Audio "pop" or "tick" at end of exported wav
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!

I was going to say this is a good task for a wave editor.
Wavosaur is free, and Gold Wave has a demo that is an honor system and is only $40. Wave lab Elements is very powerful and only $90. Wave lab is faster with mouse editing than Sound Forge,, less clicks to do the same task.

I'm curious, what did you need to do in Sound Forge to get the loop working the way you wanted? I'm trying to think of a function Sound Forge has that would make it possible whereas it wasn't possible in Sonar. I have and use Sound Forge, but I use Sonar all the time to make loops. The only time I HAVE to use a wave editor is looping the sustain in notes for sample libraries. Unfortunately in Sound Forge, the loop points are not always recognized by SFZ players - it's a known bug that has existed for a while. Wavelab doesn't have this problem, but I find it harder to hit the right loop points than with Sound Forge. So I create the loop points in Sound Forge, then bring into Wavelab (which recognizes the loop points), then save from Wavelab.

For some reason, I was really struggling to find the zero crossings in Sonar. Even with snap enabled, it didn't seem to be giving me the results I wanted. Since I had heard so many people talking about using SoundForge, I decided to give it a try. I was just impressed that the first time I touched the software it did exactly what I needed. It snapped to zero crossings and I shaved a little of the beginning and the end. And suddenly I had a seamless loop.
Like you said, it didn't bring any new functionality to the table, it just seemed to work better, or at least more intuitively.

IMHO Sound Forge is very underrated because it doesn't have a fancy UI, but its functionality and ease of use is really quite something.
I wrote an article on Sound Forge tips and tricks for harmonycentral.com, but it hasn't been published yet. You might want to watch for it...
