Effects Flashcards
When were the early forms of analogue delay?
Tape delay in 40s and 50s
How did tape delay work?
Audio picked up onto tape by record head, would play back across playback head, creating repeat. Repeats would degrade in quality each time.
What delay was developed in the 70s?
Bucket-Brigade delay
How was bucket brigade different to tape delays?
Degrades in different way to tape delay so has distinct sound
Smaller so could be installed in foot pedals
More affordable
When were digital delays developed?
Early 80s
How does digital delay work?
Converts incoming audio signal into information via ADC, then stores digital information as binary data, and after required amount of time, signal is played and converted back to audio
How are digital delays different?
Less degradation with repeats
What was the first type of reverb?
Chamber reverb- playing recorded sounds through different rooms and capturing resultant ambience with mic
When was plate reverb developed?
1950s
How did plate reverbs work and give a model?
Signal is fed onto large metal plate via drive transducer and captured at different points on the plate with one or two pickup transducers
EMT 140
When were spring reverbs developed?
1930s
How are spring reverbs different to plate reverbs?
Similar mechanics to plate reverb just with spring instead of plate
They’re smaller so are commonly found in guitar amps
Have distinctive, bright, brittle sound
When was Convolution reverb developed?
Developed in 90s but only because common in 2000s
How does convolution reverb work?
Recreates exact reverb characteristics of specific spaces using samples of existing reverb tails
How does phaser work and when was it developed?
The incoming signal is split in two and one of them is phase shifted and then laid on top of the other, creating a notch due to phase cancellation. The notch is then swept along a range of the frequency band.
Developed in late 60s
