Projects

HapticWave
HapticWave

Designed and tested the hard/software of a prototype that delivers directional haptic cues to your hand to augment VR.

Sound Field Analysis Toolbox
Sound Field Analysis Toolbox

The sound_field_analysis toolbox is a Python port of the SOFiA toolbox for Matlab. It allows you to analyze, visualize and process sound field data recorded by spherical microphone arrays.

Multiband Beamforming for Transaural Audio
Multiband Beamforming for Transaural Audio

A mixed, array-based speaker system, where traditional LSFI beamforming and path estimation are simultaneously employed in their respective comfortable frequency range.

Continuous Order Polygon Waveform Synthesis
Continuous Order Polygon Waveform Synthesis

A method of generating musical waveforms which relies on sampling a variable polygon in polar space with a rotating phasor.

SHFT
SHFT

Interactive AV installation for ZHDK's Immersive Lab installation, featuring 360 deg projection, multi-user interaction and 16 channel spatialisation.

SSR_remote
SSR_remote

M4L implementation for interfacing the SoundScapeRenderer (http://spatialaudio.net/ssr/) network adaptor.

Coloration in Wave Field Synthesis
Coloration in Wave Field Synthesis

Investigated the perceived coloration of a synthesized point source presented by stereophony and Wave Field Synthesis using between 14 and 3584 speakers.
