The second thing to consider when creating a master file is which Audio Format or Audio Codec you should use. Once again, in the Render As page of Vegas Pro 11, you will find a wide variety of audio formats to select from. To access the audio formats you need to have an audio track with some media on it and solo the audio track prior to selecting the Render As function. That way the audio formats will appear in the Render As window.
This allows for audio compatibility with some of Sony's earlier portable audio devices such as the Memory Stick Walkman and the Sony MiniDisc player.
