In WaveLab make sure you have the marker toolbar visible.
For your first track, make sure the cursor is at the very beginning of the file.
Hover over the rainbow multicolored triangle on the marker toolbar and select it. That brings up the new marker dialogue.
Select "cd track start" marker type for the first one. (The quantize to cd frame will be grayed out on the first track, but this will be an important check box in the following steps because checking it will avoid sector boundary errors).
Now, you can either have wavelab auto name your files (track 01, track 02 etc...) or you can untick the auto naming box and use the etree naming convention. I will do the yourband2005-08-13d01t01 in the name field and then highlight it and copy the name to the clipboard. That way, when I name the next track, I just paste it in and change the last #1 to a 2.
Now, on to track 2.
Position the cursor to where you want the track to split.
Select the rainbow triangle on the marker toolbar again.
This time, select "cd track splice" (you can leave it on "cd track start" and it will automatically convert to a splice marker, but I am ocd like that)
Make sure you have the "quantize to cd frame" box checked and it will locate the sector boundary for a perfect track change.
If you drop generic markers, wavelab just leaves them where you position the cursor. Then when you split into separate tracks, you get sector boundary errors. Using cd markers with the quantize function checked, wavelab will reposition the cursor to the closest sector boundary (don't worry, it is only miliseconds off of where you put your cursor)
Paste in your track name and you're off.
Once you drop the cd markers, you can slide them where ever you want and wavelab will keep them aligned along sector boundaries.
Now that the cd is tracked out. I open the audio cd burning dialogue.
file>new>basic audio cd
select the little black tringle at the top left of the dialogue box and then select the "add tracks" option.
Browse to your file and double click.
Now you have all tracks in the burning dialogue.
Punch the copy protect (little key icon) to deselect all copy protection checks.
From here you can burn the cd straight out by pressing cd>write cd OR
you can press cd>save each track as a separate audio file (and it will write all files on sector boundaries as separate tracks while keeping your original file intact)
Now that you have all the tracks saved separately and named according to etree convention, you can drop them into the flac front end and flac 'em up.
Hope that helps. Certainly, there are other ways to do it, but I have found this method to be the fastest and most efficient while leaving the original file intact.
