Time stretch without pops?

I'm having trouble getting time stretch to work as I'd like. Example: I want to nudge a guitar hit a bit to the right, it's early. The nudge is easy enough. What I then want to do is time stretch just the tail of the prior chord so it fills the space. I would expect to do this by splitting somewhere in the tail and then dragging it over. Problem is that I always get an audible pop at the split in the tail. I have tried every splitting method (zero-crossing, crossfades on & off, etc), and the pop seems to always be there. Grateful for any help. Thanks.

Timestretching does alter the samples enough to possibly create clicks where none were there after just splitting. Even when the split occurred on a zero crossing. I cure them with a tiny crossfade, sometimes I have to move it about a bit to find a good placement.

I wouldn't time stretch it t all I would take a small slice from the middle of the chord - before the end, move the end part to where you want it, then center the slice and use crossfading on both ends of the split - you may need to experiment with the position and crossfading a bit

Thanks. I've actually tried both of those algos, with the same result. What's odd to me is that, when I'm stretching to the right, the left side of the split is still affected. Pop on the right, in my example, is still a problem, but makes a bit more sense. Crossfade makes the pop quieter, but doesn't eliminate it, and introoduces a quick volume drop at the point (with the setting that makes the pop quieter). Should say, in dozens of attempts, the pops happened every time. And while it's not particularly relevant, other DAW software is able to accomplish split-and-stretch without pops. I see elsewhere that the split-to-transients scheme introduces pops, but that's a more complicated process for sure. So, would you say at this point it's just a limitation of the software? Thanks.

It's absolutely not the software :) I do this stuff all the time and it's no different to logic, nuendo and protools :) How about uploading the project and file in a zip, delete all other tracks except the clicking one and we can have a look at it for you. it might just be a misunderstanding with the way it's being used.

I put a very short example here: (I hope that's everything you need to recreate the project.) --- Sorry about the audio quality, I just recorded through my talk-back mic. You'll see that there's a bit going on in the project. A take under the main take, items grouped. One thing I discovered in making the test is that if I simply record 1 take, the pop doesn't occur. But if there's 2 takes tracked, the pop occurs, even if go back, ungroup the audio, and delete the unused take.

Your right couldn't do it without crossfade but I think with material like this I have always had to use a little crossfade on all the progs I use. maybe not, will let you know next time it comes up :) here's a version crossfaded, I used the equal power crossfade to stop the drop in volume and made fade as long as the timbre modulation to stop it sounding strange, not perfect but hope it helps.

It seems it is a bug yes :) I would add it to the full bug report section here.. as it will allow others to confirm it. Post the link to it on the standard bugs page asking people to confirm it as the above link is not seen on pressing the "new posts" button in the forum.

Ok, I'll add it. Feel silly, a bit: "Hi, glad to be here! Don't understand half of what Reaper does, but here's a bug I found!"

Don't be! ;) there were at least 3 things I really needed from my old DAW and they got put in within a few months :) same with bugs, this ones quite big for some people so I think you will actually gain respect for pointing it out and finding it! ;) Reaper really is a community and if your adding to it positively (which bug reports are) then it's all good!
