How to decrease the size of the audio file

I am able to record successfully using the microphone of the blackberry through code. However, files that are deployed are .amr files.after a record of say 1 min a 132 k file is made.which is pretty huge J2ME standards

Dere would amount another type of encryption as a .amr making files lighter. What can I do dat if a large no. small files are made instead of one heavy file.

private static final long mtime = 100000;//records for 1min
RecordControl rc;
byte[] data;
public void run()
{
    // TODO Auto-generated method stub

try

    {  Player p = Manager.createPlayer("capture://audio?encoding=amr"); // Player p set to capture audio here
        p.realize();
        rc = (RecordControl)p.getControl("RecordControl");
        ByteArrayOutputStream os = new ByteArrayOutputStream();
        rc.setRecordStream(os);
       /**FileConnection fc = (FileConnection)Connector.open("file:///store/home/user/RecordedFiles/audio1.amr");

        //if(!fc.exists())
        {
            fc.create();
        }

        DataOutputStream  ot= fc.openDataOutputStream();**/

        //rc.setRecordStream(ot);

          rc.startRecord();//starts the recording
          p.start();
          Thread.sleep(MikeApp.mtime);
          rc.commit();
          p.close();
          data = os.toByteArray();
          saveRecordedFile(data);

        if (p != null)
        {
            p.stop();
            p.close();
            p = null;
        }
    }
    catch (IOException e)
    {
        e.printStackTrace();
    }
    catch (MediaException e)
    {
        e.printStackTrace();
    }
    catch (InterruptedException e)
    {
        e. printStackTrace();
    }
    return;

}
public static boolean saveRecordedFile(byte[] data)
{
    try {
        String filePath1 = System.getProperty("fileconn.dir.music");
        String fileName = "Call Recorder(";
        boolean existed = true;

        for (int i = 0; i < Integer.MAX_VALUE; i++)
        {
            try {
                FileConnection fc = (FileConnection) Connector.open(filePath1 + fileName + i + ").amr");

                if (!fc.exists())
                {
                    existed = false;
                }
                fc.close();
                }

            catch (IOException e)
            {
               // Dialog.alert("unable to save");
                return existed;
            }
            if (!existed)
            {
                fileName += i + ").amr";
                filePath1 += fileName;
                break;
            }
        }
        System.out.println(filePath1);
        System.out.println("");
        FileConnection fconn = (FileConnection) javax.microedition.io.Connector .open(filePath1, javax.microedition.io.Connector.READ_WRITE);
        if (fconn.exists())
            fconn.delete();
            fconn.create();

        OutputStream outputStream = fconn.openOutputStream();
        outputStream.write(data);
        outputStream.close();
        fconn.close();
        return true;
    }
    catch (Exception e)
    {
        e.printStackTrace();
    }

I am currently capable of recording using the microphone and a .amr file is created whose recording time is as much is specified in the sleep.
However what I want, is that a new file is created each time after recording for a certain period of time.
Say record1.amr records for 1min.and as soon as the min is on a new file is created.
in this case up until the time uninstall us the application.
could I get a preview

  • How to associate the audio file with progress bar

    Hi all

    I have a case in which I need to associate an audio file with a progress bar. What I want to do is to able to read an audio file that will say "Started process..." "Continuous on" process ends and it is and must be synchronized with the progress bar. Is it possible to do so.

    Please let me know

    Thank you

    Ankit G

    Are you referring to a LabVIEW horizontal/vertical progress bar that basically an integer U8 constantly wrote in it? Is it in a loop as it fills?

    If so, there is a full range that allows you to listen to the signals. As you write the number of your progress at the helm, you can keep control of what the number is (structure of the event or case), and when it hits special values, you play special sounds. Here's a screenshot of this palette.

  • How to decrease the size of the PDF file without reducing the quality and links?

    How to decrease the size of the PDF file without reducing the quality and links?

    Michael and Phil,

    Your ability to reduce the file without diminishing its quality depends on the quality required for their intended use. If these are intended for viewing on screen, then high resolution pictures can be re sampled or changing the resolution without real change is the quality, as long as the user can say. Number of files use subsets of fonts or the incorporations of fonts. Sometimes you can remove subsets of fonts or embedding the fonts if the font will be on the user's system. Subsets of fonts can save space, but if the pdf is a result of several different sources, desincorporation policies and incorporating a copy of the policy can save space.

    Honestly, the size of 2 MB file is not the problem it once was. However, maybe the pdf not by e-mail at all. There are players on a server as well as a link sent to each user.

  • 5102na HP OMEN: how to disable the audio correction Bang &amp; Olufsen horrible?

    Is there someone who could tell me please how to disable the audio correction Bang & Olufsen? I'm sure that some people like it but I work with audio and I can't really how it changes the sound. I tried to open the Bang & Olufsen sign but I cannot unselect the correction in the section "listening experience", nor that I can change the associated equalization. Please someone help, thanks!

    I found a solution: http://h30434.www3.hp.com/t5/Notebook-PC-Sound-and-Audio/Beats-Audio-compression-and-volume-fluctuation-HP-ENVY-m6/m-p/5137867/highlight/true#M67144

    1. Go to the Windows Device Manager > sound, video and game controllers section.
    2. In the list of the audio device drivers, look for Realtek High Definition Audio. This is the device driver for BeatsAudio (a bit sneaky, wouldn't you say?).
    3. Right-click and select disable. Down arrow on this driver, indicating it is disabled. (NOTE: at this point, you will not be able to play music files.)
    4. Right click and select Update driver software.
    5. Select Browse my computer for driver software.
    6. Select Let me pick from a list of drivers for devices on my computer.
    7. You should see a window that says Select the driver to install for this hardware device. NOTE: If you see a window that says something like This is the best driver for this device, close the window and repeat steps 4, 5 and 6.
    8. In the scheme box, select Audio device high definition (this is the device driver audio substitute) and click Next.
    9. In the Update driver warning window, click Yes. You should see a confirmation with the high definition Audio Device display window. Click on Close.
    10. In the list of drivers of audio device in the section audio, video and game controllers, you will notice that the high definition Audio device now displays instead ofHigh Definition Audio Realtek.
    11. When prompted to restart, click Yes.
    12. Now enjoy your music with no compression!

    Thanks to SteveCT99

    This does not disable audio-Bang & Olufsen, but I just installed this EQ across the system instead: http://sourceforge.net/projects/equalizerapo/

    HP needs to release a driver which allow us access to the "Improvements" tab so we can turn off "Loudness equalization" (although "Loudness equalization" should not be on by default in the first place).

    The current driver is default.

  • How to modify the audio appearance when it is in an ePub document?

    Hi all

    I'm integrating audio content in my inDesign file in the "Advanced" design space, which will eventually become a fixed provision ePub file, then an eBook.

    However, when I place the audio file which works fine, I can not understand how to change the appearance of the 'media' window/Panel audio player built into inDesign. If I extend the framework to make it much bigger, a full audio bar (complete with controls), but it is very small. Alternatively, if I do the 60px banner frame by 60px banner, the audio bar is way shorter and apparently cut, but it is bigger and I can actually click on videos.

    Please check if it is all confused! It's a little hard to explain, so anyone with any input would be helpful. Thank you!

    I moved your question to the forum InDesign EPUB.

    You may have more luck if you create buttons to start and stop the audio. You can customize the appearance of the button because you can turn any shape or an object into a button. The Panel of buttons and forms to set up the button controls.
