Time-based Processors Flashcards
5 sources of reverb
- Acoustic reverberation
- Echo chamber
- Plate reverb
- Spring reverb
- Digital reverb devices
Oscillation with high rate and low depth
Phaser
Oscillation with low rate and high depth
Flanger
Room with no reverb
Anechoic chamber
Delay with 0% feedback
Slapback
Multi-voice oscillation
Physical movement of multiple voices against each other
Percentage of the original signal in the first repeat in delay effect
100%
When there is a difference in ________, there will be a difference in ________. When there is a difference in ________, there will be a difference in _________.
Time, Phase, Phase, Tone
Examples of Time-based processors
Chorus, Delay, Reverb, Phaser
Reverb
Random multiple echoes
Room built specifically for reverb
Echo chamber
Type of reverb most typically found in guitar amps
Spring reverb
Reverb happens in the brain - true or false?
True
3 components of reverb
- Direct signal
- Early reflections
- Reverberation
Direct Signal
The point in time at which the original sound wave is received by the listener
Early reflections
The first few reflections that are projected to the listener within a determined space
Reverberation (3 components of reverb)
The point in time where the brain cannot discern the reflections separately because they are so tightly spaced (reverb tail)
Acoustic reverberation
Utilising the natural amount of reverb that an environment has
Plate reverb
“Plate” of sheet metal inside a wooden box, suspended on all four corners
Spring reverb
Like a plate reverb but has springs
Digital reverb devices
Can do any type of room/environment, simulates all other reverbs using algorithms
3 common parameters of digital reverb
- Room-size control
- Pre-delay
- Reverb time (decay time)
Room-size control
Room type/reverb type
Pre-delay
The amount of time after the direct signal, before the early reflections (milliseconds of pre-delay)
