Pro Tools 101 Review Questions| Answered 100% Correctly
Name and describe five types of production tasks that Pro Tools can be used for
Audio Processing: recording of audio performances and stores them as files.
Works with audio that is stored electronically in digital format
MIDI Production: record and edit MIDI data. Captures performance event data.
Devices are involved.
Notation and Scores: ways to display and work with MIDI compositions in music
notation and printing capabilities.
Mixing and Automation: Controls signal routing, effects processing, signal levels,
panning, etc...
Audio for Video Post-Production: Import QuickTime movies or Avid video files
and add audio sound effects, music, Foley, and dialog.
What is the frequency range of human hearing?
20Hz to 20kHz - 1kHz = 1000Hz
What does the frequency of a sound wave affect in terms of how we perceive the
sound? How is frequency measured?
Frequency of a sound wave affects the pitch that we hear. The higher the
Frequency number, the higher the pitch. Frequency is measured in either cycles per
second (CPS), or Hertz (Hz). - 15000CPS = 15000Hz = 15kHz
What does the amplitude of the sound wave affect? How is amplitude measured?
Amplitude of the sound wave affects how loud it is. The higher the Amplitude, the
louder the sound. Amplitude is measured in decibels (dB)
How does the sample rate of a system relate to the frequency of audio it can
capture? What is the name of the law that specifies the relationship between
sample rate and audio frequency?
The higher the sample rate the more accurate representation to the frequency of
audio(sound). More sample rates = less chance for misrepresentation of audio
clips/wrong tones. The law that specifies the relationship between sample rate and
audio frequency is Nyquist Theorem or Sampling Theorem.
How does the bit depth of a system relate to the dynamic range of audio it can
capture? How can you estimate the dynamic range of a system?
The bit depth is the binary word length of a "sample". In order to know the
dynamic range of a "system", you would need to know the bit depth. You can
estimate the dynamic range of a system by multiplying the bit depth by 6. An 8-bit
binary word x 6 = 48dB.
What are some common digital connections available on Pro Tools audio
interfaces? What type of connector jack does each use?
S/PDIF (Sony/Philips Digital Interface = RCA jacks(coaxial jacks)
AES/EBU (Audio Engineering Society/European Broadcast Union) = XLR-type
connectors.

Name some audio interfaces that are compatible with Pro Tools HD software.

Name some of the folders and files that Pro Tools creates as part of the session
hierarchy. Where is the session file (.ptx) stored?
