MUS 4130 Final Exam 2023, With complete
solution
The lowest frequency (tone) in a musical note is known as the:
fundamental
Harmonics in a musical tone are:
all vibrations above the fundamentals
Another term for the pitch (or tone) of an audio waveform is:
frequency
Another term for the quality (or tone color) of an audio waveform is:
timbre
Another term for the elapsed time of a sound is:
duration
Another term for the height (or strength) of an audio waveform is:
amplitude
A form of synthesis based on Fourier analysis is:
additive synthesis
In ring modulation
the fundamental frequency is suppressed, leaving only its sidebands/harmonics
What are the components of a waveform?
equilibrium, period, and displacement
The duty cycle of a waveform is:
a ratio denoting proportions of a waveform with respect with its equilibrium point
What are some non-sinusoidal waveforms?
Rectangular, Triangle, and sawtooth
A device for detecting sounds transmitted in the air is:
a microphone
Acoustic feedback is created when
a signal is amplified and re-amplified by a microphone and a speaker within close
proximity to one another
A sequencer is used to:
create, edit, and play prescribed sequences of notes and rhythms
Attack, decay, sustain, and release refer to what aspect of a sound?
its sound envelope
In amplitude modulation
a control voltage is used to alter the loudness of an audio signal
In frequency modulation
a control voltage is used to alter the pitch of an audio signal
A key component of any analog synthesizer is the
audio oscillator, envelope generator, and voltage-controlled amplifier
The first pioneering programming work in computer music took place at which
institution?
Bell Telephone Laboratories
Algorithms that can be organized as a sequence of instructions for a computer is
known as:
