AVID PT 101 EXAM ACTUAL UPDATED QUESTIONS AND CORRECT ANSWERS
Waveform refers to the shape of sound
Compression Phase of a Waveform energy going up and then coming back down
Rarefaction Phase of a Waveform energy dropping below the zero line and return to the zero line
, How is tone/timbre represented in a waveform? By the shape
Frequency refers to the pitch of a sound
A cycle is one period of compression followed by one period of rarefaction
Hertz (Hz) cycles per second; measure of frequency
Amplitude refers to the intensity of a sound wave
Decibel (dB) a unit of amplitude
Dynamic Range range of amplitude/decibels
Analog to Digital when audio is recorded to a digital medium
Digital to Analog when audio is played back
Sample Rate the number of samples used per second
The Nyquist-Shannon sampling theorem states that in twice the highest frequency of that sound.
order to accurately record or reproduce a sound, the
sample rate must be at least
Foldback or aliasing when an incorrect sampling rate is used to record audio
