inharmonicity and intervals calculation

[Alexander Galembo]

Dear list members, 

I would like to ask for information.

Since I was extensively worked in my research projects with synthesis and
analysis of inharmonic tones, I have created, about a year ago, several
interactive sites in my web page for to calculate easily Hertz to cents,
inharmonic partial frequencies, equally tempered intervals in scales with
stretched/compressed octaves, etc.

I have an idea to organize together and to open these sites now - for my
colleagues scientists and for everybody who wants to use them.

I want to evaluate the quality of my sites before to open them,
particularly to compare them with other similar sites, which may exist. I
wonder whether anybody knows any sites in Internet which allow, e.g.

- To find the interval in cents or semitones, knowing the frequency ratio,
and vice versa
- to find the frequency of the particular partial in inharmonic spectrum;
- to find an inharmonicity coefficient value knowing frequencies of two
partials

... etc.

If you met any active web sites like this, please let me know about them,
then I will be able to make my "calculators" more convenient to use before
opening them.

Best wishes,

Alex
