Landmeter Posted April 16 Share Posted April 16 Hi there, I am trying to do a crossfade on a surround file. It shows up visually, but the problem is that it only fades out the first region, but it doesn't fade in the second region. The second region pops in at the end of the crossfade. This is of course unexpected behavior... Does anyone know if this is a bug? Any help would be greatly appreciated! Best Regards Quote Link to comment Share on other sites More sharing options...
polanoid Posted April 16 Share Posted April 16 Just tried this here and can't replicate that behaviour. Which Logic version are you using? Quote Link to comment Share on other sites More sharing options...
Landmeter Posted April 16 Author Share Posted April 16 Thanks for your reply! I am using the latest version 10.8.1 I tried to do the same in a new project, but it was the same behavior... Quote Link to comment Share on other sites More sharing options...
polanoid Posted April 16 Share Posted April 16 Could you post the surround file this happens with? Quote Link to comment Share on other sites More sharing options...
Sir Hannes Posted April 16 Share Posted April 16 Hi Landmeter, try to delete the crossfade plus the curve numbers. Then do it again. I work a lot with crossfades and this happens many times without a reason I know. But this little workaround helps. If not, cut the end and the beginning of each file and bring them together. At least here this works then. Quote Link to comment Share on other sites More sharing options...

As far as I understood the OP can even reproduce this in a fresh new project, so this seems to be a different issue? 14 minutes ago, Sir Hannes said: If not, cut the end and the beginning of each file and bring them together. The regions in the screenshot don't overlap, so the OP seems to have done that already (or used No Overlap Drag Mode in the first place) Quote Link to comment Share on other sites More sharing options...
Sir Hannes Posted April 16 Share Posted April 16 Ah see, ok. for the 2nd: I do not mean overlapping audio. I mean "cut out some of the meat which might causes the audio engine to produce that bug" - Then bring them together. Then do the crossfade.

Landmeter Posted April 16 Author Share Posted April 16 Hi Hannes and polanoid There seems to be a problem with the channel count. When I use a regular 5.1 (six channel) file, crossfades work fine. What I am using is an 4-channel ambisonics file. This is apparently causing the problem... 1 Quote Link to comment Share on other sites More sharing options...

That's why I proposed sharing the audio file (or any file this is happening with). As it's reproducible for you you should also report it via Apple's feedback page 3 minutes ago, Sir Hannes said: Ah see, ok. for the 2nd: I do not mean overlapping audio.

The screenshot shows that both regions reference the same audio file, so, no, not a feasible workaround here Quote Link to comment Share on other sites More sharing options...

If it is a atmo, and thinking on surround/ ambisonics, these are often atmos, then it might be a workaround. 🙂 Edited April 16 by Sir Hannes Quote Link to comment Share on other sites More sharing options...
Landmeter Posted April 16 Author Share Posted April 16 It is a large file so I bounced a portion to a surround PCM. Using this bounce there were no problems with crossfades. So I guess it is a problem with the source files. They were recorded on the Zoom H3-VR Quote Link to comment Share on other sites More sharing options...

Landmeter Posted April 16 Author Share Posted April 16 I just tried it with different files record on the Zoom, and yes same problem Quote Link to comment Share on other sites More sharing options...
polanoid Posted April 16 Share Posted April 16 (edited) I just tried with a file from this package https://github.com/ambisonictoolkit/atk-sounds/releases/tag/v1.0.0 (EDIT:seems to happen with all files in that package) and indeed I see the same issue here. So, an issue with Ambisonics files in Logic. Could you report it via Apple's feedback page? Edited April 16 by polanoid 1 Quote Link to comment Share on other sites More sharing options...
Landmeter Posted April 16 Author Share Posted April 16 Will do! Your help is much appreciated! 1 Quote Link to comment Share on other sites More sharing options...
Landmeter Posted April 17 Author Share Posted April 17 For now a simple, but tedious solution is placing the regions on different tracks and individually fade the regions out and in. Quote Link to comment Share on other sites More sharing options...
