  • ASIO sound board
  • IEC Listening room

 


Key figures

 

  • 3 project members
  • Project duration: 3 months

Context

 

The project goal is the enhancement of the ‘embracement effect’ of home cinema sound systems. The aim was to create a sound volume which would ‘submerge’ the listener, thus improving the listening experience.
