One of the smaller but very handy features we added in Audition 2 was the ability to mix down your multitrack sessions and send them directly to the CD view for burning. That means you can do things like space out your CD tracks exactly as you'll want them to be heard, complete with crossfades and spacing, using all the tools the multitrack view puts at your disposal. Click through for the how-to.
First, lay out your songs on tracks in the order you want to put them on the CD. Put each song on its own track and create fades between them. Or you can arrange them with empty space between each song. After you tracks are arranged, add markers where you want each CD track start and make sure the markers are of type "CD". (Right click on a marker to change its type, or show the Marker window in the View menu.)

Next, go to File->Export->Mixdown and save the whole session as a .wav file. In the export options set the lower-right setting to "Insert Mixdown Into CD View" and click OK. Audition will mix the file down including crossfades and any effects you have applied.

The next thing you'll see is the Markers options dialog. Make sure to select "Add Multiple CD Tracks using Track Markers" so that the CD View will split up your multitrack mixdown into the proper CD tracks.

And that's it! Your CD tracks are now arranged, ready to burn, complete with crossfades or whatever other multitrack features you want to apply to the process.
