Sampling rate - answer- the frequency with which numbers are stored or written down to

sampling rate relate to playback quality?
, Nyquist frequency - answer- The highest frequency the can be reproduced- or the
highest sampling rate

period sound
Time domain - answer- a waveform represents sound directly, air pressure changes
over time
FFT spectrum - answer- -clearly shows harmonic energy

Vocal modulation - answer- rhythmic changes that are predictable in fundamental
frequency and in amplitude in the voice; gradual increases and decreases that occur
over the course of many glottal cycles
