有没有办法在iPhone上录制设备音频？ [英] Is there a way to record device audio on the iPhone?

问题描述

AVAudioRecorder允许录制外部音频。

AVAudioRecorder allows the recording of external audio. However I wish to record the audio made by my application (through numerous AVAudioPlayers), is this possible on the iPhone?

推荐答案

如果我的应用程序（通过许多AVAudioPlayers）录制音频，您想要录制您的iOS应用程序的声音，您必须使用低得多的杠杆API，如音频单元RemoteIO或音频队列与原始PCM音频样本。

If you want to record the sounds your iOS app makes, you have to use a much lower lever API, such as Audio Unit RemoteIO, or Audio Queues with raw PCM audio samples.
