AVAudioPlayer是从磁盘流式传输文件还是将其一次全部加载到内存中？

Question

I want to play very long audio files of up to an hour. AVAudioPlayer seems to be the easiest solution. But is it also efficient or does it load the whole file into memory before playing?

Answer 1

Apple's doc for AVAudioPlayer say:

An instance of the AVAudioPlayer class, called an audio player, provides playback of audio data from a file or memory.

Applerecommends that you use this class for audio playback unless you are playing audio captured from a network stream or require very low I/O latency.
