I recorded an acoustic guitar track in X3. There was a spot that I wanted to overdub so I set up comping and recorded several takes. I tried to use the comping feature but kept getting pops and clicks at the transitions. After getting frustrated I exported the track as a wave file and then imported it into Studio One. I did the overdub. Perfect take and transitions.

So what am I doing wrong in X3. I never had this problem with earlier versions of Sonar (pre X series)

I find it ironic you're pimping Studio One here, today!  Ironic in that just for the heck of it, yesterday I downloaded the Presonus Studio One 2 (??) demo and spent the evening with it.  It was free, I had some time, and like to know wtf people are talking about when it comes to other DAWs.  Done Cubase, Logic... friend has Ableton (interesting, love the minimilistic fonts/knobs et all but ooooodles of $$$$ and not deap)  After looking at the menues, trying to work on an idea, searching their help guidance.... I just shook my head... and closed it down.  Was up till daybreak in my usual blissful state, creating wonderment...lots of "comping" btw, and can't ever imagine opening the demo again.  I don't mean to be a jerk, but I'm really spoiled.  I don't know how to do half of what X3 offers but I can say S1/X3= Crude vs Elegant or, put another way, shallow vs deep.  Now, just to be clear... I'm no technowizkid on DAWs... I'm a singer/songwriter who has lots of tools... and X3 allows this simple artist to wield them in ways I'd never dreamed.  If I ever get the deep part down, I'll be dangerous!  But stuff like comping.... like solar energy to me..."perfect"
 
As to your presumed problems with comping...I think it's pretty well unanimous that comping works like a charm.  It's the awesomest most intuitive creative tool I can imagine and works flawlessly.  Suggested inhancments aside, it's amazing.  Watch the videos...so simple and elegant, someone would really have to be a duffus to be doing something wrong...then again, getting such good results with that tinkertoy program which works "flawlessly"...to do what X3 does (and Studio One DOESN'T) do...seems a bit far fetched to me.
 
I know I haven't been very helpful, if that's what you wanted... but you did ask in a rather flamey way... and you did catch me at my LOL about all the Studio ONE blather which for some reason shows up on this Sonar forum periodically...
 
 

No flame intended so I'm sorry you took it that way. I'm trying to work through X3 and need a little help. I had S1 to compare so I did. Now I want some assistance from the sonar community. I'll assume you don't reflect the majority of the group. ;)

hi!
 
trying to help but don't know your system ... so I can only make some educated guesses here ...
 
first of all, I would check my ASIO buffer settings (you are using ASIO and not some cheap audio interface, right?) - i like to keep them small during recording but increase buffer size when editing/mixing ... small ASIO buffers is #1 source for drop outs...
 
next, if you have a lot of takes recorded during your overdubbing, you might get clicks and pops because your hard drive is not fast enough; remember that sonar needs to read every single take from the disc (even the muted ones) because it cannot know upfront which one you will mute/unmute via the comping process ... so throw away the rubbish takes and just keep the best 5+ before going into comping mode ...
 
if that doesn't help, pls shed more info
 
all the best
 
 

I don't think this is a buffer issue. The click is happening at the transition from the end of the first take and the beginning of where the overdub begins. It happens again at the end of the overdub/beginning of the first take. I tried adjusting fade-in/fade-out but no luck.

Does it still click, if, say, you export the track (with the clicky comp left in) to a wav? It would at least indicate if it's the DAW doing it internally, via some sort of start-stop action, or if it is inherent to the way it the DAW is making wave crossovers.
 
If it's a simple example, you could post a link to your project and some of us might take a look at it.
 

Set up the snap to grid settings and use that. It automatically makes the cut at a ZERO crossing of the wave. When you try to do this free hand, you will get clicks just about every time.
 
I have done edits where I removed several measures of a solo..... (4 measures) and by setting the snap to grid to measures, then making my cuts, (exactly on the measure line automatically) I deleted the measures and slid the others over to close the gap and the playback was perfect.
 
This also works on other resolutions such as quarter, eights, and sixteen.
 
Depending on the instrument, I will often have several tracks and pick the parts of a solo to comp one complete solo from the many...  Picture below is piano fills comped from several takes. Fills are in the first verse of The Best Christmas on my music page.
 

 
Notice that I have SNAP TO turned on and set to quarters in this pic for editing.

Thanks to both SuperG and Guitarhacker. I'll try both suggestions tonight and see what happens. I'll let you know the results.

I was thinking the "Zero Crossing" setting also. Try that first. If not that, check buffers.

Just to be sure it's not the project itself, start new project and do some comping on that one and see if you still have the same problem.
