Audio Production Chapters 3 and 4
Common computer audio recording formats include all of the following except
According to your book, a commercial audio CD can hold approximately _____ minutes of music
75
While many computers can "burn" both CD-R and CD-RW discs but generally only ____ discs are playable on standard compact disc players.
CD-R
Compression scheme most frequently used to transfer audio files over the Internet is called
MPEG audio layer 3
Software that provides recording and mixing capabilities can turn into
a digital audio workstation
Super Audio CD and Audio DVD differ from standard CD's in that they:
all of the above
The purpose of a telephone hybrid to
allow talk show hosts to talk with callers on the air without feedback
A string of digital words is called a
byte
The digital process starts with converting sound into
data
Which is not one of the advantages of digital technology for broadcasting purposes
digital technology is easy to automate (only one that might not be right)
The ___ in a computer operating system becomes a map of where the data for all files are stored
directory
A minidisc recorder ____ record data in sequential order
does not
According to your book, Minidiscs are easier and more flexible than digital workstations or computers using DAW software
false
compact discs produce cleaner sound signals initially but over time they exhibit noise after constant playing
false
Technically speaking, sound is not stored on magnetic audio tape. Sound energy is
first transduced into electrical energy and then those pulses are transduced into magnetic energy
In both analog and digital tape recording, the magnetic field produced by a tape head is called:
flux field
Compact discs utilize which of the following technologies to collect information for playback?
laser beam to read information encoded on disc
Compression schemes that reduce the size of audio files by the largest amount use ____ compression
lossy
Which of the following statements about the minidisc is false?
minidiscs received wide consumer acceptance
The MP3 recording system stores ___ audio material on a CD-R disc than the standard compact disc (CD) audio system
more
The standard commercial compact disc (CD-DA) format is
one that can playback but cannot be edited
The MP3 format files compresses a music sound-file using a mathematical modeling system known as
perceptual noise shaping
DAT machines use a method of recording called
pulse code modulation
As the samples of the audio signal's waveform are taken they are converted into binary numbers in a process called:
quantization
R-DAT machines use ____ heads to imprint magnetic pulses on audio tape.
rotating
___ is the process of converting analog audio signals into numerical representations
sampling
The purpose of data error correction in the recording process is:
to minimize the potential for problems that can arise while computers store or retrieve audio data
A device called a __________ in a hard disk is an electromagnet that converts electrical energy into magnetic energy and vice versa.
translator
CD-R, CD-RW, and DVD-R technology uses a laser to heat up or burn the light sensitive layer into a series of reflective and non-reflective areas.
true
Computer disk drive recording occurs when the head's magnetic flux leaves a magnetic imprint in the disk.
true
Digital recording means using samples of sound to produce a recording that is stored in computer language.
true
In order to reproduce accurate sound, the sampling of an audio must include both frequency and amplitude
true
In the playback process, the user can access information stored on a hard disk as the disk's heads retrieve appropriate data and send the data to the computer's random access memory.
true
Radio stations frequently produce commercials in a production studio and then transfer files to digital cart machines using a file transfer program for on-air playback
true
The specific location on the magnetic tape where audio data is recorded is called a track.
true
According to your book, the sampling frequency is approximately ___ than the highest frequencies humans can hear
two times higher
ESPN Radio or other network music services are generally distributed to radio stations
via satellites
