AVAudioRecorder可以用于录制来自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

我想录制来自我的iPhone应用程序的音频.因此，在将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)播放音频之前先对其进行采样.

I'd like to record the audio coming from my iPhone app. 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).

我一直在尝试 的音频吗?

I've been experimenting with RemoteIO Audio Units. These seem promising. However they're pretty low level. Can AVAudioRecorder (or other "high-level" object) be used to capture audio coming from an iOS device?

推荐答案

据我所知，AVAudioRecorder无法做到这一点.您必须使用音频单元.

As far as I can tell, there's no way to do this with AVAudioRecorder. You must use Audio Units.
