O arquivo abaixo, toca um arquivo wav qualquer. Isso ocorre ao clicar no botao play. O q to tentando fazer é tocar o arquivo, ao inicializar o Frame, ou ate mesmo sem precisar da janela!!! Tem como?

Tinha esquecido, precisa desses arquivos para rodar…

SoundLoader.java

[code]
import java.applet.;
import javax.swing.;
import java.net.URL;
import java.net.MalformedURLException;

class SoundLoader {
SoundList soundList;
URL completeURL;
String relativeURL;

public SoundLoader(SoundList soundList,
                   URL baseURL, String relativeURL) {
    this.soundList = soundList;
    try {
        completeURL = new URL(baseURL, relativeURL);
    } catch (MalformedURLException e){
        System.err.println(e.getMessage());
    }
    this.relativeURL = relativeURL;
    AudioClip audioClip = Applet.newAudioClip(completeURL);
    soundList.putClip(audioClip, relativeURL);        
}

}[/code]

SoundList.java

[code]

import java.applet.AudioClip;
import javax.swing.*;
import java.net.URL;

/**

  • Loads and holds a bunch of audio files whose locations are specified

  • relative to a fixed base URL.
    */
    class SoundList extends java.util.Hashtable {
    JApplet applet;

    public SoundList(URL baseURL) {
    super(1);
    this.baseURL = baseURL;
    }

    public void startLoading(String relativeURL) {
    new SoundLoader(this, baseURL, relativeURL);
    }

    public AudioClip getClip(String relativeURL) {
    return (AudioClip)get(relativeURL);
    }

    public void putClip(AudioClip clip, String relativeURL) {
    put(relativeURL, clip);
    }

Depois de muito procurar… achei a resposta procurando no google!!! ai vai…

import java.io.*;
import javax.sound.sampled.*;
public class soundPLAY {
	
	private AudioFormat format;
	private byte[] samples;
	
	public soundPLAY(String filename){
		try{
			AudioInputStream stream = AudioSystem.getAudioInputStream(new File(filename));
			format = stream.getFormat();
			samples = getSamples(stream);
		}
		catch (UnsupportedAudioFileException e){
			e.printStackTrace();
	}
	catch (IOException e){
			e.printStackTrace();
		}
	}
	
	public byte[] getSamples(){
		return samples;
	}
	
	public byte[] getSamples(AudioInputStream stream){
		int length = (int)(stream.getFrameLength() * format.getFrameSize());
		byte[] samples = new byte[length];
		DataInputStream in = new DataInputStream(stream);
		try{
			in.readFully(samples);
		}
		catch (IOException e){
			e.printStackTrace();
		}
		return samples;
	}
	
	public void play(InputStream source){
		// 100 ms buffer for real time change to the sound stream
		int bufferSize = format.getFrameSize() * Math.round(format.getSampleRate() / 10);
		byte[] buffer = new byte[bufferSize];
		SourceDataLine line;
		try{
			DataLine.Info info = new DataLine.Info(SourceDataLine.class, format);
			line = (SourceDataLine)AudioSystem.getLine(info);
			line.open(format, bufferSize);
		}
		catch (LineUnavailableException e){
			e.printStackTrace();
			return;
		}
		line.start();
		try{
			int numBytesRead = 0;
			while (numBytesRead != -1){
				numBytesRead = source.read(buffer, 0, buffer.length);
				if (numBytesRead != -1)
					line.write(buffer, 0, numBytesRead);
			}
		}
		catch (IOException e){
			e.printStackTrace();
		}
		line.drain();
		line.close();
	}
	
	public static void main(String[] args){
		soundPLAY player = new soundPLAY("arq.wav");
		InputStream stream = new ByteArrayInputStream(player.getSamples());
		player.play(stream);
		System.exit(0);
	}
	
}

Toca o arquivo wav… sem construir a janela da aplicação…
