Getting audio to play in the background of my GUI.

[GregK]

Hi

I'd like to be able to play audio in the background of my GUI using a JFRAME, is this possible?

I just want to load one audio file and have another play upon certain actions. I don't want audio to be selectable or anything I just want it to play as the GUI runs.

If anyone could start me off onwhere to look or give me a code snippet to get me going I'd really appreciate it. I've looked around abit and can't really find much.

This article from OnJava might help you out a bit. And BTW, I found it as well as many others with a simple google search using Java Swing play wav file.

I'm still having loads of trouble with this.

I'm trying to embed ONE audiofile into my gui to load on startup as the gui is initialised. I've tried an AudioClip interface method using the getDocumentBase() method when loading the sounds but I get an error saying 'cannot find symbol - getDocumentBase'

I've tried another way using the following code -

public void audioFile()
    {
    try {
        // From file
        AudioInputStream stream = AudioSystem.getAudioInputStream(new File("test.wav"));
    
        // From URL
        //stream = AudioSystem.getAudioInputStream(new URL("http://hostname/audiofile"));
    
        // At present, ALAW and ULAW encodings must be converted
        // to PCM_SIGNED before it can be played
        AudioFormat format = stream.getFormat();
        if (format.getEncoding() != AudioFormat.Encoding.PCM_SIGNED) {
            format = new AudioFormat(
                    AudioFormat.Encoding.PCM_SIGNED,
                    format.getSampleRate(),
                    format.getSampleSizeInBits()*2,
                    format.getChannels(),
                    format.getFrameSize()*2,
                    format.getFrameRate(),
                    true);        // big endian
            stream = AudioSystem.getAudioInputStream(format, stream);
        }
    
        // Create the clip
        DataLine.Info info = new DataLine.Info(
            Clip.class, stream.getFormat(), ((int)stream.getFrameLength()*format.getFrameSize()));
        Clip clip = (Clip) AudioSystem.getLine(info);
    
        // This method does not return until the audio file is completely loaded
        clip.open(stream);
    
        // Start playing
        clip.start();
    } catch (MalformedURLException e) {
    } catch (IOException e) {
    } catch (LineUnavailableException e) {
    } catch (UnsupportedAudioFileException e) {
    }
}    

Inside my gui, don't get any errors but nothing happens when i call the method.

Can someone help me?
