To play a wav file read the wav file and pass the bytes to audio track chunck by chunk. private void playWaveFile(){                 // define the buffer size for audio track         int minBufferSize = AudioTrack.getMinBufferSize(8000, AudioFormat.CHANNEL_OUT_MONO, AudioFormat.ENCODING_PCM_16BIT);         int bufferSize = 512;         AudioTrack audioTrack = new AudioTrack(AudioManager.STREAM_VOICE_CALL, 8000, AudioFormat.CHANNEL_OUT_MONO, AudioFormat.ENCODING_PCM_16BIT, minBufferSize, AudioTrack.MODE_STREAM);         String filepath = "File Path";         int count = 0;         byte[] data = new byte[bufferSize];         try {             FileInputStream fileInputStream = new FileInputStream(filepath);             DataInputStream dataInputStream = new DataInputStream(fileInputStream);             audioTrack.play();                         while((count = dataInputStream.read(data, 0, bufferSize)) > -1){                 audioTrack.write(data, 0, count);
