The figure shows the paths of the “sound rays” as they propagate from a sound
source (red, black and brown balls) to the receiver (blue ball). The DSP
calculates the properties of a reflection sound (time delay and direction) from the
paths of the sound rays. The simulation computations it does for 7.1-channel
surround are different from those for 5.1-channel surround or for stereo.
This means the DSP does optimal simulation computations according to the
configuration of speaker setting.
Blue ball: receiver’s position (seating
position)
Brown ball up front: sound source (stereo
2-channel)
3 red balls up front: sound source (left,
right and center channels)
2 red balls in the rear: sound source
(surround left and right channels) (5.1-
channel surround consists of five red balls.)
4 green balls to the sides and in the rear:
7.1-channel surround consists of three red
balls and four black balls.
