A Small Equation = inharmonicity??

[Don]

Hi Michael,

So you can set it to 0.1 of a hertz, or ??? At A4 440 to 441 is just about
4 cents. I don't have TLA but have used a Sanderson Accu Tuner, and
currently use Reyburn Cyber Tuner. Both share the specification for
accuracy that I mentioned from the SAT site. Both of them use a "band pass
filter" so only listen to a particular partial of a particular note.

The limits of aural testing verge on 1/10 of one cent. For unisons it is a
whole different ball game. You might wish to search the archives for
"coupled motion of piano strings".

I'm not a Verituner user, so can not speak to what it offers from any hands
on knowledge, but it is my understanding that it listens to several
"partials" of a single note and displays them in real time on a spinner by
using a Digital Sound Processing Chip.
