SECTION 1

Question 1

Name and describe 5 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 & Post Production

Question 2

What is the frequency range of human hearing?

Answer 2

20hZ to 20kHz

Question 3

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

Answer 3

The frequency of a sound defines it’s perceived pitch. This is measured in hZ and kHz.

Question 4

What does the amplitude of a sound wave effect? How is this measured?

Answer 4

The amplitude of a sound defines its perceived volume. This is measured in decibels.

Question 5

How does the sample rate of a system relate to the frequency of the audio it can capture?

What is the name of the law that specifies the relationship between sample rate and audio frequency?

Answer 5

The sample rate is the frequency with which digital measurements of an electrical signal are recorded - the higher the sample rate, the better quality the capture.

Sampling Theorem / Nyquist Theorem

Question 6

How does the bit depth of a system relate to the dynamic range of the audio it can capture?

How can you estimate the dynamic range of a system?

Answer 6

Bit depth is the number of binary digits used to record each sample. Higher bit depths allow for more dynamic range.

Multiply by 6.

Question 7

What are some common digital connections available on Pro Tools audio interfaces?

Answer 7

S/PDIF - RCA
AES/EBU - XLR
MADI - Optical
MADI - Coaxial
