Parameters for defining attenuation
characteristics of early-reflected sound
Liveness / P. Liveness / Sur. Liveness / Sur. Back
Liveness
Adjustable range: 0 to 10
Adjusts the attenuation of reflected sound. You can create
a lively sound field (with a high reverberant sound level)
as you increase the value, and a dead sound field (with a
low reverberant sound level) as you decrease the value.
Creating either a lively sound field or a dead sound field in
an actual music hall is determined by the acoustic
absorption characteristics of reflection surfaces. A dead
sound field is created when the attenuation time is short
while a lively sound field is created when the attenuation
time is long.

Parameters for adjusting reverberant sound
Reverb Time
Adjustable range: 1.0 to 5.0s
Reverb Time parameter adjusts the attenuation time of the
rear reverberant sound based on the time that about 1kHz
reverberant sound takes for 60dB of attenuation.
Reverberant sound attenuates faster as you decrease the
value. Reverb Time adjustment allows you to create a
natural reverberant sound, by setting the attenuation time
longer for a sound source or room with less echo, or
shorter for a sound source or room with more echo.

Reverb Delay
Adjustable range: 0 to 250ms
Reverb Delay parameter adjusts the time difference
between the beginning of the direct sound and the
beginning of the reverberation sound. The larger the value,
the later the reverberation sound begins. Increasing the
value of Reverb Delay allows you to create a reverberant
sound in a wider area for the same Reverb Time.
