Small update: VeriTune has filed a DMCA takedown notice with Sourceforge, leading to the current unavailability of the project -- I will try to resolve this with SourceForge, but if unsuccessful, I will host it myself in another country, which will make it impervious to any future DMCA requests.

It is really bothersome that the DMCA gives rightsholders so much power in the US...

I think Pisarenko's method (or some variant) is what you want.

There is probably a US patent on scratching your head. Shame on Verituner.

Filiptb - sorry to hear about your troubles with VeriTune.

I'm sure they weren't happy to see a substitute product that is free. And free is certainly a lot cheaper than the $900 that they charge (robbery if you ask me) so they are probably just afraid of a little competition.

I wonder if Veritune has any patents at all, or they just filed the DMCA complaint to try and stop a competitor. As the Apple vs. Microsoft case shows, you can't patent a software interface, you can only patent the code behind it. Unless you somehow got your hands on their actual source code and copied it, I don't really think Veritune has any kind legitimate complaint.

If Veritune can't compete with one guy writing his own open-source software project, what hope do they have in competing against Tunelab (which has a better product for 1/3 the cost, in my opinion) and Reyburn Cyber Tuner? I think their DMCA complaint speaks volumes about their insecurity regarding how good they think their software actually is, and what they think about their ability to compete in the marketplace.

Thanks for standing up to them and continuing the development of UltraTune. It has a lot of potential to be a great piece of software (actually it already is!).

I think I found the solution:

Noteworthy that not one tuning program like Verituner (or any of the others for that matter) has made it to "market," free or otherwise. I wonder whether it is that easy to smash the copyright?

Anyhow, Verituner is highly regarded--probably the most highly regarded piano-tuning software for a number of reasons, not least of which is the "spinner," which can be speed-adjusted in a manner that makes tuning a string after the initial attack (hammer blow) both flexible and at the same time very, very accurate.

Also, of course, VT permits complex, user-defined tuning styles.

Is it vulnerable? Susceptible of improvement? Absolutely! It is cumbersome, to say the least, by current software standards.

This paper describes a method in section 3.1. Resolution is something like 0.0001 cent in the absense of noise. It also extracts decay rates and amplitudes.

Hello filiptb,

I have 2 questions:

Ultimately, do you plan to make your UltraTune multi-partial?

Since you are going FOSS, any plans for a GNU/Linux version?

Thanks,

I think that the EU has implemented the DMCA so it is the same within the EU as in the US.
I don't understand the problem though. If someone create something like a software or whatever, why should they upload it or parts of it for free? They might have spent a lot of time on their projects, and want to get paid for that, just like we all want to get paid for our work.

What does Verituner's DMCA takedown notice claim? Is the document publically available?

Patent search comes up with this:

Carpenter tuning patents

A couple of these are not related. They just happen to have the word "tuning" in the abstract.

Haven't waded through it all yet. Patent language is a bit convoluted (well, more than a bit).

I find that pianos prevent me from attaining a perfect tning.....

Why would you want to tune your windows?

Internet economic model (I mean Google, to simplify) is not adapted to traditional artisanal work as piano tuning, repair, etc.

I cannot see how I could tune your piano at distance, and being paid by Google ads.

Then I could do 5 "virtual" tunings a day, but the physical expense would remain. ( I heard that the Hollandese tuners syndicate had negotiated with piano shop owners so not to do more than 6 tunings a day !)

xx wrong thread

From now on, UltraTune can be found at http://www.ultratune.nl.

Will the program run on Mac, or Windows only?

Thanks,
jw

The program is currently Windows-only. I am not currently planning on creating a version for Mac. My goal is to make it on par with the commercial programs. When I accomplish that goal, I will try to go cross-platform (but probably starting with Android first).

Unfortunately I do not own a Mac which makes developing for that platform currently impossible.

Of course, since the program is open source, you are free to try and port the code to make a Mac version yourself.

Thanks! I have a PC to put it on, but since my work laptop is a mac and much newer I thought I'd ask. Thanks for the suggestion on modifying the software- I'm doing well to just run the computer without hurting myself, so I better pass on any code work!

Cool thing you're doing here!
John

OhZZZZ.

Hi Weiyan,

If you look at my first post, you will see that I updated Windows and then updated DirectX. After that, it started working.
