AVAudioRecorder可用于录制来自iOS应用程序的音频吗？
[英]Can AVAudioRecorder be used to record audio coming from your iOS app?
问题描述
I'd like to record the audio coming from my iPhone app. 
我想录制来自我的iPhone应用程序的音频。 So after the background music and sound effects are mixed I'd like to sample the audio before it's played from the device's speakers (or headphones). 因此，在背景音乐和声音效果混合之后，我想在从设备的扬声器（或耳机）播放之前对音频进行采样。
I've been experimenting with RemoteIO Audio Units . 我一直在试验RemoteIO音频单元 。 These seem promising. 这看起来很有希望 However they're pretty low level. 然而，他们的水平相当低。 Can AVAudioRecorder (or other "high-level" object) be used to capture audio coming from an iOS device? 可以使用AVAudioRecorder （或其他“高级”对象）来捕获来自 iOS设备的音频吗？
