The is no public iOS API that will allow you to record all internal sound that an app or the device can make. Only certain types of internal sound can be recorded, for instance sounds produced by an app using Audio Queues or the RemoteIO Audio Unit.
没有公开的 iOS API 可以让您录制应用程序或设备可以发出的所有内部声音。只能录制某些类型的内部声音，例如使用音频队列或 RemoteIO 音频单元的应用程序产生的声音。
For recording external sound, Apple's SpeakHere sample code might be appropriate.
对于录制外部声音，Apple 的 SpeakHere 示例代码可能适用。
