nit: Comment to clarify how to configure the AudioWriter with a Session to use.

Done.

 
-  // Initializes the writer.
-  void Init(Session* session, const InitializedCallback& callback);
-
-  // Stops writing. Must be called on the network thread before this
-  // object is destroyed.
-  void Close();
-
-  // Returns true if the channel is connected.
-  bool is_connected();
-
   // AudioStub interface.
