如何在java中合并两个mp3文件？

Question

i have tow audio files and i want to join that two audio files using java codding or any java Audio-Sound API.

 String wavFile1 = "D://SampleAudio_0.4mb.mp3";
     String wavFile2 = "D://wSampleAudio_0.7mb.mp3";
     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://merge1.mp3"));

I get the following exception:

javax.sound.sampled.UnsupportedAudioFileException: could not get audio input stream from input file at javax.sound.sampled.AudioSystem.getAudioInputStream(Unknown Source)

Answer 1

Got the Solution and It's Working for me.

String wavFile1 = "C:\\1.mp3";
String wavFile2 = "C:\\2.mp3";
FileInputStream fistream1 = new FileInputStream(wavFile1);  // first source file
FileInputStream fistream2 = new FileInputStream(wavFile2);//second source file
SequenceInputStream sistream = new SequenceInputStream(fistream1, fistream2);
FileOutputStream fostream = new FileOutputStream("D://merge1.mp3");//destinationfile

int temp;

while( ( temp = sistream.read() ) != -1)
{
    // System.out.print( (char) temp ); // to print at DOS prompt
    fostream.write(temp);   // to write to file
}
fostream.close();
sistream.close();
fistream1.close();
fistream2.close();

I think .7mb.mp3 is recognised as a .7mb extension. Make sure that's not causing problems. Try to rename your files this way:

From:

String wavFile1 = "D://SampleAudio_0.4mb.mp3";
String wavFile2 = "D://wSampleAudio_0.7mb.mp3";

To:

String wavFile1 = "D://SampleAudio_01.mp3";
String wavFile2 = "D://wSampleAudio_02.mp3";

Update

I didn't see that you have answered the question already, but I think it's worth keeping on eye on the extensions in the future.
