ProTools 101 Certification Study Guide with complete questions and answers

Name and describe five types of production tasks that Pro Tools can be used for. (The Pro Tools Digital Audio Workstation, p4) Audio Processing, MIDI Production, Notation and Scores, Mixing and Automation, Audio for Video Post-Production What is the frequency range of human hearing? (Audio Basic: Waveform, Frequency, and Amplitude, p10) 20hz to 20khz What does the frequency of a sound wave affect in terms of how we perceive the sound? How is frequency measured? (Audio Basic: Waveform, Frequency, and Amplitude, p10) Pitch In cycles per second (hz or khz), or samples per second. What does the amplitude of a sound wave affect? How is amplitude measured? (Audio Basic: Waveform, Frequency, and Amplitude, p10) Perceived volume In decibels 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 Importance of Sample Rate, p11) To capture pitch accurately, you must sample at twice the highest frequency for a minimally accurate representation of the wave. Nyquist Theorem, typically pitch is sampled at 44.1 and up because human hearing goes to 20khz. 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 importance of Bit Depth, p12) Six db per bit, 16 bit = 96 db (16*6), 24 bit = 144 db (24*6) What are some common digital connections available on Pro Tools audio interfaces? What type of connector jack does each use? (Recording in Digital Format, p13) S/PDIF, uses RCA jacks (also called coaxial jacks) AES/EBU uses XLR-type connectors [preferred all things equal]
