spatial effects processing and modulation effects

Question 1

what is delay?

Answer 1

Delay is an audio effect which is designed to store signal for a specified period of time, which after the amount of time it then releases, creating the signal that was captured to echo or repeat several times; each time the sound is repeated the volume level decreases

Question 2

what is tape delay?

Answer 2

delay achieved by using magnetic tape loops, shortening and lengthening the tape and adjusting tape heads to alter the delay settings

Question 3

what are the controls of delay?

Answer 3

delay time - how frequent it is repeated
feedback - how much of the delay signal is being pushed through the processor again
EQ/filter - used to remove/boost high or low frequencies
panning - whether the use of stereo delay is needed or not

Question 4

what is ADT and who invented it?

Answer 4

automatic double tracking imitates the effect of doubling voices or instruments using double tracking, without the need for a musician to overdub their part
Abbey road studio engineers working on The Beatles invented ADT doing the late 1960s using tape delay

Question 5

what is the definition of modulation effects?

Answer 5

effects that add movement and depth to a sound, achieved by duplicated audio signals being delayed and automated by an LFO

Question 6

what is an LFO?

Answer 6

an audio signal lower than 20Hz, produces a sine wave inaudible to the human ear

Question 7

what is chorus?

Answer 7

it makes one instrument or voice sound like many, this is done by modulating the delayed signals with an LFO creating a slight pitch and time adjustment

Question 8

name a song that uses chorus

Answer 8

Nirvana - Come as you are

Question 9

what is a flanger?

Answer 9

it creates an atmospheric sound that is sometimes described as an under water or whoosh sound

Question 10

how is flanging created?

Answer 10

mixing a signal with a slightly delayed copy of itself, where the length of the delay is constantly changing with the use of an LFO

Question 11

what is a phaser?

Answer 11

similar effect to flanging, but phasers split the signal, one part goes through an allpass filter then into an LFO then recombine with the original sound

Question 12

name a song that uses a phaser

Answer 12

Pink Floyd - Have a cigar

Question 13

what is tremolo?

Answer 13

an effect where the LFO is modulating the volume of a signal

Question 14

what is vibrato?

Answer 14

an effect where the LFO is modulating the pitch of a signal
