Quiz #3

Question 1

Compressor

Answer 1

Applies negative gain at a low ratio above a set threshold

Question 2

Expander

Answer 2

Applies negative gain determined by a ratio below a set threshold

Question 3

Limiter

Answer 3

Applies negative gain at a high ratio above a set threshold

Question 4

Noise Gate

Answer 4

Applies infinite negative gain below a set threshold

Question 5

Comb filter

Answer 5

Short delays producing a ‘flanging’ sound when swept through a signal

Question 6

Cutoff frequency of a filter

Answer 6

Defines where on the spectrum, it will act, the slope defines the amount of attenuation over that range

Question 7

Common parameters of a Compressor

Answer 7

Ratio, Make-up gain, Threshold

Question 8

Common parameters of an EQ

Answer 8

Q, Shelf, Peak, Parametric

Question 9

Common parameters of a Reverb

Answer 9

Decay, Diffusion, Dampening, Pre-delay

Question 10

Sampling higher allows us to

Answer 10

Digitalize higher frequencies

Question 11

The Nyquist Theorem states that

Answer 11

We must sample twice the rate of the frequencies we wish to reproduce

Question 12

A higher bit depth allows for

Answer 12

The reproduction of a higher dynamic range

Question 13

Dithering introduces noise that can

Answer 13

Mask severe aliasing or quantizing noise

Question 14

Formats

Answer 14

Unlike .WAV or .AIFF files Apple Audio (AAC - Like in your iTunes) is a compressed format or what we would term lossy as opposed to lossless

Question 15

Granular synthesis

Answer 15

Creation if sounds from assembling many short sounds

Question 16

Waveshaping is

Answer 16

Creating sounds through using mathematical formulas

Question 17

Subtractive synthesis is

Answer 17

The process of using filters to shape up the spectra of a complex wave

Question 18

FM synthesis

Answer 18

Is using one wave to vary the rate of vibration of another

Question 19

AM synthesis

Answer 19

Is using one wave to vary the magnitude of vibration of another
