How read/write matlab style WAV sound file?

The supplied LabVIEW WAV read/write VIs require fixed sampling rates (like 8000, 11025, 22050, 44100), and use integer data (so the waveforms take on large +/- integer values).
I need to read/write WAV files that are like those used in Matlab with its wavread and wavwrite functions. Those can use ANY sample rate, and the waveforms have decimal values between -1 and +1.
Could someone suggest either how to directly write these standard WAV files with an existing VI, or how to write my own VI to do this?
Thanks in advance.

That's a great help! Thanks. I have made the changes to the supplied NI VIs so that any rate can be used. The new read/write VIs are attached and seem to work ok.
Best,
F

    How can read/write FORMSWEB.CFG & DEFAULT.ENV file entries programatically?

    I guess you cannot. There is an enhancement request to get the name of the config-section as a GET_APPLICATION_PROPERTY.
    What you could do is add extra parameter(s) to your form and pass the necessary formsweb.cfg parameters in this form parameter. See Get formsweb.cfg section name in Forms for more info and an example.

  • How to write new line to a File?

    How to write new line to a file?
    I have a string to be written to a file. the string contains "\n" in it. But why it is not showing the new line in the file.
    I have tryed FileWriter class and FileOutputStream class, but none of them works?
    any suggestion please...

    Probably using PrintStream::println() is a portable way.
    import java.io.FileOutputStream;
    import java.io.PrintStream;
    public class NewLine {
        public static void main(String[] args) {
         try {
             PrintStream ps = new PrintStream(new FileOutputStream("foo.txt"));
             ps.write("string".getBytes());
             ps.println();
             ps.close();
         } catch (java.io.IOException e) {
             e.printStackTrace();

  • How to write data to an XML file present under application server

    frnds: can ne one tell me, how to write data in to a file, which is present under a application server
    Ex: i want to write a string data in to a file test.txt which is present under "http://localhost:8080/<some_webapp>/test.txt"
    Note:i have deploted a service<some_webapp> under Tomcat/webapps dir

    Very simple. A servlet can writes to that file if it has the good rights.
    In the servlet get (or post) method, use a code like this:
    import java.io.*;
    protected void doGet(HttpServletRequest req, HttpServletResponse resp) {
    try {
    String filePath = this.getServletContext().getRealPath("/text.txt");//See http://java.sun.com/products/servlet/2.2/javadoc/javax/servlet/ServletContext.html#getRealPath(java.lang.String)
             PrintWriter writer = new PrintWriter (filePath);
            //or BufferedWriter out = new BufferedWriter(new FileWriter(filePath));
            writer .println("aString");
           writer.flush();
            writer .close();
        } catch (Exception e) {
           e.printStackTrace();
    }Hope That Helps

  • Send WAV sound file to Modem

    Hi,
    After I use JavaComm API to dial to a phone with a common
    dialup/Fax Modem, is it possible to output a WAV sound file
    to the modem so that the receiver(the one pickup the phone
    remotely) can hear the voice?
    Best regards,
    Eric

    Look at the javax.sound.sampled api.
    If your modem is capable of sending digital audio it should appear as
    one of the available mixers. find the correct mixer and stream your
    audio to it.

  • How do I convert a Simple Sound file to a .WAV file?

    Since I have a Mac Mini (w/Intel CPU) I don't have a built-in microphone.
    I do, however, have an OS 9.1 Wall Street Powerbook with a built-in mike.
    I'd like to send voicemail to friends who use Windows XP
    I used Simple Sound to record a message on the Powerbook and e-mailed
    it to myself. Now what? IMovieHD will apparently (according to Pogue) convert the sound portion of a movie to .WAV but when I open a New Project in IMovieHD my sound file is ghosted.
    Is there an app in Tiger that will convert the sound (voice) file? Or perhaps some freeware app out there?

    Hi, gwgoldb.
    USB microphones are very inexpensive. I'd suggest getting one of those and simply doing the recording on your new Mac Mini.
    For recording:
    • You could use the previously-suggested freeware Audacity to record and save the recording as .wav. Note Audacity isn't a Universal Binary at this time, so it would run under Rosetta.
    •  Use QuickTime Pro for recording and converting (export) the recording to .wav. Some people balk at paying US$ 29.99 for a QuickTime Pro key, but I find it does a nice job in basic recording, converting audio/video, and basic A/V editing, all with the simplicity of the QuickTime interface.
    Good luck!

