Chorus effect explains the out-of-tune shift, not rocket science
What is omitted here is that when the sound frequency shifts down, it does not go directly in tune at the new frequency, but it stays slightly *out of phase* (out of tune, with additional harmonics added in) until the new frequency finally stabilizes, after additional harmonic frequency overtones are finally *removed* and a single frequency plays.
I have programmed an array of analogue synthesizer and digital synthesizer sounds.
The *out of coherence* visual jumble you see here is caused by *additional* and slightly out of tune frequency harmonics added to the fundamental frequency.
Essentially a “Chorus” effect, which is adding in slightly detuned frequencies to the primary frequency, to make the sound “fatter” or “fuller”.
So what you are seeing is the *addition* of slightly detuned frequency harmonics.
I can plainly hear the added harmonics, and can also hear when the added harmonics are removed from the primary frequency.
You can also *see* when the added frequency harmonics are removed.
This is not rocket science.
It’s a basic musical Chorus effect.
Additional added harmonic sound frequencies.
============================
“A chorus effect is a type of audio effect that creates a thicker, more spacious sound by duplicating the original signal and altering its pitch, timing, and amplitude.
It’s commonly used in music production to add depth and richness to vocals, guitars, and other instruments. …”
