How to greatly expedite audio export
Go to Edit/Preferences/Export and turn off normalization. Normalization isn't a good thing anyway— it makes a full orchestral pieces with a huge tutti to quiet and it makes lighter scoring too loud—but this process also takes a very long time. If you are saving online with audio, or exporting audio, the process goes much faster with normalization off. I know that some people value this function, but I just wanted to help out some users that would like to export audio more quickly.
