to define what reverb is in
order to understand how it is created.

Reverberation is the persistence of sound in a particular space
after the original sound is

A reverberation, or reverb, is created when a sound is
produced in an enclosed space causing a large number of
echoes to build up and then slowly decay as the sound is
absorbed by the walls and

It is added to recordings made using close


Reverb levels can therefore be controlled by an engineer or

Reverb is an auxiliary effect.

Reverb can be found in guitar amplifiers, FX pedals, dedicated
hardware or added with a software plug

Natural reverb is captured using ambient

techniques. i.e.
more reverb is captured if a microphone is further away.

Omnidirectional or figure of 8 microphones pick up reverb
better than cardioid

Room acoustics determine the nature of reverb.

In the 1950’s reverb was made by playing a dry signal in a
room, placing a loudspeaker at one end and an omnidirectional

at the other.

The height and angle of the microphones affects the amount of

These rooms had to be built using reflective material like stone
or concrete. (Garages or stairwells are popular with home

Large metal sheet! Sound
input by a speaker
transducer causing the sheet
to vibrate. Reflections from
the sheet are picked up by
like transducers.

Reverb time is controlled by
a dampening pad used to
absorb the reflections more

Very expensive!

Gives very dense reverb
and still used today on

Similar to plate reverb but a spring is used instead of a metal
sheet. It is also smaller and has a characteristic

Reverb time can be adjusted by the amount of tension in the
spring. Spring reverbs tend to have a mid
range boost and long
reverb time.

Appeared in the 1980’s.

A signal is input into a computer algorithm which consists of
many delays and echoes which emulate real spaces.

Is easily changed and adjusted. Early reflections are more
prominent than in spring/ plate reverb so they sound more

Digital reverb is very heavy on the CPU. As CPU’s got faster the
realism of reverb improved.

In the late 1990’s digital reverbs became software plug
ins in
sequencing packages (like
