I push this method every chance i get.
Make a Compressor droplet. Its easy.
Open Compressor. Look in the Presets pane. Open the Folder called Audio Formats. Select AIFF 48/16.
In the File menu select “Save as Droplet”
Put in on your Desktop or anywhere else convenient (even drag it to the dock…or the sidebar or top of a Finder window).
Now converting a bunch of CD tracks is a simple drag and drop operation.
Using the Destinations pane, you can select to have them end up on your media drive.
