java - 连接两个 WAV 文件失败

Question

我有这个简单的代码来连接两个 wav 文件。它非常简单，代码运行没有任何错误。但是输出文件有问题。生成的输出文件无法播放，令人惊讶的是它的大小只有 44 字节，而我的输入文件“a.wav”和“b.wav”的大小都超过 500Kb。

这是我的代码:

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 WavConcat {
    public static void main(String[] args) {
        String wFile1 = "./sounds/a.wav";
        String wFile2 = "./sounds/b.wav";

        try {
            AudioInputStream clip1 = AudioSystem.getAudioInputStream(new File(wFile1));
            AudioInputStream clip2 = AudioSystem.getAudioInputStream(new File(wFile2));

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

            AudioSystem.write(appendedFiles, 
                            AudioFileFormat.Type.WAVE,new File("./sounds/ab.wav"));
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
}

尝试这种结构。这对我有用

List audioInputStreamList = new ArrayList();

    String wFile1 = "./sounds/a.wav";
    String wFile2 = "./sounds/b.wav";

 AudioInputStream audioInputStream1 = AudioSystem.getAudioInputStream(new File(wFile1));
 AudioInputStream audioInputStream2 = AudioSystem.getAudioInputStream(new File(wFile2));

 audioInputStreamList.add(audioInputStream1);
 audioInputStreamList.add(audioInputStream2);

 AudioFormat audioFormat = audioInputStream1.getFormat(); // audioInputStream2 format also same

 AudioInputStream udioInputStream = new SequenceAudioInputStream(audioFormat,audioInputStreamList);

 AudioSystem.write(audioInputStream, AudioFileFormat.Type.WAVE,new File("./sounds/ab.wav"));

更新

检查 SequenceAudioInputStream
