Chapter 40 Project Settings and Preferences 961
 Number of Undo Steps: Determines the maximum number of undo steps that are
retained.
 Store undo files in project folder: Activate this preference if you would like the edited
audio files to be stored in a sub-folder of the current project. This is switched on by
default if the project is saved with its assets.
 Global Undo File Path: All files (used by the Undo History) are saved into a global
location—a user-defined folder—if the “Store undo files in project folder option” is
not switched on. Click the Set button, and browse to the desired folder.
 External Sample Editor: You can use an external application for sample editing
operations, effectively replacing the Logic Pro Sample Editor. Click the Set button,
and browse to the desired application.
Surround Preferences
The Surround preferences are covered in “ Setting the Surround Preferences ” on
page 812.
MP3 Preferences
 Bit Rate (Mono/Stereo): The bit rates are selectable between 32 kbps and 320 kbps,
but default to 80 kbps mono, and 160 kbps stereo. These rates offer acceptable
quality and good file compression. If you can afford the extra file size, you should
select 96 kbps for mono, and 192 kbps for stereo streams. These will deliver better
audio quality. You can, of course, choose even higher rates, but the quality
improvement in bit rates above 96/192 kbps is minimal.
