Is there a way to pause the recording and start after a while.
Short answer: no
Once you are recording the only possible actions are stop and reset.
There is no pause() functionality when recording media. I would try conjoining two separate audio files together once the user hits your "stop" button in the app. Either that, or try to find a way to write to the same file stream after using the stop() method.
