A typical HRIR can
be decomposed into a
series of temporal
sound events as
shown above. First
of all, there is an
initial time
delay(ITD) due to
the distance between
the sound source and
listener's ear. A
direct pulse, whose
amplitude depends on
the source distance
and shadow effect,
arrives after the
ITD period. The rest
of the signal
contains reflections
from shoulder,
torso, and
measurement devices.
In view of system
characteristics, ITD
does not have
information to
describe HRTFs of
HRIRs. Moreover,
reflections or
diffractions from
the environment have
to be neglected to
obtain HRTFs.
We
publish cleansed
HRIRs for Median
plane, Vertical
plane, Horizontal
plane. A cleansed
HRIR has a response
range from the first
direct pulse to the
reflection of the
turn table - for
about 2.3ms.
Published(cleased) HRIR
consists of 100 data
signals for each.
