>>798260I think you're misunderstanding the scale at which these webms were made.
Or maybe I'm misunderstanding, in which case I'm sorry.
What happens is exactly like in
>>796458But the input signal is so high in comparison to the carrier that it not only changes the carrier's general amplitude, like in the wiki gif.
I also changes the wave form itself.
An audio signal is already a sort of amplitude modulation on itself. matter moves around at a certain frequency and amplitude.
So what happens when you start adding a similarly fast vibration to the mix?
It changes the overall waveform.
Which means that new frequencies different to both vibrations start to appear.
So let's do this one more time, but this time very very slowly.
Would you agree that the first part of this webm is similar to
>>796458 ?
All I'm doing from then is increasing the tremolo frequency.
And for this carrier signal (a constant 220 Hz), we see interference popping up at ~12 Hz AM.
This experiment goes up to ~1.4 kHz btw.
And sorry for the shitty quality this time.
