Powerballalyzer now available!

[mroek]

As I promised in the other thread, I am now releasing the first beta (although named version 0.1) of my program Powerballalyzer. The program requires no installation, just unzip and run. I've included a couple of sample files for you to try, although I suspect there will be other files you'd want to look at...

There are probably bugs, you can report them to me in this thread or by PM or mail, whichever you prefer. I guarantee that the program does not contain any kind of spyware, and that there are no (intentionally) malicious code in it.

There is a readme file, I suggest you read it. I don't want to repeat all that information here. The only parameter that may be confusing are the "Vanes/spokes". For a regular Powerball, this parameter should be 4. To see why, look at the rotor inside the Powerball...

Used properly, the accuracy should be within just a few RPMs. I've looked at some files, and I suspect that the internal Powerball counter may not always be as accurate as I'd like (especially for very high RPMs), but you can reach your own conclusions.

I've spent a few hours on this, and I'd be grateful for any comments/questions, so if you download the program, please leave a comment in this thread. Maybe it should be called "Threadware"?

And now, without further ado, here's the download link:

Powerballalyzer v 0.4

I've only posted the link in this thread, and it is perhaps best to keep it here for now, and not post the link to other forums?

Edit Obi: File format for WAV input: 11khz, 8bit , Mono >> sometimes you need to convert your video, for avi files, use Virtual Dub.

Edited to change link to the latest version

Yeah let us try it and report bugs before to send it on other forums...

Thank you a lot for your work on this!!


First try on my own record:

Easy to convert it with virtual dub, scan perfectly working, score between 13550 and 13800.

Precision is not of a few Rpms but about the same as the frequency analyser ( on this vid)
But it's far more easier to use and easierto read the score.

I'll go further next week, now I go back to my parents home :/

Here's a screenshot of the program while analyzing the included 10017 RPM file:



As you can see, the peak is pretty close to 10017 RPM...

Great software!!! it measured my score about ~5 or maybe even less rpm precision! if only it would show the scores in realtime! Just wanted to ask... what's gain? i recorder with a microphone and just using sound recorder nice... but once again, would you be able to make it realtime or even 90s strengh index timer with counter this software will lead you to success in powerballs and i really do think you should upgrade it even more

Increase the gain and you increase the resulting image contrast. If you have trouble seeing the curve, you can try increasing the gain. It will not skew the measurements, it will only have a visual effect.

The problem with real-time is to be able to discern the Powerball rotational frequency from noise. Remember that for a real-time application the progam will have to do all the work by itself. In the current version you (the user) are using your eyes and experience to aid in finding the correct RPMs.

But who knows, I might experiment with real-time analysis at a later stage...

[donkapone]

Yeah, i figured the gain out later. Mine was clearly seen on 0.3 About the realtime now. Actually, i do code a bit on c++ myself so i really understand the principles of making everything automatically and how it would be hard. But i thought that it may be accomplished by drawing a nice, solid curve on the main line (didn`t figure it out how it could be done). The curve, of course, should be a little smoother (feathered). Then finding maximums and minimums and displaying just them, because it wouldn`t be able to update very very fast. Well, realtime option is worth a try, and quite a challenge. And i know programmers, because i`m the one itself a little - they love challenges. Good luck if you`ll try making something.

I did everything according to instructions in the readme file, but I constantly get an "Cannot open file" error when dragging and dropping one.

What am I doing wrong?

Just in case The Force you didn`t notice or accidently missed it - the sound file has to be .wav PCM 11025Hz, 8bit, Mono. Just double check it

Sorry but I am using YOUR files for this now. So, i assume that these are correct or not?

And the error I get is "File open error"

What a nice program !!
don't know if i'm lucky but it works perfectly with my own videos...
here is the graph of my personal best score (14182):



amazing precision !
good work mroek

Gouidos: you`re not just lucky it really does work quite precisely

Hi there,

The program now works. And apparently it had to do with too long path names.
Cool program.

Best regards,

The Force

I had a limit of 100 character for path/filename, and that's not enough. The next version will accept longer paths/filenames.
