Play Audio (mp3, ogg) from sd card with AudioTrack

Question

I want to play audio file from SD card with AudioTrack. I've tried with this code:

int minBufferSize = AudioTrack.getMinBufferSize(8000,
                AudioFormat.CHANNEL_CONFIGURATION_MONO,
                AudioFormat.ENCODING_PCM_16BIT);
        int bufferSize = 512;
        AudioTrack at = new AudioTrack(AudioManager.STREAM_MUSIC, 8000,
                AudioFormat.CHANNEL_CONFIGURATION_MONO,
                AudioFormat.ENCODING_PCM_16BIT, minBufferSize,
                AudioTrack.MODE_STREAM);

        int i = 0;
        byte[] s = new byte[bufferSize];

        FileInputStream fin = new FileInputStream(path);
        DataInputStream dis = new DataInputStream(fin);

        at.play();
        while ((i = dis.read(s, 0, bufferSize)) > -1)
        {
            at.write(s, 0, i);

        }
        at.stop();
        at.release();
        dis.close();
        fin.close();

But it doesn't play audio file properly. Instead of original audio it plays some kind noise sound.

From the following link i have found that AudioTrack only plays PCM audio, http://developer.android.com/guide/topics/media/index.html

And Please have a look on this code. http://mindtherobot.com/blog/624/android-audio-play-an-mp3-file-on-an-audiotrack/ this is provided the information about how to Play an MP3 file on an AudioTrack.

Hope this helps u .