  • Wav sound file equalizer-​indicator

    Hi all!
    I have a newbie question I'm stucked on a stage of designing a wav sound equalizer.
    The point of my equalizer is to indicate in the form of a equalizer the magnitude of diferent frequency ranges, while you listen to it. The playback sound of the wav file and it's indication of magnitude (equalizers) must be sinhronised. for example: if you hear a bang you must also see it on the indicators at the same time.
    I can't figure out how to setup a loop that would do that.
    Now i get only first set of magnitude.
    Thanks for the help.
    Solved!

    You have use chunks of the wav file in order to do what you want. Go to help in the toolbar. Select Find examples. Search for sound. Then locate the "\Sound File to Sound Output.vi" This will give you an idea on how to do things. Remember to save the example to your personal folder before you do any work on it.
    Besides which, my opinion is that Express VIs Carthage must be destroyed deleted

  • How continuously write data to a txt file

    hello, 
    first of all, sorry for bad English, but I have a problem to continuously write data to the txt file.... I have one 2D array with values of some function and based on 2 sliders (values of the sliders) i want to interpolate value using bilinear method... and after that value of the sliders, interpolated value, and value of the nearest points i wish to write to txt file ... for every 2-3 seconds perhaps it would be ideal to be formated as :: 
    x   y   f     f1   f2   f3   f4
    but... first i have problem with writing data, because every time it deletes old data and just write new one and it's not horizontal... I'm very very new at this (it is obvious) and any help will be very appreciative  
    thanks  
    Solved!

    Hi there,
    May I suggest you start with the LabVIEW tutorial?  Or perhaps this one?
    I say that because 1) you said you're new at this, and these tutorials are great for getting started; and 2) you don't seem to understand the concept of dataflow.
    A structure, such as a loop or subVI or function, cannot start executing until it has all of its inputs available.  Therefore, the loop which contains your file write (bottom loop) cannot execute until your top loop is done executing, because it depends on inputs from your top loop and those inputs aren't available until the top loop is finished.  Thus, your file will contain only the data from your final top loop execution.  You might be thinking that your loops are executing in parallel.  They are not.  Your file loop is executing after your data loop has finished...that is to say, your file loop executes exactly once, after you press your stop button.
    You can do two things here to fix that:
    1.  You can move your file write into the top (data) loop. (probably easier for now)
    2.  You can use a queue to transfer the data from your top (data) loop into your bottom (file write) loop. (more complex, but a better idea in the long run)
    One other thing.  Move the "open file" function outside the loop.  Opening and closing the file in each loop iteration will cause problems.  Open the file once.  Write to it in each loop iteration.  Close it when you're done.  Like this:
    Note that this is not complete code...you need to provide the data to write.  This is just to show you how to set up a continuous file write.
    Ok, start with the tutorials and we'll go from there. 

  • Read/Write folder, but newly added files Read Only?

    Our company uses a server to store a shared logo database and work files, and to transfer data from one user to another. At this point, we do not have any need for Read Only on this server; everything should be Read/Write. That's how it was set up initially, and the permissions were propagated. About a year ago, our old XServe crashed and was replaced with a new XServe. I believe our trouble started there, and has since migrated to our Snow Leopard Server: we have several folders where, if an employee uploads a folder and/or file, those files become Read Only. We have to go to the Get Info for that folder and fix the permissions each time. This has to happen up to 20 or so times a day, and I'm the only one who has server access to fix it; it also seems to be affecting more and more folders. I'm not in IT, so this is a little beyond me, but I've been working with IT on this (I'm Mac, he's PC). Can anyone offer a suggestion as to how else we can go about permanently setting the permission to Read/Write on all folders? Server Admin hasn't been successful.
    Thanks!

    Hi
    +"We have to go to the Get Info for that folder and fix the permissions each time"+
    This might be fine for OSX Client but it's not the way to do things on OSX Server. Consider stopping doing this because ultimately you're adding to the problems you're seeing. To reset permissions launch terminal on the server and issue this command:
    sudo chmod -R -N /pathtoshare
    Depending on how much data there is as well as the structure (nested folders within nested folders etc) this may take some time. If you're sharing the Volume (hard drive), don't. Share a folder instead. If you have only one share point which is the name of the drive. Create a folder with the same name and move all the data into that folder. Un-share the drive and Re-share the folder.
    Once the command has ran, repeat for any other share points you may have. When finished launch Server Admin because this is what you should be using. Select the Server name. Click on the Sharing icon. Select Share Points. Select the share point you're interested in and add desired users or groups into the ACL window. Select Read/Write. Don't fiddle with the POSIX permissions. Cick Save. Click on the small gear wheel and select Propagate Permissions. By default ACL will be ticked. You don't tick anything else. Click save/apply and let it do its stuff. Repeat for any other share points you may have.
