Getting the frequency of a wav file...

Hello..
i am working on a project that needs to identify the frequencies of the sounds in a wav file..
I will sing and record my voice and then identify the frequencies so i can compare it to another wav file and compare these frequencies. I need to detect if the 2nd wav file is still in tune with the 1st wav file...
Is this possible? thank you very much...

Hi,
I don't know much about this subject, but I believe you'll
need some digital signal processing, propably fast fourier
transform to achieve this.
The details are not clear to me, but I think that in this way
you can get the frequency of the signal and then you can
compare it to the frequency of the original signal.
Hope this helps.

How do I get the block duration for wave file playback?

I'm using a LV example "Getting Started with sound and vibration express vi's (simulated). When I play back the examples the audio does not match the graphing updates as the file is played. That is, the sound continues to play after the graphs have finished reading the file. I can change the input box "block duration (s)" to achieve playback coordination between graph updates and audio. Is it possible to calculate this value from data included in the file? If not then if I have a vi that records sound to a wav file could the "block duration" be calculated there and passed to the playback vi? Just not sure what makes up the block duration. Thanks

Hi Mike,
The Block Duration that is configured from the Front Panel is a control that is used to determine how much of the sound file has the analysis performed. From the Block Diagram the Block Duration control is used to calculate the subset of the Get Waveform Subset.vi. Also notice the sound file is opened prior to entering the case structure, thus will begin first to execute due to dataflow. This may be easier to see using highlight execution. The sound VIs are not affected by the Block Duration at all as the entire sound file will be played. Take the data from your sound file and display it onto a chart or begin processing as in the Read Sound File to Chart.vi example for immediate updates Hopefully this helps!

How can we get the artset from a .ai file without opening it?

Hello All,
I have one .ai file, lets say sample.ai file. located in C drive. so the complete file path is "C:\Sample.ai".
and lets assume the sample.ai file has one traingle shape(3 path type arts) in it.
Now I want to get the 3 path arts (artset) from sample.ai file without opening it in AI.
The function protoype is like below
AIArtSet& artSet GetArtSetFromAFile( ai::FilePath& filePath );
Is there any API like above function in AI? or is it possible to get the art(s) from a file without opening it in AI?

Not to my knowlege. The API only operates on active documents as far as I know.

How to get the Real Path of a file which is accessed by URL?

iam using tomcat6.0.
I have a file xyz.xml at the top of the webapplication HFUSE which i can able to access by URL
http://localhost:8080/HFUSE/xyz.xml
My problem is how to get the realpath of the file "xyz.xml" for reading and writing purposes.
I tried various things but i could not able to successfully solved the problem?
1) File f = new File("/xyz.xml");
print(f.getAbsolutePath()) ============== it is not fetching the file @ http://localhost:8080/HFUSE/xyz.xml rather it is creating a file
at the root of the drive where eclipse is running.
2) File f = new File("xyz.xml");============> this is also not working , it is creating the file xyz.xml in the eclipse directory ..................
Can anyone please guide on this problem?

If you want your context root(i.e HFUSE)
use this:
request.getContextPath() //where request is HttpServletRequest object to get the needful path.
e.g:
File f = new File(request.getContextPath()+"/xyz.xml");//it will create the file inside HFUSE.
Hope this helps.

BWrong. The File constructor expects an absolute filesystem path. The HttpServletRequest#getContextPath() doesn't return the absolute filesystem path, it only returns the relative path from the current context root. Use ServletContext#getRealPath() instead, it returns the absolute filesystem path for the given relative path from the current context root.
File file = new File(servletContext.getRealPath("/"), "xyz.xml");

To upload the ZIP file and get the filenames available in ZIP file in ABAP

1. Copy the ZIP file into App server

call function 'RFC_REMOTE_PIPE'
    destination 'SERVER_EXEC'
    exporting
      command = command " Unzip command gunzip /path & file

I keep getting the error message "Missing PDFMaker files. Do you want to run the installer in repair mode"

I keep getting the error message "Missing PDFMaker files Do you want to run the installer in repair mode"when I try to convert a file into a pdf. I have tried uninstalling then reinstalling but I continue to get the message. I am able directly print file, but there are some errors in the pages, but some of them have font errors. Please advise.

Hey Suzanne,
Could you please let me know what Acrobat version are you using and what kind of file are you trying to convert to PDF.
If you are using an MS Office application, then PDF Maker has to be an active plug-in for the PDF conversion.
Have you tried using Print to PDF option from the File menu for the same?
Please check and then let me know.

How to get the encoding of a XML file ...

Hi,
How do you get the encoding of a XML file?
For example,
<?xml version="1.0" encoding="SJIS"?>
I am trying to retrieve the above encoding="SJIS", but I can't seem to locate the API for doing so.
Thanks in advance for any help,
Eric

Hi ddossot,
Thanks for your suggestion.
However, the xerces.jar file that comes with my old tomcat server is an old version and thus, the getEncoding method is not even present in the DocumentImpl class. The option to update to a newer version of tomcat and xerces is not available. What a pity... :-(
Well, I just have to try to find a way around. Worst case scenario, parse the first line in the xml file myself.
Regards,
Eric

How to get the length of a audio file without play it ?

Now I know a method to get the length of a audio file by play it:
1 Create a Player, and add a ControllerListener
2.Start the Player
3.In the ControllerListener's controllerUpdate method, use getMediaTime() by receiving a EndOfMediaEvent
However I think this method is not convenience, if I don't want to play it how I can get the length of the audio file?
Is anyone can help me?Really thanks a lot !

I got the answer here:
http://forum.java.sun.com/thread.jspa?threadID=5149132&tstart=15
I tried getDuration() before, but it always return a same time, I think maybe I didn't realize the player.

Terminal how can i get the picture dimension of a file?

Is it possible to get the dimension of an picture (120 x 120 px) via terminal command? The information is visible under the finder "getinfo" command for picture files. Can anyone help?

You can get image pixel size info using the ImageMagick utilities, which is a GNU package available for installation via the fink pacakage manager, then you can use the terminal command:
identify image.gif
ImageMagick also has several other useful conversion and image processing utilities.
http://www.finkproject.org/
http://www.imagemagick.org/script/index.php
Good luck.
P.S. - There may be ways to interact with AppleScript from Terminal to get the Finder info from a file, but I don't know how to do that.

In Mac how to get the Full name of a file Programmatically?

Hi Friends,
I am doing one Mac application for displaying the contents of a file. I can able to get some information about the file by using this code below...
NSDictionary *dict=[fileManager attributesOfItemAtPath:myPath error:nil];
Now I want to get the some other informations also like Full Name, copyRight, version... So Please suggest me how to get the full name of a file Programmaticallly?

Your question doesn't make sense.
First off, if you are going to get the attributes of a file, you need its full name before you can do anything. So that's part one taken care of.
This function returns a dictionary full of typical file information (type, size, mod dates, etc.) as well as some HFS data (creator code, type code) which, I strongly suspect, are not "pulled out of the file" but rather generated on the spot. (See NSFileManager for the full list of attribute keys.)
The other items you hoped of retrieving are not part of the regular file system. Sure, a Truetype font has a copyright string and a version, but what about an HTML file? A PNG? A text file you just created?
There simply are no standard functions to retrieve copyright and version.
