The paper proposes an enhancement to sound field
reconstruction, which improves spatial perception and
widens the sweet spot size of the 5.1-multichannel
system. Instead of radiating sound directly as in the
original setup, a switch was designed to separate the
direct and diffuse sound fields. The direct field was
radiated normally, and the diffuse field was scattered
with a loudspeaker / diffuser pair.
