The default configuration tab in Figure 2-3 provides several different preset configurations of the codec. The Preset Configurations buttons allow the user to choose from the provided defaults. When the selection is made, the Preset Configuration Description box shows a summary of the codec setup associated with the choice made. If the choice is acceptable, the Load button can be pressed and the preset configuration is loaded into the codec. The user can change to the Command Line Interface tab (see Figure 2-4) to view the actual settings that were programmed into the codec.
