Playing a .wav file loaded from filesystem

I am trying to play a local file and getting:
Have not been able to load: MediaError: media unsupported:com.sun.media.jmc.MediaUnsupportedException: Unsupported media: file:///product-name/lib/buzzer.wav
I get a different exception if the file does not exist, so the message seems to be saying it has a problem with .wav files, or this .wav file in particular??
I am using 1.3, but this page is for 1.2:
http://download.oracle.com/javafx/1.2/tutorials/media/format.html
There doesn't seem to be an equivalent page for 1.3. If 1.2 rules still applied then for Audio on Vista the resolution under 'Supported Media Codecs' is "All the audio formats supported by Windows Media Player". And [this file|http://www.strandz.org/javafxstreaming/buzzer.wav] certainly works on Windows Media Player.
package def alarmSoundPlayer = MediaPlayer
    media: makeFilesystemMedia( "file:///product-name/lib/buzzer.wav");
    autoPlay: false;
    repeatCount: 1;
public function makeFilesystemMedia( fileName: String): Media
    var music = Media
        source: fileName
        onError: function( mediaError: MediaError)
            println( "Have not been able to load: {mediaError}");
    return music;
}

It might not be the issue, but the file:///product-name/lib/buzzer.wav is strange. Aren't you missing a drive specification? (might not be necessary if on the same disk, but still unusual). Is the "product-name" at the root of the disk? When in doubt of URL syntax, you can still use a path to initialize a File object, then get toURI().toURL() to have a normalized URL.
HTH.

Subsequent play of WAV files from HTTP

Hi,
I have to subsequently play many WAV files from HTTP in a nokia series 60 emulator.
Everything is ok for the first two files, but at the third I catch an exception:
"java.io.IOException: exceeded the configured maximum number of connections"
I tried two ways to load the files from HTTP:
Manager.CreatePlayer(InputStream...)
Manager.CreatePlayer("http:\\...")
Below there is the code of the two methods I use. Please note that I try in every way to close the connection before open a new one!!!
public void Method_1(String src, String type){
int iLen=0;
is = null;
httpCon = null;
byte[] bBuf;
try {
if (p != null) {
if (p.getState() == Player.STARTED) {
p.stop();
p.removePlayerListener(this);
p.deallocate();
p.close();
p=null;
if (is!=null){
is.close();
is=null;
if (httpCon!=null){
httpCon.close();
httpCon=null;
httpCon = (HttpConnection) Connector.open(src);
if (httpCon.getResponseCode() != HttpConnection.HTTP_OK) {
System.out.println("Bad response code");
return;
System.out.println("Connection OK! (audio)");
iLen = (int) httpCon.getLength();
System.out.println("audio file length : " + iLen);
is = httpCon.openInputStream();
p = Manager.createPlayer(is, type);
p.addPlayerListener(this);
p.setLoopCount(1);
p.prefetch();
p.start();
vc = (VolumeControl)p.getControl("VolumeControl");
catch (MediaException ex) {
ex.printStackTrace();
catch (IOException ex) {
ex.printStackTrace();
public void Method_2(String src){
try {
if (p!=null){
if (p.getState() == Player.STARTED)
p.stop();
p.deallocate();
p.close();
p=null;
p = Manager.createPlayer(src);
p.addPlayerListener(this);
p.setLoopCount(1);
p.start();
vc = (VolumeControl)p.getControl("VolumeControl");
catch (java.io.IOException e) {
e.printStackTrace();
catch (MediaException e) {
e.printStackTrace();

My question is:
how can I load (from a HTTP server) and play more than two WAV files without crashing?
Do I have to close the connection in a better way in order to re-open it without problems (and more than two times)?
It is simply an emulator bug?
Thanks.

Playing a .wav file from email attachment

Playing a wav file (byte array) using JMF

Need Help playing a wav file on PDA

Does anyone have a SIMPLE example of playing a wav file on a PDA using LabView PDA. The only working example I can find from NI "Advance Sound Example for LabVIEW PDA for Pocket PC" is a jumbled of confusing functionality. I'm mainly looking for a simple "play" example, but a simple "record" example would be helpful also.
Thanks - Bruce

Hello,
Well, I looked through the example code I tried to break it down to the point where you could create a simple Play VI. Unfortunately, I don't have the PDA target, so I'm uncertain if the little example that I have attached will run or not. If not, I also took a screen shot so you can see what VIs I used. I'm pretty sure I only used VI's that I found on the example itself.
Good luck.

