iPhone SDK：使用coreAudio播放声音

Question

So far i've been using AudioServices to play sounds in my drum app which caused horrible lag etc. I've been told that if i use coreAudio there will be no lag abd the performance will be better.The person also told me that AudioServices is only used to play short alert sound.

Any idea where i could start with CoreAudio?

If you have any code, it's helpful too :) but tutorials would be better :D.

Thanks in advance!

I really recommend Apple's documentation and the sample apps they provide:

• Core Audio Overview
• Audio Unit Hosting Guide for iOS

Example Apps

• Audio Mixer (MixerHost)
• oalTouch
• SpeakHere
• iPhoneMultichannelMixerTest
• iPhoneMixerEQGraphTest
• MusicCube
