| that's a very big question!
i'm not qualified to answer your questions but i imagine they definitely have harmonics in their sound with several fundamentals and harmonics in the attack portion.
the only sound that doesn't have harmonics would be a digitally created sine wave but as soon as it's out of your speakers or even before it's out of your speakers and interacted with components, wall, furniture, etc it will have harmonics
even digital to analog converters can add harmonics to the signal
but really, i'm not qualified at all to answer this (other than my experience) and maybe my above hypothesis is even incorrect but hey, who knows!
good luck |
