1

What is reverb?

Reverb is essentially reflections which which persist after the original sound has diminished. The reflections diminish gradually in amplitude and the time this takes depends on the environment

2

How is reverb generates in modern recording studios

Using digital algorithms and plug ins, recreating reverb characteristics and ambiance

3

What is convolution reverb?

This stimulates the reverberation of a physical space or performance venue

4

What is Pre - delay?

Refers to the amount of time between the original dry sound and the audible onset of early reflections and reverb tail

5

What is reverb time?

The time taken for the reflections to diminish by 60dB from the first reflection

6

Why does room size matter in reverb?

The room size alters the delay times of the early reflections of reverb creating the effect of a larger or smaller space

7

What is diffusion in reverb?

Diffusion creates the character of the reverb tail. Higher diffusion is smoother while less diffusion can be clearer

8

How does width effect reverb?

Width increases the stereo image response of the reverb

9

What does HF damping do?

HF damping increases or decreases the loss of high frequency detail in the reverb tail as it diminishes.

10

What is Gated Reverb

Micing the ambience of a room, often heavily compressed using a noise gate to produce a sharp cut off

11

What is reverse reverb?

A modification of gated reverb where a reverse type envelope is applied to the early cluster of reflections. Sound sounds backwards even though it is not

12

Chamber reverb/echo chamber

Sending signal to a loudspeaker in the chamber a mic picks up. The wet signal is blended with the dry signal.

13

What is plate reverb?

A transducer creates vibrations in a large plate of sheet metal. A pickup captures the vibrations and the result is an audio signal

14

What is spring reverb?

A transducer at one end of a spring and a pickup at the other to create and capture vibrations.

15

What is delay?

An audio effect which records an input signal to an audio storage medium then plays back after a period of time.

16

What is the earliest forms of delay and how did it work?

Reel to reel tape machines where the record head of the tape machine was converted to another playback head, the difference in the distance between the two heads created a short delay called tape echo or slap back echo

17

What options do digital delay units present?

Control over the time before playback
Select overall level of the processed signal
Level the delay signal is fed back into the buffer to be repeated
Audio filters
Multi tap delays

18

What do software delay systems allow us to do?

Manipulate several parameters in the delay

19

What is delay time?

The time between each delayed repetition

20

What is feedback?

The length of time that the delayed repetitions last for

21

What does EQ and filters do?

Shape the tone of the delayed signal

22

What is mix level?

The balance between the original signal and the processed delayed signal

23

What is panning?

Stereo delays allow the user to pan each side

24

What is a flanger?

A time based effect that occurs when two identical signals are mixed together but with one signal time delayed by a small and gradually changing amount

25

What is phasing?

The properties are similar to Flanders but a phaser uses all pass filters which are fed back into themselves

26

How was flanging originally created?

A signal would be recorded to two tape machines. An engineer would put a finer on the flange of one of the tape machines to make it slip in and out of sync
