   I'm looking for a method similar to [[CCDirector sharedDirector] purgeCachedData] for the SimpleAudioEngine.

   I preload sound effects for my game, but various levels require different sound effects, I noticed that I'm perhaps wasting memory by leaving effects from the first level loaded when they aren't needed.

   I know I could use...

   [[SimpleAudioEngine sharedEngine] unloadEffect:@"effect.wav"]

   ...but sometimes I want to unload 10-20 effects. I've been poking around and can't find a method that unloads them all. (I realise this could be wasteful if I am reloading some sounds I've just unloaded, so I would need to be careful, but there are certain circumstances where it's required.)

   I'm thinking I'll just create an array of strings, adding a string every time I load an effect, and then looping through it and removing them once I don't need them anymore.

   yeah, I just manually preload and unload effects, its not the most elegant thing in the world, easy to miss one.

   You could also subclass SimpleAudioEngine or just edit it and implement a method like "unloadAllEffects".

   You should be able to do it with a category on CDBufferManager and a category on SimpleAudioEngine. A CDBufferManager instance is used by SimpleAudioEngine to keep track of the mapping between a file name and the sound id.

   okay, thanks steve, i'd noticed the buffermanager when playing around after posting. If I come up with anything particularly special ill repost for others to use.
