I have a wav file which was encoded with 16-bit PCM, I want to convert it to a PCM short array and play the raw array with audiotrack class. It is what I did:
String fileName = "test.wav";
File f = new File(baseDir + File.separator + fileName);
InputStream is = null;
try {
is = new FileInputStream (f);
} catch (FileNotFoundException e1) {
// TODO Auto-generated catch block
e1.printStackTrace();
}
BufferedInputStream bis = new BufferedInputStream (is, 8000);
DataInputStream dis = new DataInputStream (bis); // Create a DataInputStream to read the audio data from the saved file
short[] music = new short[(int) f.length()];
int i = 0; // Read the file into the "music" array
try {
while (dis.available() > 0)
{
music[i] = dis.readShort(); // This assignment does not reverse the order
i++;
}
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
Log.i("123",""+Arrays.toString(music));
try {
dis.close();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
at=new AudioTrack(AudioManager.STREAM_MUSIC, 8000, AudioFormat.CHANNEL_OUT_MONO,
AudioFormat.ENCODING_PCM_16BIT, 8000 /* 1 second buffer */,
AudioTrack.MODE_STREAM);
at.write(music, 0, (int)f.length());
at.play();
The array can be played, but the problem is that when I compare it with playing the original wav file, I found that they don't output the same sound. Can someone help me with this issue? Thank you in advance!
