How do you record audio directly from iOS?

Is there a way to record device audio on iOS?

• AVAudioRecorder allows the recording of external audio. However I wish to record the audio made by my application as opposed to external audio. Is this possible to do on iOS?

• Answer:

  What frameworks are your application using to make audio?  If you're using a lower-level framework like Audio Queues or Audio Units (both part of Core Audio) or OpenAL, then you have buffers of samples that you could write out to a file with Audio File Services or ExtAudioFile. If you're using a high-level framework like AV Foundation, Media Player, or an <audio> tag inside a UIWebView, then it's probably not going to be possible, because you don't have access to the audio data. There is not, as far as I know, any way to do something like the Mac's "Soundflower" to capture all system audio, since Soundflower is basically a virtual device for audio output, and third parties can't write device-level software for iOS.
