Play some of the major players involved in recording alone, mixed with normal music file playback, recording or delete. For developers play a very large part of the difficulty, because the recording process is normal and will put together a music file, then it makes it difficult to extract the audio file to play alone. Since the function is too complex following a brief explain the basic process of recording, development-related issues may have further exchanges.
