101 Chapter 1

Question 1

Name and describe five types of production tasks that Pro Tools can be used for.

Answer 1

Audio Processing
MIDI Production
Notation and Scores
Mixing and Automation
Audio for Video and Post-Production

Question 2

What is the frequency range of human hearing?

Answer 2

22,050 Hz

Question 3

What does the frequency of a sound wave affect in terms of how we perceive the sound? How is frequency measured?

Answer 3

The Pitch. Measured in cycles per second (CPS), also commonly denoted as Hertz (Hz)

Question 4

What does the amplitude of the sound wave affect? How is amplitude measured?

Answer 4

The Intensity of a SoundThe Intensity of a Sound

Measured in decibels (dB)

Question 5

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?

Answer 5

Nyquist Theorem: Sample each cycle at least twice to capture the audio frequency.

Question 6

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?

Answer 6

Number of binary digits used to represent each sample; determines accuracy of measurements. Larger bit depths provide more dynamic range.
To estimate dynamic range, multiply bit depth by 6.

Question 7

What are some common digital connections available on Pro Tools audio interfaces? What type of connector jack does each use?

Answer 7

S/PDIF uses RCA also called Coax

AES/EBU which uses XLR-type connectors
