delay

Question 1

what is delay?

Answer 1

a repeated signal that creates an echo

Question 2

what is the difference between analogue and digital delay?

Answer 2

analogue delay captures sound as continuous waveforms of acoustics whereas digital delay converts sound into binary to create a delay

Question 3

what is delay time?

Answer 3

the amount of time between an original signal and a delayed signal (gap between each repeat)

Question 4

what is feedback?

Answer 4

when delayed signal is fed back into the input of delay - the more feedback there is, the more number of repeats

Question 5

3 features of tape delay…

Answer 5

• analogue
• recorded sound onto magnetic tape then played it back
• tape would eventually degrade and need replacing as high frequencies were lost giving it a ‘warm feel’

Question 6

3 features of bucket brigade delay…

Answer 6

• these chips were used to store original sound
• signal is held in each capacitor then moved onto the next holding place to create a delayed signal
• chips were more reliable but noisy - longer delays = more noise

Question 7

3 features of slap-back delay…

Answer 7

-originally analogue with a repeat after 80-200ms
- almost percussive effect, repeat is high level enough to be noticeable
- heard in Rock N Roll 1950s, used to thicken vocals and electrical guitar

Question 8

what does multi-tap delay do?

Answer 8

• allows several delay times in one effect

Question 9

what does ping-pong/stereo delay do?

Answer 9

• gives the option to pan delayed sound
• sometimes multi-tap delay will pan each ‘tap’ in a different direction and allow other features such as volume and filtering

Question 10

what is a doubling effect?

Answer 10

• it thickens the signal to sound like 2 simultaneous versions of the original
