 63(9), 698-712. https://doi.org/10.17743/jaes.2015.0068

For field recordings and user generated content recorded on phones, tablets, and other mobile
devices nonlinear distortions caused by clipping and limiting at pre-amplification stages, and
dynamic range control (DRC) are common causes of poor audio... Read More about Perceived audio quality of sounds degraded by non-linear distortions and single-ended assessment using HASQI.

A glimpse-based approach for predicting binaural intelligibility with single and multiple maskers in anechoic conditions (2015)
Presentation / Conference
Tang, Y., Cooke, M., Fazenda, B., & Cox, T. (2015, September). A glimpse-based approach for predicting binaural intelligibility with single and multiple maskers in anechoic conditions. Presented at Interspeech 2015, Dresden, Germany

A distortion-weighted glimpsing metric developed for estimating monaural speech intelligibility is extended to predict binaural speech intelligibility in noise. Two aspects of binaural listen- ing, the better ear effect and the binaural advantage, ar...

Navigating the mix-space : theoretical and practical level-balancing technique in multitrack music mixtures (2015)
Book Chapter
Wilson, A., & Fazenda, B. (2015). Navigating the mix-space : theoretical and practical level-balancing technique in multitrack music mixtures. In The 12th Sound and Music Computing Conference, Music Technology Research Group, Dept. of Computer Science, Maynooth University, Maynooth, Co. Kildare, Ireland. Sound and Music Computing

The mixing of audio signals has been at the foundation of
audio production since the advent of electrical recording in the 1920’s, yet the mathematical and psychological bases for this activity are relatively under-studied. This paper investigates h...

Perceptual thresholds for the effects of room modes as a function of modal decay (2015)
Journal Article
of modal decay. ˜The œJournal of the Acoustical Society of America (Online), 137(3), 1088-1098. https://doi.org/10.1121/1.4908217

Room modes cause audible artifacts in listening environments. Modal control approaches have
emerged in scientific literature over the years and, often, their performance is measured by criteria
that may be perceptually unfounded. Previous research... Read More about Perceptual thresholds for the effects of room modes as a function of modal decay.

Perception and automatic detection of wind-induced microphone noise (2014)
Journal Article
Jackson, I., Kendrick, P., Cox, T., Fazenda, B., & Li, F. (2014). Perception and automatic detection of wind-induced microphone noise. ˜The œJournal of the Acoustical Society of America (Online), 136(3), 1176-1186. https://doi.org/10.1121/1.4892772

Wind can induce noise on microphones, causing problems for users of hearing aids and for those making recordings outdoors. Perceptual tests in the laboratory and via the Internet were carried out to understand what features of wind noise are importan...

Categorisation of distortion profiles in relation to audio quality (2014)
Presentation / Conference
Wilson, A., & Fazenda, B. (2014, September). Categorisation of distortion profiles in relation to audio quality. Presented at 17th International Conference on Digital Audio Effects (DAFx-14), Erlangen, Germany

Since digital audio is encoded as discrete samples of the audio waveform, much can be said about a recording by the statistical properties of these samples. In this paper, a dataset of CD audio samples is analysed; the probability mass function of ea... Read More about Categorisation of distortion profiles in relation to audio quality.

Automatic detection of microphone handling noise (2014)
Presentation / Conference
Kendrick, P., Cox, T., Li, F., Fazenda, B., & Jackson, I. (2014, May). Automatic detection of microphone handling noise. Presented at 4th International Workshop on Cognitive Information Processing, Copenhagen, Denmark

Microphone handling noise is a common problem with user generated content. It can occur when the operator
inadvertently knocks or brushes a recording device.
Handling noise may be impulsive, where a microphone is
knocked, or a more sustained rubbi... Read More about Automatic detection of microphone handling noise.

Physical and numerical constraints in source modeling for finite difference simulation of room acoustics (2014)
Journal Article

In finite difference time domain simulation of room acoustics, source functions are subject to various constraints. These depend on the way sources are injected into the grid and on the chosen parameters of the numerical scheme being used. This paper...
