Uncorrelated signals; same level in
the L, R, Ls, and Rs channels. Sine wave test tone; same level in
the L, R, Ls, and Rs channels.
All signals are in phase, creating
phantom sources between the
adjacent channels. Sine wave test tone; same level in
the L, R, Ls, and Rs channels.
Channels R, Ls, and Rs are in
phase, creating phantom sources
between the adjacent channels.
Channel L is out of phase.
Surround sound program with strong
center channel presence. Surround sound program with weak
center channel presence.
