Interaural Level and Time Differences as Related
to Speaker Angle Setup
The following two diagrams show (on the left) the frequency response
of interaural level difference with respect to the interaural time differ-
ence (on the right) at maximum Crossfeed value and a
Speaker Angle
of 75 degrees.
The following two diagrams show, respectively (on the left), the fre-
quency response of the interaural level difference and the interaural
time difference (on the right) at a maximum Crossfeed value and a
Speaker Angle of 15 degrees.
The black curves stand for the side of the direct sound wave front,
while the gray curves stand for the opposite side.
The larger the Speaker Angle value (and/or angle of an actual loud-
speaker placement), the greater the effect will be of shifting the oppo-
site side toward more deeply lying frequencies, since with an increased
spatial arc around the head only lower frequencies will undergo pro-
portionate modification.
It should also become apparent that the Speaker Angle control is pri-
marily depending on interaural time differences. Its influences on level
differences are in contrast, comparatively slight.
