1. The file format that uses a shorthand representation of musical notes and durations stored in numeric form is:

a.       AIFF

b.      CD-ROM/XA

c.       DSP

d.      MIDI

e.       QuickTime

  1. Which of these statements regarding the MIDI audio format is not true?

a.       The sound can easily be changed by changing instruments.

b.      Spoken audio can easily be included.

c.       Sound tracks can be created using sequencing software.

d.      Files are generally smaller than the same digital audio sound.

e.       Sounds can be stretched and timing changed with no distortion of the quality.

  1. The primary benefit of the General MIDI over the previous MIDI specification is that:

a.       the file sizes are much smaller due to the compression scheme

b.      users can easily edit and adjust the data structures

c.       it can be easily converted into the CD-ROM/XA format

d.      MIDI files can be easily integrated into the computer’s operating system as system sounds.

e.       the instruments are the same regardless of the playback source.

  1. What happens when an audio signal exceeds the recording device’s maximum recording level?

a.       The signal is compressed to an appropriate level.

b.      ”Clipping” of the signal occurs, introducing distortion.

c.       The audio clip is extended to accommodate the extra data.

d.      The entire clip’s volume is reduced correspondingly.

e.       The extra bits go into a buffer for later use.

  1. As one story goes, the criterion used to set the length of the sectors and ultimately the physical size of the compact disc format was based on the length of:

a.       the Beatles’ “White Album”

b.      Handel’s Messiah

c.       Beethoven’s Ninth Symphony

d.      Bach’s St. John’s Passion

e.       Iron Butterfly’s live rendition of “Innagaddadavida”

  1. The process of recording a sound, stored in the form of thousands of individual measurements, each at a discrete point in time, is called:

a.       sampling

b.      synthesizing

c.       sizing

d.      quantizing

e.       streaming

  1. The file size of a 5-second recording sampled at 22 kHz, 16-bit stereo (two tracks) would be about:

a.       110,000 bytes

b.      220,000 bytes

c.       440,000 bytes

d.      550,000 bytes

e.       880,000 bytes

  1. Which of the following sound file characteristics does not directly affect the size of a digital audio file?

a.       sample rate

b.      sample size

c.       tracks (stereo vs. mono)

d.      volume

e.       compression

  1. Each individual measurement of a sound that is stored as digital information is called a:

a.       buffer

b.      stream

c.       capture

d.      sample

e.       byte

  1. Audio recorded at 44.1 kHz (kilohertz), 16-bit stereo is considered:

a.   phone-quality

b.      voice-quality

c.       FM -quality

d.      CD-quality

e.       AM-quality

  1. Removing blank space or “dead air” at the beginning or end of a recording is sometimes called:

a.       quieting

b.      pre-rolling

c.       quantizing

d.      trimming

e.       flashing

  1. DSP stands for:

a.       dynamic sound programming

b.      data a structuring parameters

c.       direct splicing and partitioning

d.      delayed streaming playback

e.       digital signal processing

13.  Sequencing software:

a.       places audio clips in order in a sound track

b.      records and edits MIDI data

c.       applies filters to digital audio clips in a predetermined order

d.      manages a project by creating a timeline of events

e.       helps synchronize images with a sound track

  1. The slower a user’s connection, the longer he or she must wait for enough of the sound to download so that the entire file will have downloaded by the time the sound reaches the end. This effect is called:

a.       streaming latency

b.      post-processing

c.       compression

d.      digital signal processing

e.       multitap delay
