title: Xamarin.Android splitting and concatenating audio files
body: <p>I'm currently working on an application which records audio and save the file. Now I'm searching for a solution to split the audio file from a position (for example: split in half and have 2 audio files) and register another audio file. In the end I need to concatenate all the audio files (2 or more files) to create one single file. 
  I need to do all this in Xamarin.Android.<br>
  Did anyone did this sort of things? Is it possible to do this without any library? If not, what library should I use in order to do the cutting and concatenating of the audio files. 
  I would appreciate any response.</p>
