勾选要保存在内存中的声音。 AVA音频播放器？系统声音？核心音频？
我正在尝试播放一个非常小的音频文件 - 它的长度大约为 0.05 秒，并且是一个未压缩的 .wav 文件。
现在，我正在使用 AVAudioPlayer 来播放声音。
我打算在旋转器旁边高速播放声音，就像《The Price Is Right》或《Wheel of Fortune》一样。如果我实例化循环计数为 100 的 AVAudioPlayer，它确实会按照我的预期非常快地播放声音。
然而，如果我在旋转器的每个“滴答声”上执行 [audioPlayer play] ，音频就会严重落后。我的猜测是，与设置高循环计数不同，[audioPlayer play] 需要在每次播放时完成音频剪辑内存的设置和拆卸。
有没有什么方法可以强制剪辑在内存中保留更长的时间？这是一种非常频繁的声音，因此在整个应用程序运行期间保持这种声音也可以。
I'm trying to play a very small audio file - it's roughly 0.05s in length, and it's an uncompressed .wav file.
Rgiht now, I'm using AVAudioPlayer to play the sound.
I intend to play the sound with high rapidity alongside a spinner, a la The Price Is Right or Wheel of Fortune. If I instantiate the AVAudioPlayer with a loop count of 100, it does indeed play the sound very rapidly as I'd expect.
If I execute [audioPlayer play] on each 'tick' of the spinner, however, the audio falls terribly behind. My guess is that, unlike setting a high loop count, [audioPlayer play] requires complete setup and teardown of the audio clip's memory for each playback.
Is there any way to force the clip to remain set up in memory for a longer duration? It's a very frequent sound, and as such would also be okay with keeping it up during the entire app run.

如果您依赖于更精确的计时，您可能需要尝试使用其他声音 API 之一。 Audio Unit RemoteIO 很复杂，但可以最精确地定时播放未压缩的声音。 OpenAL 和音频队列是另外两个选项。
