Goal of this project is to develop a prototype 3D audio reproduction system that can be placed around a (small) touch screen and play back multichannel audio. You will need to consider loudspeaker placement, amplification, mounting options and an analysis of the feasible number of output channels as a function of device capabilities. Furthermore you will need to investigate appropriate sound spatialization or beamforming algorithms. Prototyping target is an ARM platform (most likely Raspberry-Pi) running LINUX.

This project is available as a Bacheror Thesis or TI-Project (mostly related to the development of the platform) and as a Master Thesis in which you will additionally either need to design, prototype, and evaluate applications for the array you have developed or pereptually evaluate the resulting device.
