Chapter 28: AIR Spring Reverb
AIR Spring Reverb is an RTAS plug-in. Use the
Spring Reverb plug-in for that classic spring re-
verb sound. Just don’t kick your computer try-
ing to get the springs to rattle!
The Spring Reverb plug-in models an analog
spring reverb. An analog spring reverb is an
electromechanical device much like a plate re-
verb. An audio signal is fed to a transducer at
the end of a long suspended metal coil spring.
The transducer causes the spring to vibrate,
which results in the signal reflecting from one
end of the spring to the other. At the other end
of the spring is another transducer that converts
the motion of the spring back into an electrical
signal, thus creating a delayed and reverberated
version of the input signal.
Spring Reverb Controls
The Spring Reverb plug-in provides a variety of
controls for adjusting plug-in parameters.
Pre-Delay
The Pre-Delay control determines the amount of
time (0–250 ms) that elapses between the origi-
nal audio event and the onset of reverberation.
Reverb Time
Adjust the Reverb Time to change the reverber-
ation decay time (1.0–10.0 seconds) after the
original direct signal stops. Shorter times result
in a tighter, more ringing and metallic reverb,
such as when walking down a narrow hall with
hard floors and walls. Longer times result in a
larger reverberant space, such as an empty,
large, concrete cistern.
Mix
The Mix control lets you adjust the Mix between
the “wet” (reverbed) and “dry” (non-reverbed)
signal. 0% is all dry, and 100% is all wet, while
50% is an equal mix of both.
Low Cut
The Low Cut control lets you adjust the fre-
quency of the Low Cut Filter
(20.0 Hz–1.00 kHz). Use the Low Cut filter to re-
duce some of the potential “boomyness” you can
get with longer Reverb Times.
