Interaural Level and Time Differences as
Related to 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 an
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 an
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 Angle value (and/or angle of an actual loudspeaker
placement), the greater the effect will be of shifting the opposite side
toward more deeply lying frequencies, since with an increased spatial
arc around the head only lower frequencies will undergo proportionate
modification.
It should also become apparent that the Angle control is primarily de-
pending on interaural time differences. Its influences on level differ-
ences are in contrast, comparatively slight.
