Join two WAV files from Java?

Here is the barebones code:

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();
        }
    }
}

I found this (AudioConcat) via the "Code Samples & Apps" link on here.

The WAV header should be not be too hard to parse, and if I read this header description correctly, you can just strip the first 44 bytes from the second WAV and simply append the bytes to the first one. After that, you should of course change some of the header fields of the first WAV so that they contain the correct new length.
