I am making a simple application for iPhone, and I want to enter a short audio file on an object click. Which of .caf and .wav would be better?
我是在Cocos2d的简单应用。 两种声音的记忆问题是什么?
If you do not need specific Core Audio Format features, then WAV has more universal support (and it would be my default choice for that reason).
核心音频格式基本上作为其他音频文件格式(包括WAV)的集装箱运作。 核心音频格式有许多特点,但从你需要的任何描述中看不出。
In response to a deleted comment, which was moved to the question:
我可以具体讲科科的话,因此,我将撰写整个档案格式: 该系统不使用数据压缩。 CAF可以。 如果是简短的档案,你很可能不提want数据压缩(因为需要大量的处理才能转换到LPCM。 如果你经常玩笑,那么你就希望把录音数据保存到一个令人不快的版本,以方便处理。 第二种要求是:44100* 2 bytes at CDquality in Memory (per sources).
短音档案,如气球,有16个甚小的西维射线。 从这个意义上来说,记忆差异不应成为决定因素。 如果你拥有大量音频文件,或长期音频文件,以备记忆,局势就会发生变化。 现在,我不认为记忆是你的问题。 由于CAF是一个集装箱,其未压缩的代表性将几乎相同(CAF的差别数据将略微增加)。
CAF文件基本上是Coreudio Format。 因此,它非常适合 Apple果框架。 在你能够拥有超过4个GB的档案时,以及在CAF中,CAF相对于WAV的最好优势是,在每张包装记录之后,你不需要更新WAV的头盔。
无论如何,我假定,你不需要这些与非洲武装部队有关的特征。 正如Justin所说,我确实认为: 西维协会将是一个更好的选择:,因为你比北美自由贸易协定格式能够获得更多支持。
