Chapter 6 Digital Reverb

Question 1

Chamber

Answer 1

A large room designed and built for the purpose of creating reverberation under carefully con- trolled circumstances. Reverb chambers have a speaker at one end and a pair of microphones at the other to capture the room’s natural reverberation. Chamber reverb is often simulated on modern digital reverb units.

Question 2

Decay Time

Answer 2

The amount of time reverberation lasts. Larger acoustic spaces are simulated with longer decay times.

Question 3

Diffusion

Answer 3

The density of reflections returning to the listener. This determines the thickness of the rever- beration.

Question 4

Hall

Answer 4

Digitally created reverb that simulates a large acoustic space (like a concert hall). It is a common reverb type on modern digital reverb units.

Question 5

Mix

Answer 5

The reverb mix controls the mixture of uneffected sound verses effected sound. Mix is usually ex- pressed as a percentage where 100% is only effected signal and 0% is only uneffected signal. Mix amount is determined by the method in which the reverb unit is connected to the system. When used with aux sends/returns, reverb mix is set to 100% while when used as an insert, it should be set to taste.

Question 6

Plate

Answer 6

A plate reverb unit contains a speaker which causes a large, tuned metal plate to vibrate sympatheti- cally. These vibrations are then picked up by a microphone. Plate reverb is often simulated on modern digital reverb units.

Question 7

Predelay

Answer 7

A delay between the start of the original signal and the time at which reverberation begins. Predelay time is measured in milliseconds. Longer predelay times cause the perception of a larger acoustic space.

Question 8

Reverberation

Answer 8

The sound our ears perceive when many reflections return to us very quickly. Because the ear is not able to distinguish the individual signals we perceive one sound. Reverberation is the most common effect used in any studio.

Question 9

Reverb

Answer 9

Another term for reverberation.

Question 10

Reverb Time

Answer 10

Another term for decay time.

Question 11

Room

Answer 11

Room reverb is digitally created reverb that simulates a small acoustic space, usually more than 125,000 cubic feet. It is a common reverb type on modern digital reverb units.
