It is necessary to specify the soundfiles for encoding (see Figure 5-3).
To select a soundfile for one of the 6 channels, click on the button on the left that corresponds to the channel you want to load. This will bring up a browse window (see Figure 5-4).
Navigate to the directory that has your soundfiles, and double-click on the soundfile that you've chosen for that channel. The filename that you've chosen will now appear to the right of the browse button.
You will usually specify soundfiles for all 6 channels if you are encoding 5.1 Surround. If you don't specify a filename for a channel, SurCode will encode silence into that channel.
