Pops and clicks at end of loop

Hi,

Make sure "Search Zero Crossings" is switched on in the Audio window.

Besides searching for zero crossings, you can also put small crossfades between the end of one region and the beginning of the next region.

If it's in Apple Loop format, you can't crossfade (which is a drag), and you'll have to just experiment until you find a good end and start point on each region.

Did you have Drag set to XFade before and now it's set on Overlap or No Overlap? (upper right of Arrange window) Or is XFade on and your Overlap time in your preferences got set to 0? (Preferences -> Audio -> General)

I guess the other contributer and me are thinking of the same cause, that the cut at the end or beginning of each loop isn't zeroed. If it's not that, then I dunno...

e

Now that you have set the Search Zero Crossings parameter to On, you now need to readjust the region starts and ends so that the zero crossing search will take place on the regions in question (the regions that were previously added/created/adjusted while the Search Zero Crossings parameter was set to Off) .

So, are you getting regular clicks or just a click when you hit play? If you're getting regular clicks are they at regular intervals, or randomly throughout? Do they correspond with the splices or are they somewhere else? Does this happen with all your looped material? If so, what kind of looped material - audio, midi, apple loops? Does it happen when you solo non looped material?

Clicks when you hit play can occur because Logic has a bug where it "finishes out" the sound, including reverb tails, from when you last stopped the playback. If you play for a second in an empty part of the track until the project is silent, before you play or bounce from a different point, you won't get this.

If clicks are happening more randomly throughout the track, it might be something iLife has done with your audio driver. As simple as your buffer being turned down too low, or something more complicated like a need to reinstall the driver for your audio interface.

Hope that gets some wheels turning..

That's gotta be the zero crossing stuff. Select all your audio that's clicking, and using the window in the upper left of the Arrange window (sometimes you have to open it with the little triangular arrow), add Fade in and Fade outs of about 2. If your audio loops meet you can also select all the audio regions that are clicking, except the last one in the song, and give them crossfades of about 3 or 4. Then add a fade out to the last region and a fade in to the first.

These fade times aren't noticeable, they just eliminate the clicks.

I know you haven't had this problem before, but this is standard operation for me, otherwise I'm guaranteed clicks and pops. The zero crossing thing that someone suggested is not something that I would use because with loops I usually need things to end exactly on the bar lines, and that setting automatically changes the start and end points to the nearest zero.. I would end up with overlaps and gaps between regions.

Try this, if it works at least you know what's causing the problem. If you don't like this solution you can try to figure out why you didn't need to do this before. I think you've just been lucky in the past! I need to do this often enough that I put these fades on all my regions, easier & faster then sitting there and listening to everything for clicks, with no audible changes to the recording.

Have you tried creating a new project, and importing the files from the problem project to it?

Have you tried selecting all regions and adding a fade in of 2-3 ticks? (using the window in the upper left)

You have to at least try this to see if it is the zero crossings issue.
