The AMR codec was removed from iOS in version 3.2 (I think). Ah no, 4.3 (thanks, Eric D.). The only reference I ever found to this was in the dev forums (login required).

AMR编解码器已从版本3.2中的iOS中移除(我认为)。啊不,4.3(谢谢,Eric D.)。我发现的唯一参考是在dev论坛(需要登录)。

The strange thing is, while kAudioFormatAMR was removed in iOS 4.3, it looks like kAudioFormatAMR_WB was added to OSX 10.10 (Yosemite).

奇怪的是,虽然在iOS 4.3中删除了kAudioFormatAMR,但看起来kAudioFormatAMR_WB已添加到OSX 10.10(Yosemite)。
