Part of this app is a "Scream" button that plays random screams from cast members of a TV show. I have to bang on the app quite a while to see a memory leak in Instruments, but it's there, occasionally coming up (every 45 seconds to 2 minutes.) The leak is 3.50kb when it occurs.

But then I alloc another UIViewController B and add its view as a subvie...
I want to read a sound file from application bundle, copy it, play with its maximum volume level(Gain value or peak power, I'm not sure about the technical name of it), and then write it as another file to the bundle again.
