[pianotech] Tweaking inharmonicity, was: importing Verituner inharmonicity readings to Excel?

Thank you, that´s what I was looking for. BTW, the Veritune website is down again right now.

The reason why I was looking for that tool: the other day I did an action job on a piano that I had tuned a year ago. I reshaped the hammers, made hammer string mating and seated the strings on the bridge. I was interested if there are any differences in the inharmonicity readings. Do these repairs affect IH? Now I have two Verituner files to compare. But I am not shure if I can answer that question on the base of the given data.

The files contain the *targets* of the partials, not the IH readings itself. The targets are calculated from the IH readings. There could be two reasons for target differences: 1. IH has actually changed  2. one file has more IH readings then the other. Simple example: repair did not change anything, but one file has only IH readings for A3 and A4 and the second file has IH readings for almost every note. So, there might be a difference in the targets just because Verituner has now a broader data base to calculate the targets. Of course I measured many notes during both tunings, but I can´t be shure that the amount of measurements are identical in both cases.

Anyway, I compared both files and there were only slight differences.

www.veritune.com is working at the moment...  including the forum.


 


Answer to Question below:




Quote from Dave C.

http://www.veritune.com/download/VTSyncView/VTSyncView.htm


"It is an unfinished and unsupported program, but it may be able to export a .VOT file into a text file. The exported file contains the partial targets."


This program will make a text file of a .vot file and this can be put in a spreadsheet with all the partials.

Then graphs can be made.

Gregor, 

I was about to to write "Why don't you ask this question on the VeriTuner forum?" but it seems the Veritune website is gone! Anyone know if this is temporary, or permanent?

List,



I know there is a little tool to import VT readings (ppc version) to Excel. How is that tool named and where can I get it?
