Class 1

Question 1

clues about environment

Answer 1

tonal balance + frequency content

Question 2

comb filtering

Answer 2

sound is mixed with another version of itself (like uneven room with sound hitting at different times)

Question 3

timbre

Answer 3

spectral content (frequencies present), spectral balance, amplitude envelope

Question 4

amplitude envelope

Answer 4

attack decay sustain release

Question 5

technical ear training

Answer 5

learning how timbre reacts to signal processing

Question 6

how can we impact timbre

Answer 6

EQ, filtering, reverb and delay, dynamics processing, panning

Question 7

dynamics processing?

Answer 7

compressor limiter gate expander

Question 8

artifacts

Answer 8

noise, hum, buzz, unintentional (digital) distortion

Question 9

4 goals of technical ear training

Answer 9

link audio attributes to perception, increase ability to hear subtle details of sound, increase speed of recognition, consistency in judgments

Question 10

subtle detail categories

Answer 10

mic, preamp, signal levels, spectral balance, dynamics processing, spatial characteristics, balance, processing effects, noise

Question 11

microphones

Answer 11

make, model, polar pattern, location, orientation

Question 12

preamp

Answer 12

make, model, gain settings, optimizing to avoid clipping

Question 13

signal levels

Answer 13

can be several gain stages for each track, what equipment is in signal chain. MAXIMIZE THE SIGNAL TO NOISE RATIO, MINIMIZE AtoD CONVERSION QUANTIZATION ERROR AND CLIPPING

Question 14

spectral balance

Answer 14

EQ and filter settings for each track

Question 15

dynamic processing

Answer 15

altering range through compressors and expanders

Question 16

spatial characteristics

Answer 16

room acoustics, mic placement in room, settings of reverb, delay, panning

Question 17

balance

Answer 17

relative levels of tracks

Question 18

processing effects

Answer 18

flanger, phaser, chorus, tremolo, distortion/overdrive

Question 19

noise

Answer 19

any sound not intended to be part of a recording

Question 20

too much noise?

Answer 20

roll out the lows

Question 21

mono/monaural

Answer 21

single speaker

Question 22

stereo

Answer 22

2 speakers

Question 23

mono in stereo

Answer 23

pseudo mono (same out of left and right)

Question 24

harmonic distortion

Answer 24

overtones rather than ground loop (60Hz) or artifacts and digital clipping

Question 25

headphone pros

Answer 25

clarity, cost

Question 26

headphone deltas

Answer 26

in-head localization - lose sound reflection

Question 27

speakers pros

Answer 27

accurate representation of what we hear, wider frequency range

Question 28

speaker deltas

Answer 28

cost

Question 29

OSHA says sound should be below ____ dB to prevent hearing loss during 8 hour day

Answer 29

85dB
