When rendering an audio only project, I'm creating an mp3 file. When the mp3 is created, there is no audio at all. I've tried to save as a wav file, too, and have also rendered using different templates that are available. My Vegas Movie Studio version is 9.0a (Build 60), and I'm running Windows 7. Can you anyone please tell me how I need to render this project to properly create a mp3 file that I can use? Thank you for your help.
