Hello all,
 
I need some help figuring out how to get rid of this annoying noise at the end of my exported file.
 
I created a piece designed to loop. It loops fine in Sonar X1. But when I select the 24 measures that I want to export, it renders a tiny little pop or tick sound at the end of the loop, which of course wrecks the whole "seamless" loop concept.
 
Any clues on how to export without creating this noise? It seems to happen any time I end an exported file with anything other than total silence.
 
You can hear this bad behavior at the very end of 
 
Thanks in advance for any help or suggestions. I would prefer to stay within Sonar rather than having to clean these up outside the program.

Oh well, it won't let me post a link.

Is Snap to Nearest Audio Zero crossings checked in preferences > customization > snap to grid?

Yes it is. Does the snap on/off button need to be enabled for that to be in effect?

You can snap to zero crossing or fade ends of the clips. Many people do both.

Yes, you have to enable snap for it to work. When you have the now-time zoomed way in you should be able to see it jump from zero crossing to zero crossing.

If you're using the sample to loop in other software/hardware you'll need to ensure that the file itself has a matching start/end, with no sudden step in the wave form.  This is easiest to do with a simple wave editor outside of Sonar. 

I just add a really short fade in or fade out if needed. A few milliseconds is usually sufficient, and if it's a fade out, no one will ever notice...

Another thing which will cause this are reverb tails which didn't get to finish playing when you stopped the transport before exporting the audio.
 
to resolve this from happening, let the song finish playing all the way to the end and then stop it and then export.
 
this doesn't happen all the time, but it will sometimes cause a very audible sound at the beginning of the wave file that was exported.

Thanks to all for your comments. It was the audio zero crossing issue that I had to learn more about and deal with. Ultimately, after trying to fix it within Sonar for a day or so, I finally gave in and downloaded the SoundForge Pro trial and fixed it in about 2 minutes.
 
Thanks again!
