My app audio sounds different when running the app?

Hi,

I have:

Code :

---

final MediaPlayer mp = MediaPlayer.create(this, R.raw.popping_sound_effect);

---

When I play the sound file it is how I want it to be, but when I run the app and making the MediaPlayer play the sound is different, it is the correct sound but it is much deeper for some reason?

Thanks.

I found out why....

The format of the sound file was .wav, i changed it to a .mp3 and now it sounds as it should.
