Biography: Callum Eaton is a MSc by Research student with the Applied Psychoacoustics Lab at the University of Huddersfield. He graduated in 2018 with a 1st class honours degree in Music Technology and Audio Systems. His current research is investigating auditory immersion in virtual reality and its link to positive user experiences.
Project Title: Quantifying Factors of Immersion in Virtual Reality
Project Summary: The current research project is looking to quantify how significant the impact of height reproduction is to the perception of auditory immersion in virtual reality, and aims to compare a number of common speaker arrangements to determine which is perceived to be the most immersive.

Project title: Perception of Room Acoustics in Virtual/Augmented Reality in the Context of 6 Degree of Freedom
Project summary: This project aims to advance the understanding of how different auditory spatial attributes are perceived in a 6 degrees-of-freedom (6DOF) context where a person can freely move in a room. From a series of subjective experiments both in situ and in lab, a new psychoacoustic model for spatial perception in an enclosed space will be developed. The model will be used for rendering 6DOF immersive audio in VR/AR applications.

Biography: Andrew Parker graduated with a First Class (Hons) Bsc in Music Technology & Audio Systems from the University of Huddersfield. He is currently pursuing a PhD at the APL. This research is focused on identifying and modelling perceptual features of music signals such as ‘punch’ and ‘clarity’, with the goal of developing systems that can objectively measure and manipulate these features.
Project title: Towards a framework for the objective measurement of perceptual audio attributes
Project summary: A real-time system for the objective measurement of perceived ‘punch’ in a music signal has been developed based on previous work. The system’s output shows ‘strong’ correlation with perceptual scores obtained through subjective listening test, with Pearson and Spearman coefficients r=0.840 (p<0.001) and rho=0.937 (p<0.001) respectively. Further validation of the system is planned with subjective data gained from a large scale listening test. The current research focus is ‘clarity’ and defining a perceptually motivated model of it, so that it can be measured objectively.
Biography: Nikita is currently undertaking a MSc by Research Degree in Engineering at the University of Huddersfield . She is a former BSc student in Music Technology and Audio Systems and a former research assistant and web developer at Fraunhofer IIS, Germany. Her skills in web development and interest in binaural audio has lead to developments such as MARRS for the web, a Microphone Array Recording and Reproduction Simulator with virtual loudspeaker rendering and binaural room simulation.
Project Title: Development of a perceptual model for the trade-off between interaural time and level differences for the prediction of auditory image position
Project Summary: For the prediction of a phantom auditory source in stereophonic audio production, it is typical to use a perceptual model for trade-off between “interchannel” time and level differences. Such a model also has been used widely in software tools for designing stereo and surround microphone arrays, including the MARRS app (Microphone Array Recording and Reproduction Simulator) developed by the Applied Psychoacoustics Lab (APL) of the UoH. However, an interchannel-based model is limited to two-channel stereo and not able to accurately predict perceived auditory image position for multichannel arrays, as recently confirmed by Goddard in her final year project (the student named for the proposed project). The ultimate way of predicting image position would be to model the “interaural” time and level difference relationship instead of the interchannel one. This is because the interaural model would not be tied to any specific loudspeaker channel configuration in contrast with the interchannel model. Therefore, the proposed project will conduct a series of listening tests to model the trade-off relationship between interaural time and level differences on perceived auditory position, and apply the result to improve the MARRS tool so that it can be used for designing multichannel microphone configurations.

Biography: Maksims Mironovs is a 3rd year PhD student and a member of the University of Huddersfield’s Applied Psychoacoustics Lab. In 2016 he obtained a First-class degree with Honours in Music Technology and Audio Systems at University of Huddersfield. During his placement, he spent one year at Fraunhofer IIS, where he was involved in multichannel audio research and development of the VST plugins. His outstanding academic achievements led him towards the Vice Chancellor's scholarship to pursue postgraduate research. To date the primary focus of his research has been the human localisation mechanism and analysis of the perceptual effects of 3D audio panning. Additionally, he is interested in mobile application and audio plugin development and is currently working as part time research assistant in the Applied Psychoacoustics Lab.
Project Title: Investigation into the frequency effect on height localisation in multichannel audio systems.
Project Summary: Over the last decade, spatial audio systems have received an increased attention in the cinema, home and car audio. Audio quality of such systems must be of a high standard and be as close to the real environment as possible with sound localisation being one of the main criteria of the realistic spatial audio. The goal of this research is to provide the perceptually based data that can be used in the improvement of localisation accuracy of the current panning methods in spatial audio systems. Additionally, the perceptual mechanism of the vertical panning needs to be theoretically explained. To achieve this goal, subjective and objective investigations into the perceptual mechanism of 3D sound panning will be conducted. These investigations will incorporate practical loudspeaker positions and stimuli, as previous research is limited to the laboratory conditions.
Jade Clarke is currently studying her BSc(Hons) degree in Music Technology and Audio Systems. After her second year of studies she took part in a 12 month internship at Fraunhofer Institute for Integrated Circuits (IIS), where she enhanced her technical knowledge in psychoacoustic research and VST development in relation to binaural 3D audio applications. She is currently completing the final year of her degree and aims to investigate the necessary vertical localisation cues for accurate 3D binaural reproduction.
