Research activities

 Sound field analysis/synthesis for acoustic virtual reality
Our laboratory is developing technologies that provide complete immersive experiences using state-of-the-art acoustic signal processing. Most of the existing spatial audio technologies are based on stereo/surround technology. They are effective if listeners are in so-called sweet spot in which listener perceive sound images at pre-defined locations.
In contrast to those existing solutions, we are developing array signal processing technology which reproduces desired sound fields physically. Sound Field Analysis/Synthesis reproduces acoustic pressure field and provides depth-wise control of sound images on top of wide listening area, thereby providing unrivaled quality of immersion for VR.
