ios - 为 AVFoundationAudioSettings 设置 AVAudioTimePitchAlgorithmVarispeed

Question

根据这些docs ，我可以更改 AVAudioPlayer 的某些设置，包括 AVAudioTimePitchAlgorithmVarispeed 设置。我将如何设置这个值？我需要继承 AVAudioSetting.h 吗？

Answer 1

如果不需要使用AVAudioPlayer，可以使用AVPlayer

AVPlayerItem *playerItem = [AVPlayerItem playerItemWithURL:url];
playerItem.audioTimePitchAlgorithm = AVAudioTimePitchAlgorithmTimeDomain;
AVPlayer *player = [AVPlayer playerWithPlayerItem:playerItem];
[player play];
