How to display audio file as a graph?

Hi all,
I m creating a swing application for processing audio file.
In that application, i want to display audio in wave format.
my requirements are
*1. It should support all common audio file formats.*
*2. zooming (scaling) of graph with respect to time should be possible*
Please help me in doing this.
Can anyone suggest any api for that?(if it is better to use some api)
thanks in advance.

JavaZoom's API does: [http://www.javazoom.net/projects.html]
3rd party libraries and plugins do lots of stuff, sure. But this is a JavaSound forum, after all...
For mp3 files, audioInputStream.getFrameLength() is -1.(this code requires that for creating graph).
So how to solve this?The existence of JavaZoom doesn't change the fact that "no one solved it", because JavaSound doesn't support MP3 files... So JavaZoom isn't going to change the results of audioInputStream.getFrameLength() for an MP3 file.
So, in conclusion... If you want to play an MP3 file, JavaZoom will do that. But if you want to +"solve it"+ then you're still SOL ;-)

    You can't really.
    You need to use DHTML in the swf-wrapper HTML file, usually a
    division wrapped iFrame, and load the PDF into the iFrame as an
    overlay to the Flash.

  • How to display Doc file format in the JEditPane?

    At this time , JEditPane supports RTF and HTML file format ,but
    Could anyone tell me how to display DOC file format using JEditPane
    or other JTextComponents?
    Thx a lot!
    Caton

    Hi,
    there is no support for doc files (M$ Word?) in Java. You would have to create your own classes for that eventually subclassing JEditorPane, EditorKit, Document etc. As well you'd need your own reader for the doc format.
    The problem I see with that however is that there is nothing such as thedoc file format. Microsoft just saves anything produced by MS Word into files ending with .doc. But, if there is anything such as a .doc file format, it changes more often than the weather in April.

  • How to display XSL file to ASPX in dreamweaver

    Hi,
    Just wondering how to display XSL file in ASPX page?
    I normally do it in ASP page by using server behaviour XSLT transformation and bind it to ASP page and this works very well.
    Now I am trying to use the same method and using ASPX page this time but this time there is no option from server behaviour where I can bind it to my ASPX.
    Can someone help or perhaps let me know where I can find the information how to do it?
    Thanks,
    Rush O

    You mean you want to see the XML source?
    You need to replace the characters '<' and '&' with corresponding entities '&lt;' and '&amp;'. You can use replaceAll, but do the ampersands first.
    Then I suggest you probably want to put them in a <PRE> block.

  • How to display audio (wav) files as a graph?

    Hi,
    I am building a Java Swing application that will play wav audio files and have a requirement to also DISPLAY the waveform as a graph (amplitude vs time).
    I have been using some basic java sound methods to play the audio but was hoping that there might be some code out there to also DISPLAY the waveform.
    Capability to zoom in and out would be nice also, but any help to simply display a wav file would be great. If it makes any difference the wav files are encoded PCM at 8,16, and 32 kHz sample rates.
    I am a novice java programmer (but learning fast)....
    Thanks. Bill

  • How to display the file contents???

    Hi all,
    I have a JSP page which is suppose to display resource contents on clicking of href like this:
    <td><a href="">Click here</td>But the problem is, these contents are stored some where on the hard disk of the system inside the folder \\LMS\Resources\doc\knowledge.doc.
    some other file I have like:
    \\LMS\Resources\pdf\display.pdf
    It can be any file (PDF,DOC,SOUND AUDIO).
    Can anyone please tell me how to open the contents of the file directly from href???
    Or I should use some other way to display those files.??I just want a way to start with.......
    Thanks in advance
    Namrata

    Hello Namrata,
    There are millions of ways to do this.
    1. You can create a shared drive in your server as "\\LMS\Resources" pointing to K Drive etc... You can write a simple servlet which picks up the relative path from "\\LMS\Resources" which is "pdf\display.pdf" and it can read the file and then based on the file extension it can resend the response mime type for the browser to pick it up. This can be done in both Windows and Unix environments.
    2. Have a Content Management System like Lotus Domino, Fatwire, etc and upload all contents and point the href to the Content Management System URL.
    3. You can upload the documents into a database as BLOB data and then use it to render content.
    4. You can also have a regular program which synchronizes the data from \\LMS into the Server hardware in a particular location.
    In Options 1, 3, 4 you need the servlet to render the content out to the Client browser.
    All this can be done based on the Technology environment, cost available to spend, Skill sets available and other factors.
    Do let me know if you need any more information
    Thanks,

  • How to display HTML file from Unix server on UI at runtime

    Hi Experts,
    My requirement is to display  HTML files,  related to some particular person, on UI. The file is existing on a separate UNIX server and a file related to one person may have a lot of attached files as well , as is the case generally with HTML files, including pictures etc. So it is no use transferring file on my CRM system, as the files are kept separately on this UNIX server which is particularly for this kind of storage.
    I am able to show files residing on MIME repository ( I created some new HTML files )  of my CRM system on UI. but I don't know how to go ahead with this particular requirement.
    One idea is that I can map one folder of my application server to that unix server so that I can see the HTML files in this particular folder. but I don't know how to map MIME repository folder to application server directory or directly to the UNIX server .
    Please advise. Is my approach correct or is there any other way ?
    thanks in advance.
    Regards,
    Vikas

    Maybe this is too simple, but have you got an HTTP server on the UNIX machine? You could simply link the URL into you CRM application and display the contents directly from UNIX.
