Play a .wav file fractional
hi,
i´m looking for a solution to play a .wav file.
the special what i need is, that i want to jump to concrete points on the timeline.
or can i seperate the timeline of a .wav file?

Hi Martin
this could help you starting. For the case you can't open LV 8.2- VIs, i attach the BD- picture.
greets, Dave

Playing a wav file (byte array) using JMF
Hi,
I want to play a wav file in form of a byte array using JMF. I have 2 classes, MyDataSource and MyPullBufferStream. MyDataSource class is inherited from PullStreamDataSource, and MyPullBufferStream is derived from PullBufferStream. When I run the following piece of code, I got an error saying "EXCEPTION_ACCESS_VIOLATION (0xc0000005) at pc=0x7c9108b2, pid=3800, tid=1111". Any idea what might be the problem? Thanks.

Playing a .wav file from email attachment

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 CorporationHi 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.

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. -

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

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
Hello all,
I need to play a wav file to LINE_OUT port, but not to the SPEAKER. I am trying to do this under window NT. For some reason I get false for isLineSupported(Port.Info.LINE_OUT). I am new to javax.sound so I might be doing something wrong. Here is the code that I am using to iterate through all availible mixers and check if LINE_OUT is supported by any of them:
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)) {
System.out.println("the port is supported");
try {
Port line = (Port) AudioSystem.getLine(
Port.Info.LINE_OUT);
catch(Exception ex){
ex.printStackTrace();
else{
System.out.println("the port is not supported");
Please helpThe new bugID of the request to implement Ports is: 4558938.

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 - BruceHello,
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 do you open/play a .wav file (music file) without play sound file .vi
I am having big problems to create a music background for my project. I am newbie using labview and maybe my questions is not so dificult to solve (I hope so)
I was using play sound file vi but the problem is that I dont want the music file start automatically. I wanna control the start time using a button. I tried include a sound output stop but when the app start and I add more wav files in my vi, the sound file start, then stop abruptally because the stop vi and the everything is normal. I would like to eliminate that error.
Someone have any idea, maybe using open file or another way.
Thanks in advance
I add a screenshot of my vi and also the vi in this post

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.

Reading, filtering and playing large WAV files
Hi!
I want to build an application that reads LARGE wavefiles, filters them and plays them via the soundcard.
I tried to build something with the standard blocks available in Labview 7.0, but I keep running out of memory. The files I want to filter and play are simply too large The filesize is typ. 650Mb = 1 hour of stereo CD quality audio. The files I am using just won't play even on a WIN XP machine with 1Gb of memory.
Next step was to build a function that loads the WAV files in blocks of ~16kB. This works fine, but now the filtering does not work anymore; after each block, the 'FIR Filter' block seems to reset its states. The result is a very bad repeating artifact in the sound. The repetition-rate is related to the buffer size.
Does anyone have experience with this type of application? Help and examples are -very- welcome (as I am new to Labview... .
Many thanks,
Dr.dBI have created a VI that will do the continuous FIR filtering you need. I assume you want to filter a 'stereo' signal so the VI takes an array of waveforms as input. In this version the FIR filter coefficients (kernel) is common to all channels. If this is not what you need you can correct the VI accordingly.
The control 'algorithm' specifies whether the FIR convolution is internally performed in the time or frequency domain. Changing the 'algorithm' does not affect your result but affects your performances. Select time domain (direct) if your kernel size (number of FIR coefficients) is, say less than 100, otherwise select 'frequency domain'.
Try the attached example and let me know if you have any problems.
