Answer 1

As you have it at the moment you create the WaveFileWriter object, stop recording, then write nothing to the wav file. What you end up with is an empty file that will not be even slightly useful.

Create the WaveFileWriter first, before you start the recording. In the DataAvailable event handler for your recorder object write the received sample data to the WaveFileWriter. Then when you are done with the recording, dispose of the WaveFileWriter to finalize it.

Once you have done that you should have a valid wav file.
