System information
2.  Choose a command from the submenu to specify how to  treat the channels in your file.
For events that use multichannel audio:
Item Description
Channel x Treats the event as a mono file using the audio from the channel you 
choose.
Channels x/y Treats the event as a stereo file using the audio from the channels 
you choose.
For events that use stereo audio:
Item Description
Both Treats the  event as a normal stereo file.
Left  Only Creates a   mono event using only the left channel of your media file.
Right  Only Creates a  mono event using only the right channel of your media file.
Combine Creates a   mono event by mixing the channels of your media file. 
After mixing the  channels, the amplitude is divided by two to prevent 
clipping. 
Swap Exchanges  the right and left channels in a stereo file.
Opening Events in an Audio Editor
The Vegas Pro timeline is a nondestructive  editing environment, which means that the original source files 
remain  unchanged by any editing done in the software. Edits that modify the actual   source media file 
(destructive edits) may be performed in a separate application  such as Sound Forge software from Sony 
Creative Software Inc. 
From the Tools menu, choose Audio,  and choose Open in  [editor name]  from the submenu to start your 
sound-editing application and modify the  selected audio event using the editor specified on the Audio  tab 
in the Preferences dialog.
1.  Select the event you want to edit.
You can select multiple events to open each event in a separate window   in the sound editor.
2.  From the Tools menu, choose Audio,  and choose Open in [editor  name]. The editing application is 
opened with the event's media.
3.  Edit and save the file.
After you have edited and saved the file, Vegas Pro  automatically detects the updated file and 
updates the event in the project.  However, if you change the media file’s name or location (by using 
Save  As), you must import the edited (new) file  into your project. For more information, see "Import 
Media" on page 98.
