Everything I have up to 1/31/23

Question 1

oscillation

Answer 1

movement back and forth at a regular speed

Question 2

Pitch

Answer 2

the quality of a sound governed by the rate of vibrations producing it; the degree of highness and lowness of a tone

Question 3

Timbre

Answer 3

Generally refers to the quality of a sound by a particular voice or instrument; Timbre is useful in being distinct from pitch, intensity and loudness as a descriptor of sound. Harmonies help shape an instruments timbre.

Question 4

Formants

Answer 4

Are frequency peaks in the spectrum which have a high degree of energy. Formant Frequencies are essentially resonance frequencies of a vocal track. These frequencies vary among different persons and words.
