java实现多个mav文件拼接合并成一个mav文件，绝对有效

java实现多个mav文件拼接合并成一个mav文件，绝对有效

解决方法:

import java.io.File;

import java.io.IOException;

import java.io.SequenceInputStream;

import java.util.ArrayList;

import java.util.List;

import javax.sound.sampled.AudioFileFormat;

import javax.sound.sampled.AudioInputStream;

import javax.sound.sampled.AudioSystem;

import javax.sound.sampled.UnsupportedAudioFileException;

public class AudioTest {

public static void main(String[] args) throws UnsupportedAudioFileException, IOException {

//生成的新.wav路径

File fileOut = new File("F:/jcwork/new.wav");

       List<String> listArr = new ArrayList<String>();

       listArr.add("F:/jcwork/one.wav");

       listArr.add("F:/jcwork/two.wav");

       listArr.add("F:/jcwork/three.wav");

//如果这个语音大于 2 个

if (listArr.size() >= 2){

  AudioInputStream audio1 = AudioSystem.getAudioInputStream(new File(listArr.get(0)));

  AudioInputStream audio2 = AudioSystem.getAudioInputStream(new File(listArr.get(1)));

  AudioInputStream audioBuild = new AudioInputStream(

        new SequenceInputStream(audio1, audio2),

        audio1.getFormat(),

        audio1.getFrameLength() +

              audio2.getFrameLength()

  );

  AudioInputStream audio3;

  //大于两个时继续合并

  for(int i = 2; i<listArr.size();i++){

     audio3 = AudioSystem.getAudioInputStream(new File(listArr.get(i)));

     audioBuild = new AudioInputStream(

           new SequenceInputStream(audioBuild, audio3),

           audioBuild.getFormat(), audioBuild.getFrameLength() +

           audio3.getFrameLength()

     );

  }

  //生成语音

  AudioSystem.write(audioBuild, AudioFileFormat.Type.WAVE, fileOut );

}

}

}
