ACCESS VIRUS OS4

Delay/Reverb

dial in the minimum value, the 
decay time is extremely short so 
you’ll hear just the early reflec-
tions. At the peak value, no energy 

is lost so the decay time is infinite, 
which is of course physically 
impossible in the real world.

This parameter controls high-fre-
quency attenuation of the room’s 
fading reflections.

In a real room, walls don’t reflect 
high frequencies as well as they do 
lower frequencies, an effect that 
can be likened to natural low-pass 
filtering of the sound. The longer 
the sound travels, the more often 
it bounces off walls and the more 

intense this filtering effect. For this 
reason, the amount of high-end 
damping depends on the amount 
of time that the signal carries - the 
signal thrown back by the room 
becomes muddier as time goes by. 
This effect is stronger with walls 
that have soft surfaces (wood, 
wallpaper) than it is with walls 
that have hard surfaces (glass, 
tiles). Consequently, high-end 
damping has a significant influ-
ence the vibe and warmth of the 
room sound.
