the loudest perceived track in a mix
3
The "mirror trick" is...
a technique to imitate the playing style of another musician
a simple way to locate problematic reflections
a psychological method for getting a good take from an artist
a way to create sight lines from control room to live room
4
Phase is...
a period when novice mixers tend to use too much EQ
an effect generated with a ≥50-mlliisecond delay
a measurment of the period of one cycle of a sound wave
5
In a reverberant sound field, diffusion relates to...
the density and timing of reflections
In a reverberant sound field, diffusion relates to...
the relative level of the dry signal and the reverb signal
the number of different spaces provided in a reverb plug-in
6
Absorption occurs when sound waves hit...
a flexible room boundary
a porous surface like foam
another wave
a hard surface like wood or glass
7
Golden Mean room dimensions are intended to minimize the incidence and severity of standing waves. True or false?
False
True
8
Comb filtering is caused by...
too much processing
reinforcements & cancellations from reflected waves
the gradually decreasing level as a sound wave dies away
an effect that slightly clips the audio wave
9
An anechoic chamber is...
a very live space, usually for testing applications
an echo chamber
a completely dead space, usually for testing applications
a Live-End Dead-End™ space for mixing
10
The Haas Effect specifies two "zones":

the Fusion zone & the Echo zone
the Fission zone & the Reverb zone
the Echo zone & the Reverb zone
11
A bass trap is...

the bass port in some speaker designs
all answers are correct
12
The control room contains...

13
Live End Dead End ™ is an approach to...

14
One effective technique for soundproofing a studio is...

18
A reverberant sound field consists of...

an impulse and a response
dense reverberation, phasing effects, & compressed echoes
dense reverberation, flanging effects, & compressed echoes
19
The Inverse Square Law addresses...
increasing level with greater distance from the source
decreasing level with greater distance from the source
consistent level despite greater distance from the source
inconsistent level in square waves
20
Wavelength is...
the distance a wave travels in the time it takes to complete one cycle
the length of a sustaining note, like from an organ
the decay time of a note with a gradual falloff in level
the length of a song
21
Standing Waves (or Room Modes) are...
different room shapes for control room designs
irregularities in low-frequency reponse at different locations in a room
irregularities in high-frequency reponse at different locations in a room
