When to use Compare Settings
In some cases, you might not know what settings of a module will give you the best, most transparent results. By hitting the Compare button instead of the Apply button, you can audition multiple settings of the same module and then audition the results side by side. While one group of settings is processing in the background, you can return to the module and try a different group of settings. Learning to use the Compare Settings tool can save you from having to apply and undo a process multiple times just to find the right settings, making it a valuable time saving feature.
List - Each time settings are sent to the window, a new list item is created, by default titled "Settings 1," "Settings 2," etc.
Preview - to hear (and see) the result of an item in the list, select that item and hit Preview
View Settings - shows the modules settings used for processing
Remove - remove an item from the list
Rename - allows you to rename items with more descriptive names
Apply - apply the selected list item to the audio file
