Very interesting, since the artificial “ghost” note is at a lower frequency, would they essentially become an “undertone” ?

- TylerE 6y agoNo, not really. The fundamental is always the lowest frequency. All overtones are some (almost always integer, or _nearly_ integer) multiple of that.
- ttt0 6y agoUndertone is something different, but I never explored that concept and what could it be useful for, so I can't really explain it Not an undertone, it's fundamental frequency. Harmonics/overtones follow a very specific pattern: https://en.wikipedia.org/wiki/Harmonic_series_(music) https://en.wikipedia.org/wiki/Harmonic_series_(music) ...so in most cases there isn't really any ambiguity on what the actual fundamental frequency is. The best way to demonstrate it is probably with a high-pass filter (aka. low-cut filter). High-pass filter allows only higher frequencies to pass through, or in other words it cuts out lower frequencies. On the example below you can hear that as the lower frequencies are getting removed from the signal, it's still the same note: https://www.youtube.com/watch?v=50lRE2Bgag0 https://www.youtube.com/watch?v=50lRE2Bgag0 I wish the filter sweeps were slower, but that's the best example I could find
