1
Good-quality Masters can be achieved with:
only digital Mastering processors
only analog Mastering processors
both analog and digital Mastering processors
2
A "character" EQ:
is an EQ that's only suitable for one particular EQ application, as specified by the maker
has none of the phase shift common to normal ("minimum-phase") EQs, for more transparent sound
is one that's endorsed by a well-known, perhaps somewhat opinionated, Mastering engineer
is often an emulation of analog circuitry, like tubes and other vintage designs
3
The three most basic tools of Mastering are:
Compression, Delay, Limiter
EQ, Compression, and (Brickwall) Limiting
Loudness Maximizer, Loudness Maximizer, and Loudness Maximizer
EQ, Pitch Correction (Auto-tuning), and Time-Shifting
4
In the heyday of the analog (pre-digital) era, a big part of Mastering was:
adding ISRC codes to the finished recordings
All other answers are incorrect
squeezing audio into the more limited dynamic range of vinyl
keeping audio levels below 0 dBfs
5
Decent Mastering results can never be achieved by anyone outside a high-end commercial Mastering room. True or false?
True
False
6
ISRC:
is a new proposed file format for the highest-quality masters, using 64 bps MP3 format for maximum clarity
None of the other answers are correct
is the organization that sets the standard for how much Limiting can be applied in modern mastering
refers to embedded (text) metadata in audio masters, that's used for tracking distribution and sale
7
What is the Nyquist Theory?
A minimum Sampling Rate via digital recording must be half the highest recorded audio frequency
A minimum Sampling Rate via digital recording must be twice the highest recorded audio frequency
8
Most Mastering engineers would say that the best curve for a Fade (at the end of a song) is:
a linear cross-fade
an exponential fade-out
a logarithmic fade-out
an "S" curve fade-out
9
Which would be the best strategy for a Mastering session with several songs for a collection/album?
All other answers are incorrect
having a separate chain of mastering processors on each track, for each individual song
never mastering more than one song, per session, at a time, even for an album
having a single chain of mastering processors inserted in the stereo output channel, affecting all songs
10
Which of the following is an advantage of bringing a mix to a dedicated Mastering engineer?
He'll be more experienced with the kinds of problems that need to be addressed in Mastering
He'll hear the song with fresh ears, and be more likely to pick up on subtle issues & problems
All answers are correct
He's likely to be working out of an acoustically treated room with calibrated monitors
11
__________ refers to the number of bits used for the Binary Number that describe the Amplitude levels of the Audio Samples.
Dynamic range
Bit Resolution
Dithering
Sample Rate
12
A Multiband compressor:
is typically 3 or 4 compressors in one, each applying compression independently to a different frequency band
is a compressor that must be used on all songs being mastered for a collection, to insure compatibility
is a compressor designed to work equally well on bands in many very different-sounding musical genres
None of the other answers are correct
13
Dither:
only needs to be applied to 16-bit master files (as for CD Duplication masters)
always must be applied all all bounces, at any resolution, up to 32-bit
only needs to be applied to 24-bit master files, for modern production standards
All answers are correct
14
In a typical un-processed musical wave:
None of the other answers are correct
the difference between momentary Transient Peak levels and Average levels can be as much as 15-20 dB
all wave heights are identical in a good performance-this level consistency is the hallmark of great performances
there are no Transient peaks-these are an artifact of the mastering processing, and must be removed at the end
15
Inter-Sample peaks:
All answers are correct
are an artifact of D->A conversion, and can cause slight overages, of often half a dB or so, above the digital maximum
can never be predicited or anticipated-you can never know for sure how many there are, or how severe they might be
are distortions that creep into the mastered file when you take a break and someone changes the settings on the Limiter
16
Brickwall Limiting:
was originally designed to prevent digital overs (clipping), but is now also used to "maximize" level
removes frequencies above 20 kHz and below 20 Hz, to remove any problematic supersonic and subsonic elements
is designed to keep the mix from being raised in volume too much, by applying an AI algorithm
17
The process of assigning Binary numbers to describe sample levels is called:
Sample rate resolution
Quantization
Bit Rate assigning
Binarization
18
In a Mastering session, "Reference tracks" would be:
several high-quality commercially-released songs, mastered by top pros, for use as a reality check
several of the loudest-mastered songs you can find, to make sure all your masters are also the loudest
a collection of poorly-mastered songs, to remind you what not to do
All other answers are incorrect
19
When applying Brickwall Limiting to raise the level of a track:
the output ceiling should be set just a little below maximum digital ceiling (0 dBfs), at around -0.3 dBfs or so
the output ceiling should be set at exactly 0 dBfs or, if possible, just a little higher, for maximum effect
the output ceiling should be set at around -3 dBfs or so to avoid any peaks
the output ceiling should be turned off, and any peaks should be removed by editing wth Pencil tool
20
A Multiband compressor:
None of the other answers are correct
may have different settings in the different bands, for the most appropriate compression at different frequencies
divides the frequency range, but has only one set of controls that affects all frequency bands the same
must always have the same settings in all bands, or else there will be "pumping" and "breathing" artifacts
21
What is the highest-quality audio spec for modern Masters?
24-bit WAV
24-bit MP4/AAC
16-bit WAV
24-bit MP3
22
Which of the following would be an appropriate part of Pre-Mastering?
Preparing vocal-up & vocal-down versions, and stems
Adding Dither to the 24-bit pre-mastered mix file
Maximizing the level of the mix as loud as possible
All answers are correct
23
A "linear-phase" EQ:
is technically no differents from a standard "minimum-phase" EQ-it's purely marketing hype
has none of the phase shift common to normal ("minimum-phase") EQs, for more transparent sound
has the same amount of phase shift in every instance, so all EQ'd songs are phase-shifted consistently
is a specialty EQ that analyzes the audio, and automatically applies the correct ampunt of EQ for the musical genre
24
Ratios for compression (especially Multiband compression) in Mastering:
are always set to 1:1, to insure the most transparent quality
are always set to 10:1 to insure that the audio is loud without any peaks
are more typically on the high side-around 6:1 or higher
are more typically on the low side-around 2:1 or lower
25
The Nyquist theory says that the minimum sample rate for digital recording must be twice the lowest audio frequency to be recorded. True or false?
False
True
