AUDIO PROCESSING 2410 KAISER FINAL QUESTIONS
WITH COMPLETE SOLUTIONS
'change' the acoustic environment Correct
Answers temporal
'Pitch shifting' relies on _____ the amount of delay
in specific controlled ways in order to raise or lower
the original pitch by musical intervals. This 'effect'
was first made possible using ____, which changed
both the pitch and the _____ simultaneously.
Correct Answers changing; analog tape; tempo
'slap' or 'bounce' echo Correct Answers 50-150
ms
'Spectral processors' affect the balance between
the ____ and ____, which together make up the
'timbre' of the instrument. Correct Answers
fundament; overtones(harmonics)
(Basics & Design) 'Analog' spectral processors
operate as _____ functioning devices in the
frequency domain, while 'digital spectral
processors operate on _____ data in the time
domain. Correct Answers continuous, discrete
(Basics) There are three basic 'uses' for which
spectral processing can be applied in music
recording/mixing. These are (in order as we
,discussed them in class)... Correct Answers fix, fit,
feature
(EQ-IQ: Parameters) List TWO characteristics that
were ascribed in the EQ-IQ 'Parameters' video to
specific analog equalizers, e.g. API 550, Massive
Passive, etc. Correct Answers One characteristic
of Massive Passive is that it filters out the range of
7.5-9k frequencies. Another characteristic is that it
is a four-band two-channel equalizer.
(EQ-IQ:Intro) According to Alex Case, there are
many ways to affect 'spectral content' in a
recording WITHOUT using 'EQ'. Two of the variables
are ____ and ____ Correct Answers mic placement;
performance
(EQ-IQ:Process) According to Alex Case, the
conventional procedure for using an equalizer has
the following three steps (in sequence):___, ___,
and ___ . Correct Answers boost / search / set
(EQ-IQ:Process) Alex Case refers to the volume
control as a(n) '_____', because spectral changes
appear to us to be affected by _____. Correct
Answers perceptual EQ ; volume/level
(EQ-IQ:Process) Not all frequencies are present in
all genres of music. The range of the acoustic piano
represents the 'fundamentals' of most instruments,
, which include the frequencies from approx. ___ Hz
to ____ Hz. Correct Answers 30; 4000
(Estimating the Frequency of Sound) According to
this exercise, ____ (type of signal) is/are more
useful in equipment testing and measurement,
whereas ___ (type of signal) is/are more useful in
acoustic testing and measurement. Correct
Answers pure tones; pink noise
(How the Ear Analyzes Sound) The human auditory
system acts as a(n) '_____' . Using it, we can "hear
out' the harmonics of a complex sound until we
reach the point where two of these are within the
_____, which is about 15-20 % of the frequency
being considered. Correct Answers wave analyzer;
critical bandwidth
(Spectral Analysis) Identify what parameter each of
the 'letters' indicate in the display below... Correct
Answers A= amplitude/intensity
B= time
C= frequency
D= time
E= amplitude/intensity
