How to read mp3 file to a byte array in Java?

Question

I want to read the content of the .mp3 file into a byte array(Not including header and metadata). For this purpose I'm using following code.

File myFile = new File("C:\\Users\\Kaushal28\\Desktop\\a.mp3");
    byte[] samples;

    AudioInputStream is = AudioSystem.getAudioInputStream(myFile);
    DataInputStream dis = new DataInputStream(is);      //So we can use readFully()
    try{
        AudioFormat format = is.getFormat();
        samples = new byte[(int)(is.getFrameLength() * format.getFrameSize())];
        dis.readFully(samples);
    }
    finally{
        dis.close();
    }

Here is the link where it is posted: Here.

I executed this code with a mp3 file of a song. but got following exception:

javax.sound.sampled.UnsupportedAudioFileException: could not get audio input stream from input file

I've also tried this with .au file type, but got same exception.

For this I searched on Internet and found this: This SO link.

It says that all wav formats are not supported by java. Is it also true for .mp3 file formats? Or any other reasons due to which I'm getting this exception?

You need to use a separate library for mp3, see for example http://stackoverflow.com/a/24337995/2670892 — greg-449, Apr 02 '17 at 07:13
I don't want to play. I want to store it in array for further manipulations. — Kaushal28, Apr 02 '17 at 07:20
The Javazoom library that answer links to provides the code to do that. — greg-449, Apr 02 '17 at 07:22
