Android將兩個音頻文件合併爲一個

Question

我有兩個.3gp（或.wav）音頻文件，我已經從用戶的麥克風中保存。我怎樣才能將這兩個音頻文件在代碼中連接成一個文件？謝謝。

Answer 1

組合兩個wav文件：

import java.io.File; 
import java.io.IOException; 
import java.io.SequenceInputStream; 
import javax.sound.sampled.AudioFileFormat; 
import javax.sound.sampled.AudioInputStream; 
import javax.sound.sampled.AudioSystem; 

public class WavAppender { 
    public static void main(String[] args) { 
     String wavFile1 = "D:\\wav1.wav"; 
     String wavFile2 = "D:\\wav2.wav"; 

     try { 
      AudioInputStream clip1 = AudioSystem.getAudioInputStream(new File(wavFile1)); 
      AudioInputStream clip2 = AudioSystem.getAudioInputStream(new File(wavFile2)); 

      AudioInputStream appendedFiles = 
          new AudioInputStream(
           new SequenceInputStream(clip1, clip2),  
           clip1.getFormat(), 
           clip1.getFrameLength() + clip2.getFrameLength()); 

      AudioSystem.write(appendedFiles, 
          AudioFileFormat.Type.WAVE, 
          new File("D:\\wavAppended.wav")); 
     } catch (Exception e) { 
      e.printStackTrace(); 
     } 
    } 
}
