Tony, there is a lot there but let’s start with the graphs of fundamental tones from an organ and how they change into different "instruments" as the pattern of harmonics change. That looked a lot like measures of harmonic distortion from amps and other devices. It explains why harmonic distortion, say from tubes, is not always a bad thing, our hearing is just receiving a different timbre. Also that "diistorion" per se is not a unique product of hifi systems, it is really inherent in all music. We are very accustomed to low order harmonic distortion because it is "natural". Good stuff, thanks!
How we hear.
Veritasium is always interesting, but I thought this one might be of special interest to our group.
I am not offering my opinion at this point. I am more interested in seeing what other people found interesting and what conclusions or connections you made.
