Re: The problem with RAW Audio wav file

You can use the High RAW Protune audio with Stereo Only, or with your video editor (I use Adobe Premiere Pro so I'm not familiar with Vegas). A free audio editor you can try is Audacity. It's takes some practice to really learn and get right, but it's a very good editor.

Re: The problem with RAW Audio wav file

Not sure what is happening with #1 but #2 I can answer.
The three tracks are each microphone. The two that appear empty have audio data, but because no auto gain control (AGC) has been applied to them in the camera, they appear blank. If you bring up the db or adjust the levels in an audio file editor, you can bring them to a usable level.
