Actually, you're worrying about nothing here. What you say is true for a 
traditional mixer, but it is very difficult to make Sonar's audio engine clip 
internally.

Here is an experiment.

Take one of your tracks that is very hot, and turn it up so that the meter 
registers 0DB. You might heare clipping.

Now, turn down the master bus. The clipping goes away.

I don't fully understand how this works, but Sonar has internal headroom 
between the tracks and buses. Clipping the tracks isn't so bad, and, in many 
cases clipping the buses won't result in any sort of clipping that you can 
actually hear.

When you mixdown, though, you're saving a version of what was heard at the 
master bus, and, if that clips, there will be clipping in your two-track 
version, so it is important to be sure that the master bus doesn't clip before 
exporting audio/performing a mixdown.

So, in most cases, you don't need to worry about individual track meters going 
over 0DB. At least, the playback meters, that is. Record meters that clip are 
always a bad thing.

Len, yes there will be clipping.
If you have several tracks recorded, and there all just below 0 db and you send 
them to a master buss, it's like too menny folks trying to get through a door 
at the same time.
So by lowing the db level for each track is like taking some weight off the 
folks, making them skinnyer.
Now they have a better chance of getting throu the door.
For me, I try to keep the loudest track of my projecst somewhere around minus 2 
or 3 db.
This gives you some head room to work with.
Then adjust the other tracks around the loudest track to obtain a mix that 
satisfys you.
So if you don't use the Master bus for any thing else, it's usually a good idea 
to have one set up to monnor the over all peak level.
If you have a good mix and you have db level over 0 in the master buss, Lower 
the volume level for each track the same amount.
By the way, there's no such thing as a silly question.

Cheers!

Mark
