java实现wavToMP3格式转换详解编程语言

这里需要用到一个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 {   
           
        /**  
         * 执行转化过程  
         *   
         * @param source  
         *            源文件  
         * @param desFileName  
         *            目标文件名  
         * @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");   
       }   
    }
