示例：压缩MP3文件

package test;import java.io.File;import it.sauronsoftware.jave.AudioAttributes;import it.sauronsoftware.jave.Encoder;import it.sauronsoftware.jave.EncoderException;import it.sauronsoftware.jave.EncodingAttributes;import it.sauronsoftware.jave.InputFormatException;public class TestCompressMp3 {    public static void main(String[] args) throws Exception {        // TODO Auto-generated method stub        testCompressMp3Samll();    }    public static void testCompressMp3Samll() throws Exception{        Long t1 = System.currentTimeMillis();        AudioAttributes audio = new AudioAttributes();        audio.setCodec("libmp3lame");        audio.setBitRate(64000);//设置比特率        audio.setSamplingRate(44100);        EncodingAttributes attrs = new EncodingAttributes();        attrs.setFormat("mp3");//设置格式        attrs.setAudioAttributes(audio);//      attrs.setDuration(360f); // 设置截取的时长        Encoder encoder = new Encoder();        encoder.encode(new File("D:/test/1.mp3"),                 new File("D:/test/target64.mp3"), attrs);        Long t2= System.currentTimeMillis();        System.out.println("消耗："+(t2-t1)+"ms");    }}
