推荐答案

是可以的.我建议下载此示例应用程序: http://zerokidz.com/audiograph/Home.html audioGraph .然后在启用麦克风的同时尝试使用AVPlayer播放音频文件.我发现这是可能的，但这取决于您要使用AVPlayer播放的音频的文件格式.

Yes it is possible. I suggest downloading this example app: http://zerokidz.com/audiograph/Home.html audioGraph. Then attempting to play an audio file with AVPlayer while the mic is enabled. I found that it is possible, but it depends on the file format of audio you want to play with AVPlayer.

例如，我发现如果您在44800hz处有一个InputCallback并尝试使用44100hz的AVPlayer播放音频文件，您将开始在InputCallback中收到错误.但是，如果您播放一个48000hz文件，它将可以正常工作.

For example, I found that if you have an InputCallback at 44800hz and attempt to play an audiofile with AVPlayer that is 44100hz, you will start receiving errors in the InputCallback. But if you play an 48000hz file, it will work fine.
