AVAudioRecorder - 继续记录到文件的用户停止录制后离开应用程序，然后重新打开它 [英] AVAudioRecorder - Continue recording to file after user stops recording by leaving the application and then re-opens it

问题描述

可以这样做？如果没有，多远下来，对核心音频，我需要去（我应该用什么方法记录代替）？

Can this be done? And if not, how far down towards Core Audio do I need to go (what method of recording should I be using instead)?

我注意到AVAudioRecorder的行为是覆盖一个文件，如果找到一个在当你要求它重新录制提供的路径，所以我知道这是行不通的。我也好奇这个想法文件格式的限制。可以有效恢复的AAC或IMA4编码（我想记录使WAV和文件的长度甚至可能苹果无损望而却步）？

I've noticed the behavior of AVAudioRecorder is to overwrite a file if it finds one at the path provided when you request that it record again, so I know that's not going to work. I'm also curious about file format restriction with this idea. Can you effectively resume an AAC or IMA4 encoding (the length of the files I want to record make WAV and probably even Apple Lossless prohibitive)?

感谢。
