问题描述
我有麻烦选择合适的音频播放技术。有一吨的技术，在iPhone上使用，它是如此的混乱。
I have trouble choosing the right audio playback technology. There's a ton of technologies to use on the iPhone, it's so confusing.
我需要做的是这样的：
-
开始打短的声音范围0.1至2秒。
start playing short sounds ranging between 0.1 and 2 seconds
高品质的回放，无裂纹（我听到一些iPhone的音频播放技术做起点和终点的噼啪声，这是坏的！）
high quality playback, no crackle (I heard some of the iPhone audio playback technologies do a crackle sound on start or end, which is bad!)
的能力，开始声音的播放，同时还有已经另外一个现在打右（二，在同一时间三个或三个以上的声音）
ability to start playback of a sound, while there's already another one playing right now (two, three or more sounds at the same time)
什么你会建议在这里，为什么？感谢： - ）
What would you suggest here, and why? Thanks :-)
推荐答案
有基本上在iPhone上播放音频四个选项：
There are basically four options for playing audio on the iPhone:
-
Audio工具箱。容易的，但不仅有利于在应用程序中播放声音效果（）。
Audio Toolbox. Easy, but only good for playing sound effects in applications (sample code).
Audio队列服务。功能非常强大，可以做任何事情。 C API，pretty凌乱的工作。回调，水桶，疼痛。
Audio Queue Services. Very powerful, can do anything. C API, pretty messy to work with. Callbacks, buckets, pain.
AVAudioPlayer.关于最简单的选择。可以播放COM pressed音频，用一个简单的包装，你可以轻松播放同一样品的多个实例一次（仅限于非COM pressed声音，因为只有一个硬件音频解codeR）。开始播放声音与 AVAudioPlayer 似乎的，可以是一个问题。
AVAudioPlayer. About the easiest option. Can play compressed audio, with a simple wrapper you can easily play multiple instances of the same sample at once (non-compressed audio only, as there is only one HW audio decoder). Starting to play a sound with AVAudioPlayer seems to lag about 20 ms, could be a problem.
。复杂性和功能之间的妥协得体。声音不落后，可以打多个声音就好了，但你必须做大量的工作自己。我已经写了名为声音引擎，可以帮助你。
OpenAL. Decent compromise between complexity and features. Sounds do not lag, you can play multiple sounds just fine, but you have to do a lot of the work yourself. I’ve written a sound engine called Finch that can help you.
不知道很多有关开裂，从来没有经历过。我想有一些问题，打无缝融为一体pressed循环与 AVAudioPlayer ，可以保存循环，不COM pression被克服。
Don’t know much about cracking, never experienced it. I think there were some issues with playing seamless compressed loops with AVAudioPlayer, can be overcome by saving the loop without compression.
