Pro Tools 101 Review Questions with correct
answers


Name and describe five types of production tasks that Pro Tools can be used for
- CORRECT ANSWERS ✔✔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? - CORRECT ANSWERS
✔✔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? - CORRECT ANSWERS
✔✔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? - CORRECT ANSWERS ✔✔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? - CORRECT ANSWERS ✔✔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? - CORRECT
ANSWERS ✔✔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? - CORRECT ANSWERS
✔✔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 standard Pro Tools
software. - CORRECT ANSWERS ✔✔Pro Tools | Fast Track family

Pro Tools | Mbox family

Pro Tools | Eleven Rack



Name some audio interfaces that are compatible with Pro Tools HD software. -
CORRECT ANSWERS ✔✔HD OMNI

HD I/O

HD MADI



Name some of the folders and files that Pro Tools creates as part of the session
hierarchy. Where is the session file (.ptx) stored? - CORRECT ANSWERS
✔✔Pro Tools Session > Pro Tools Session.ptx - WaveCache.wfm - Audio Files -
Bounced Files - Clip Groups - Session File Backups - Video Files

The session file.ptx is stored inside the session folder of the same name



What is the WaveCache.wfm file used for? What happens if the WaveCache file
gets deleted or goes missing? - CORRECT ANSWERS ✔✔Stores all waveform
display data for audio in the session

The session may open more slowly if the WaveCache file gets deleted or goes
missing
