Lesson 1 Flashcards
Name and describe the five types of production tasks that Pro Tools can be used for.
Audio, MIDI, Notation, Mixing, Post-Production
When was the first Mbox audio interface introduced? Was this before or after Avid acquired M-Audio?
2002; before
After being acquired by Avid, Wizoo Sound Design became Avid’s Advanced Instrument Research (A.I.R.) group. What types of products does the A.I.R. group specialize in? Give some examples.
plug-ins, and virtual instruments; Hybrid, Strike, Velvet, Structure, and Transfuser virtual instruments
What is the frequency range of human hearing?
20-20,000 kHz
What does the frequency of a sound wave affect in terms of how we perceive the sound? How is frequency measured?
pitch; Hz
What does the amplitude of a sound wave affect? How is amplitude measured?
loudness; 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?
sample rate is the frequency of which these “snapshots” or samples are collected; Nyquist 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?
bits quantify each sample that is taken so the larger binary word lengths quantify amplitude variations with much greater accuracy; multiply bit depth by 6
Give two examples of connections commonly found on audio interfaces, that are used for making digital transfers. What type of jacks does each use?
S/PDIF: RCA (coaxial); AES/EBU: XLR
Name three audio interfaces that are compatible with Pro Tools HD software.
HD OMNI, HD I/O, and HD MADI
Describe some features of the Complete Production Toolkit?
track input functionality for input monitoring on individual tracks, surround mixing up to 7.1 with compatible individual interface, ability to store video files in the Clip List, multiple video tracks in the timeline
