Effects - Reverbs and Delays Flashcards
What Is Reverb?
The persistence of sound after it has been produced. Used commonly in recorded music.
What Is Delay?
A time effect that postpones the sound from playing for a number of milliseconds.
Echo
Sound repeating after the initial sound is played.
Tape Delay
A signal is recorded onto tape which is passed in front of a reading head to be played out of a speaker further away creating a delay.
Analog Delay
Takes a sample from the original signal and passes it along to the next capacitor.
- Similar results to tape delay but with a much darker sound
- Delays were shorter making them more suitable for ‘slapback’ delay
Chamber Reverb
An artificial reverb created through the recording of a track in a reverb chamber.
- Generous and Dense Reverb
- Less duration and more focused than Hall reverb
Hall Reverb
Replicates the sound of a large concert hall
- Often very long decays
- Used frequently on orchestral instruments to thicken up the sound of a piece
Gated Reverb
Used when applying a large reverb to a track before cutting the reverb off to a degree using a noise gate.
- Commonly used on Snare and kit recordings
Spring Reverb
Introduced with the Hammond organ in the 1960s to replicate church reverb. Works by transferring an audio signal through a spring (or springs) through a transducer.
Plate Reverb
Uses a large metal plate that is vibrated using a transducer. Introduced in 1957.
Convolution Reverb
Computer Generated reverb uses a recording of a physical space and calculates the exact amount of wet and dry sound that would be created by this space to get an ideal sounding reverb.
Digital Delay
Digital delays allow for precise timings to be placed onto a track along with a range of parameters that can be played around with e.g. variable feedback or output mix
Slapback Delay
A very short repeated echo introduced in the 1950s as a Rock n Roll guitar effect. Plays a slightly delayed version of the original sound into a microphone which plays almost straight back out as a delay.
Pre-delay
The time between the end of the initial sound and the the beginning of the first reflections being audible in the track. Measured in Milliseconds.
Delay Feedback
Determines the amount of repetitions on an output. The minimum number of repetitions when adding feedback is a single repetition of the original recording.
