An audio track is typically successful
when it does not draw attention to itself
Sound travels as
a wave
Amplitude refers to
the loudness of a sound wave
The frequency of a sound wave defines its
pitch
A highly directional microphone that is used to pick up sound from a distance is a ______________ microphone
shotgun
A small, clip-on microphone that allows hands-free pickup of a talent's voice is a
lavaliere microphone
The human ear can hear frequencies between
20Hz and 20,000Hz (20kHz)
Amplitude is measured in
decibels (dB)
To store sound waves digitally on a computer it is necessary to use a/an
Analog-to-Digital Converter (ADC)
A higher bit rate while recording audio
leads to better accuracy of the file
increases the file size
provides higher quality recordings
You can control the signal to noise ratio while recording by
placing the microphone closer to the talent
Recording double system requires
using a slate
an external recording device
True or False? As long as you're monitoring the sound waves on your recording device, you do not need headphones.
False
The directional (or cardioid) mic pickup pattern
does not pick up sound from the rear side
Acoustic panels placed on the walls of an audio room
reduce the "liveness" of the room
True or False? While recording in open spaces, it is necessary to place the boom mic far from the sound source because it's safer and open air sound travels far.
False
Acoustically, hard surfaces cause reflection of sound waves which creates
reverberation
When talent needs unrestricted mobility, these two microphone systems are often used
wireless or boom
A common device used to monitor volume levels is the
VU meter
