Audio Freqency
What a mundane song, it’s just the same note repeated over and over. But could there perhaps be two different notes?
Solution
As I zoomed into their waveforms, I see two different waves, which possibly means binary.
I verified that by looking at the first and last character. If they represent “f” and “}” in binary, then that validates my theory.
Longer wavelength = 0 ; shorter wavelength = 1.
Yes, “slight” was misspelled, but that was the correct flag.
