@Justin Xu,
More seriously you make an incorrect assumption here
Quote:every sound around her can be equalled to a specific note in music
Not true specific frequencies can be 'equalled' to a specific note - but frequencies between those specific frequencies CAN NOT be 'equalled' to a specific (western) note
C 4: 261.63 Hz
C 4 sharp (or D 4 flat): 277.18 Hz
D 4: 293.66 Hz
D 4 sharp (or E 4 flat): 311.13 Hz
E 4: 329.63 Hz
F 4: 349.23 Hz
F 4 sharp (or G 4 flat): 369.99 Hz
G 4: 392 Hz
G 4 sharp (or A 4 flat): 415.3 Hz
A 4: 440 Hz
A 4 sharp (or B 4 flat): 466.16 Hz
B 4: 493.88 Hz
An F# is around 370 hertz
An G# is around 415 hertz
'Just south' means 'just below' or 'a little lower' - therefore she is saying that the laptop's frequency isn't quite high enough to be be called a G#, maybe around 400-410 hertz for example.
