A fast, easy to use, free, and community supported 2D game engine

I have my app working perfectly, however it's huge due to the background music that I left as a wav file. I converted it to ogg and got it to run using the Cocos2D sound engine. However, the ogg file loads really slowly even though it is 10 MB smaller than the wav file that loaded fast.
I tried using the ogg and the code from the Cocos2D project. Still loading slowly. Any suggestions?
Thanks!

Don't use Ogg. What you are doing now is converting Ogg Vorbis to little endian PCM for playback, as you pointed out that is slow. If you use mp3 it will be decoded by hardware on the fly so loading times are minimal. If you use AVAudioPlayer to play the mp3 files it is easy, the only downside with this approach is that you are only compatible with OS 2.2 onwards.

Ok, thanks for the tip. I got AVAudioPlayer to work fine. The reason I liked using PASoundMgr is that it took care of preloading/caching the file. Now, when I load the game up, there are hiccups because it is still loading/streaming the mp3 file. I've never done preloading outside of cocos2d texture loader/sound manager. Are there any good tutorials on it available?
Thanks!

You should probably look at SimpleAudioEngine from CocosDenshion before you implement something yourself. It may be adequate for your needs. If you want to do something yourself then have a look at Apple's documentation on NSOperation and NSOperationQueue - it is a pretty straightforward way to implement multi-threading.
Are you using OS 3.0? If so I'm concerned your mp3 is being decoded by software rather than hardware. How are you setting up your audio session?
