Am I using CocosDenshion correctly?

Question

I found subtle leaks in my code. All of them arise when I play a sound or song.

This is what I call the sound effect:

[[SimpleAudioEngine sharedEngine] playEffect:@"myeffect.wav"]; 

This is how I play the song:

  [[SimpleAudioEngine sharedEngine] playBackgroundMusic:@"mysong.mp3"]; 

Somehow I had to free them after they finished or something else?

Answer 1

You are using it correctly. Are you sure you have a memory leak? SimpleAudioEngine will cache the audio file that you play for subsequent playbacks, so it is possible that you see an increase in memory, and then do not decrease.

Answer 2

To get the memory back, you need to call unloadEffect: on SimpleAudioEngine.
