这里须要用到一个jar包:jave-1.0.1.jar,下载地址的话自己百度吧.

废话不多说直接贴代码：

import it.sauronsoftware.jave.AudioAttributes;
import it.sauronsoftware.jave.Encoder;
import it.sauronsoftware.jave.EncodingAttributes;

import java.io.File;




public class Test {
    
    /**
     * 运行转化过程
     * 
     * @param source
     *            源文件
     * @param desFileName
     *            目标文件名称
     * @return 转化后的文件
     */
    public static File execute(File source, String desFileName)
            throws Exception {
        File target = new File(desFileName);
        AudioAttributes audio = new AudioAttributes();
        audio.setCodec("libmp3lame");
        audio.setBitRate(new Integer(36000)); //音频比率 MP3默认是1280000
        audio.setChannels(new Integer(2));
        audio.setSamplingRate(new Integer(44100));
        EncodingAttributes attrs = new EncodingAttributes();
        attrs.setFormat("mp3");
        attrs.setAudioAttributes(audio);
        Encoder encoder = new Encoder();
        encoder.encode(source, target, attrs);
        return target;
    }
    
   public static void main(String[] args) throws Exception {
           File file = new File("c://1111.wav");
           execute(file,  "c://111.mp3");
   }
}
