Hi everyone,

I have a question about HD. I know very well of the
implications of the harmonic series (or overtone series)
in music making and acoustics. My question is: when one
refers to, for example, "second harmonic distortion" in
terms of audio, does "second harmonic" mean the same
thing that it means in music and acoustics, i.e. an
octave plus a perfect fifth above a fundamental?

The second harmonic of a fundamental tone is exactly one octave higher. The
frequency ratio is 2:1.

This is EXACTLY how the terms are used in music; I simply misspoke in my
question. There is evidently NO difference in how the terms are used.
I wrote "second harmonic" when I meant to write "second overtone".
