下载MpegAudioSPI1.9.4
http://www.javazoom.net/mp3spi/mp3spi.html
在项目中添加mp3spi1.9.4.jar jl1.0.jar tritonus_share.jar三个jar包
copy下面的代码到类中！
package org.mp3;
import java.io.File;
import javax.sound.sampled.AudioFormat;
import javax.sound.sampled.AudioInputStream;
import javax.sound.sampled.AudioSystem;
import javax.sound.sampled.DataLine;
import javax.sound.sampled.SourceDataLine;
public class TestMP3 {
boolean isStop = true;// 控制播放线程
boolean hasStop = true;// 播放线程状态
AudioInputStream audioInputStream;// 音频文件流
AudioFormat audioFormat;// 文件格式
SourceDataLine sourceDataLine;// 输出设备
// 播放
private void play() {
try {
isStop = true;// 停止播放线程
// 等待播放线程停止
while (!hasStop) {
System.out.print(".");
try {
Thread.sleep(10);
} catch (Exception e) {
}
}
System.out.println("");
File file = new File("/home/mayi/11.mp3");//linux路径
// 取得文件输入流
audioInputStream = AudioSystem.getAudioInputStream(file);
audioFormat = audioInputStream.getFormat();
// 转换mp3文件编码
if (audioFormat.getEncoding() != AudioFormat.Encoding.PCM_SIGNED) {
audioFormat = new AudioFormat(AudioFormat.Encoding.PCM_SIGNED,
audioFormat.getSampleRate(), 16, audioFormat
.getChannels(), audioFormat.getChannels() * 2,
audioFormat.getSampleRate(), false);
audioInputStream = AudioSystem.getAudioInputStream(audioFormat,
audioInputStream);
}
// 打开输出设备
DataLine.Info dataLineInfo = new DataLine.Info(
SourceDataLine.class, audioFormat,
AudioSystem.NOT_SPECIFIED);
sourceDataLine = (SourceDataLine) AudioSystem.getLine(dataLineInfo);
sourceDataLine.open(audioFormat);
sourceDataLine.start();
// 创建独立线程进行播放
isStop = false;
Thread playThread = new Thread(new PlayThread());
playThread.start();
} catch (Exception e) {
e.printStackTrace();
}
}
//线程！！
class PlayThread extends Thread {
byte tempBuffer[] = new byte[320];
public void run() {
try {
int cnt;
hasStop = false;
// 读取数据到缓存数据
while ((cnt = audioInputStream.read(tempBuffer, 0,
tempBuffer.length)) != -1) {
if (isStop)
break;
if (cnt > 0) {
// 写入缓存数据
sourceDataLine.write(tempBuffer, 0, cnt);
}
}
// Block等待临时数据被输出为空
sourceDataLine.drain();
sourceDataLine.close();
hasStop = true;
} catch (Exception e) {
e.printStackTrace();
System.exit(0);
}
}
}
public static void main(String args[]) {
TestMP3 test=new TestMP3();
test.play();
}
}
运行！ OK 有空研究研究 audiospl的源码！！