How to play a wave file through the DAQ board?

Hi there,
we want to play a wave file that is saved on the harddrive via the DAQ board. Means we want to connect a amp to the analog output of the DAQ to amplify the sound and play it through a speaker.
We couldn't find any VI that does that. Can anybody tell us how to play a wave file, or perhaps even send us a VI that can do that?
Thanks a lot for your help
Martin - Physical Optics Corporation

Hi Martin,
The only example that I could find on how to do this was using our
older Traditional DAQ drivers version 6.9.3. If you're using Traditional
DAQ drivers, the vi can be found here.
The example reads a 8-bit mono .wav file (an example .wav file is included in the .zip file) and writes it to the analog out of your DAQ card. I've updated the
example to work with our newer DAQmx drivers and attached it here.
I hope this helps,
Paul C.

I just want to know what Apple computer to get to play Civilization V down loaded from the App store.

I just want to know what Apple computer to get to play Civilization V down loaded from the App store.
The game Civ5 processes a turn in single core mode. It says “please wait” while it processes a turn. If the intel i7 CPU is “fourth generation” it is twice as fast for civ5 turn processing. It does not matter if you have more memory or a better graphics chip. So, I can get a smaller cheeper Apple computer as long as it is fourth generation. I tested three new iMacs, two new MacPros and two mac minis.
See:
http://apolyton.net/showthread.php/193302-Civ-5-Processor-performance-analyzis-a t-Gamespot
I have looked at that darned “please wait” message for years. Now it can be 60 seconds on a new MacPro6,1 or late 2012 Mac mini and 30 seconds on a new iMac. Even the 21.5 iMac 3.1 GHz has 3.9 GHz turbo boost for single core and it is supposed to be fourth generation.
Some of that does not seem to true for the new 21.5 inch iMac I just tested (Fusion drive). Mac Mini 54 seconds 21.5 iMac 49 seconds.

Legality aside (I'm not a lawyer and have no opinion on the matter) in order to make a purchase of an iPhone 5 you would need to travel to a country where they are for sale and purchase it there. Be sure to get one that is officially unlocked or you would not be able to use it with your cell carrier. Be sure that your carrier supports use of the iPhone before you buy. Also note that the warranty of the iPhone is only valid in the country of purchase.

Play a wav file once

how do I play a wav file just once using the play sound
file.vi. i keep getting it to repeat over and over
thanks

First may I recommend some reading here. This is not meant to be cocky just to help you.
Getting Started with NI LabVIEW Student Training
LabVIEW101
Second I have included sort of template. Notice the wire that ends in the while loop. This will ensure that the wav is played before the loop starts.
Good luck with your Labview labwork
Besides which, my opinion is that Express VIs Carthage must be destroyed deleted
(Sorry no Labview "brag list" so far)

How do I play the .wav file google mail sends me on my Iphone 5?

I have cable phone service that sends out a .wav file of any voicemails I recieve to my e-mail account. I use google mail on my Iphone, and cannot play the .wav file that is attached to that e-mail. When I click on the "audio message box", it brings up a circle containing a south-west facing arrow which has a slash through it.

I have the latest software (6.1.4) and I can play the attachment if I go through "Mail" instead of "GMail". I am still not certain why I have a widget called "Mail".
Inside the "Mail" app, there are it's own Inbox, VIP, Flagged, etc which are all in color. Further down the list is my GMail boxes and sub-boxes. They are all grayed out, but still funtional.
Do I have something set up wrong causing me to be unable to play the .wav files that come to me through gmail?

How to play a wav file to LINE_OUT with javax.sound.sampled

Mixer.Info[] mixers = AudioSystem.getMixerInfo();
for(int i = 0; i < mixers.length; i++){
Mixer mixer = AudioSystem.getMixer(mixers);
if (mixer.isLineSupported(Port.Info.LINE_OUT)) {

try {
Port line = (Port) AudioSystem.getLine(
Port.Info.LINE_OUT);

Play music files loaded from pc

Hi all, is it possible to play music files copied over from a pc ? I have transferred music files over from pc which was ok but cannot work out how to play them! I am unable to find anything on my iphone to play them. They were copied from Real player. Can anyone help with this please?
Sam xx

By design, the iphone will sync itunes content with ONE computer at a time. ANY attempt to sync such content with a second computer will result in ALL itunes content being first deleted from your phone & then replaced with the content from the second computer. This is a design feature and cannot be overridden.
You need to decide what computer you want to sync itunes content with & stick with that computer.
