title: iPhone game audio and background music
body: <p>Have a few questions related to adding sounds to my game, specifically intro music (for splash), background music (loop) and button event sounds. Hope you can share your knowledge on this.</p>
  
  <p>1) Should I use compressed sounds or uncompressed sounds? Or perhaps a combination of the two? Are there any limitations on the iPhone hardware that I should be aware of -- for example, the ability to play multiple compressed sounds?</p>
  
  <p>2) What's the best audio format for my purpose?</p>
  
  <p>3) For background music, I am thinking of using AVAudioPlayer.  For button event sounds, I am thinking of using AudioServicesPlaySystemSound, what do you think?</p>
  
  <p>4) Any other issues I should be aware of?</p>
  
  <p>Thank you!</p>
