来自AVPlayer对象的AudioQueueLevelMeterState

Question

是否有可能以某种方式从AVPlayer中提取队列，因为从队列中可以提取像AudioQueueLevelMeterState这样的对象，或者有关频道号码的信息，可以在播放声音的同时在场景中绘制一些漂亮的动画，这要提前感谢。

Answer 1

AVPlayer is at a higher level than AudioQueue . AudioQueueLevelMeterState only offers mPeakPower and mAveragePower .

If you want detailed values for a nice animation, you'll need to go down to the actual float or integer values of the captured audio buffers themselves.
