User HRTF Selection for 3D Auditory Mixed Reality

We introduce a novel approach for personalisation of an efficient 3D binaural rendering system designed for mobile, auditory mixed reality use cases. A head-related transfer function (HRTF) ranking method is outlined for users of real-time, interactive sound and music applications. Twenty participants tested the approach and its impact on their capacity to locate a continuous musical sound rendered in varying 3D positions. Analysis of HRTF rankings across three separate sessions reveal encouraging levels of reliability amongst some participants. Patterns of interaction show a significant benefit to horizontal precision that results from the selection process. In contrast, length of system exposure (rather than HRTF preference) demonstrates a significant degree of improvement to aspects of vertical perception and overall speed of response, with no detriment to horizontal accuracy. These findings provide an initial basis from which to consider priorities in the design of audio-only immersive applications and accompanying methods for effective user controlled personalisation

REAL-TIME PHYSICAL MODEL FOR SYNTHESIS OF SWORD SWING SOUNDS

Sword sounds are synthesised by physical models in real- time. A number of compact sound sources are used along the length of the sword which replicate the swoosh sound when swung through the air. Listening tests are carried out which reveal a model with reduced physics is perceived as more authentic. The model is further developed to be controlled by a Wii Controller and successfully extended to include sounds of a baseball bat and golf club

Faddeev eigenfunctions for two-dimensional Schrodinger operators via the Moutard transformation

We demonstrate how the Moutard transformation of two-dimensional Schrodinger operators acts on the Faddeev eigenfunctions on the zero energy level and present some explicitly computed examples of such eigenfunctions for smooth fast decaying potentials of operators with non-trivial kernel and for deformed potentials which correspond to blowing up solutions of the Novikov-Veselov equation.Comment: 11 pages, final remarks are adde
