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
How is reverb generates in modern recording studios
Using digital algorithms and plug ins, recreating reverb characteristics and ambiance
What is convolution reverb?
This stimulates the reverberation of a physical space or performance venue
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
What is reverb time?
The time taken for the reflections to diminish by 60dB from the first reflection
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
What is diffusion in reverb?
Diffusion creates the character of the reverb tail. Higher diffusion is smoother while less diffusion can be clearer
How does width effect reverb?
Width increases the stereo image response of the reverb
What does HF damping do?
HF damping increases or decreases the loss of high frequency detail in the reverb tail as it diminishes.
What is Gated Reverb
Micing the ambience of a room, often heavily compressed using a noise gate to produce a sharp cut off
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
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.
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
What is spring reverb?
A transducer at one end of a spring and a pickup at the other to create and capture vibrations.
What is delay?
An audio effect which records an input signal to an audio storage medium then plays back after a period of time.
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
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
What do software delay systems allow us to do?
Manipulate several parameters in the delay
What is delay time?
The time between each delayed repetition
What is feedback?
The length of time that the delayed repetitions last for
What does EQ and filters do?
Shape the tone of the delayed signal
What is mix level?
The balance between the original signal and the processed delayed signal
What is panning?
Stereo delays allow the user to pan each side
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
