Lets you choose from presets that you have already saved in Audacity (see below). In the image above, this option is grayed out because no user presets have yet been saved.
After you have made adjustments to the settings for the tool, you can use this option to save these settings for later use. When you name the preset you may choose the name of an existing preset and thus update it.
Deletes any user preset that you may previously have saved. In the image above this option is grayed out because no user presets have yet been saved.
The "Defaults" Factory Preset lets you reset the effect to default settings. For most built-in effects and all plugins shipped with Audacity, "Defaults" is the only available Factory Preset. Third-party plug-ins may offer multiple named factory presets which you can choose from.
Imports presets which you have exported using the Export option (below) on this or other machines or which you have exported from other software that supports a compatible preset. Available only for VST and Audio Unit (Mac) effects.
All plug-ins (except Nyquist) have per-effect options accessed by this menu for one or more of Latency Compensation, Graphical Mode or Buffer Size. If there are no options available (as in the Normalize image above) then this menu item will be grayed out.
