Helped building 100 hand-held convolver for the 20th anniversary of the Red Bull Music Academy.
Designed and tested the hard/software of a prototype that delivers directional haptic cues to your hand to augment VR.
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.
A mixed, array-based speaker system, where traditional LSFI beamforming and path estimation are simultaneously employed in their respective comfortable frequency range.
A method of generating musical waveforms which relies on sampling a variable polygon in polar space with a rotating phasor.
Interactive AV installation for ZHDK's Immersive Lab installation, featuring 360 deg projection, multi-user interaction and 16 channel spatialisation.
M4L implementation for interfacing the SoundScapeRenderer (http://spatialaudio.net/ssr/) network adaptor.
Investigated the perceived coloration of a synthesized point source presented by stereophony and Wave Field Synthesis using between 14 and 3584 speakers.
