Can someone figure out how to locate (and remove) the white noise sound in this totally empty project (iClone 7.83) I attached?
It starts at frame 0 and ends at around 600, it can be heard even when dragging cursor on the timeline, but there is nothing :alien:

Does it appear only in this particular "empty" project or in every "new" project you start?
I had this a long time ago, it started suddenly and after a few days it disappeared.
To be honest, not much interest to test this, don't want it to appear again.
I have no clue what caused this, but iClone has some strange behaviour with audio once in a while...

I don't remember any other project apart from this. Even with this one, I noticed only few days ago, wearing the headphones (since I'm rendering as png sequence, sound is not what I'm paying attention during work) so I removed everything in order to get this empty project and locate the source of this sound, to no avail.

Yeah, weird. The only way to salvage the project is to save all animations from it, then do Remove Scene Animation > Keep First Frame. Reapply animations.

it's a rogue audio file stuck in the area of memory where I have said there's a memory leak since iclone 3. I don't think RL knows how to fix this memory leak else they would have already, it also affects the animation system too, like if I do a complicated keyframe animation and the gimbal falls off center, the problem carrys over to new projects until I reboot the software. this is one of those anomaly issues we just have to work around because it will never be fixed until iclone is basically reconstructed from scratch.
I wonder if a memory flush / parameters reset option is possible, maybe addressing this memory issue isn't easy, but I wonder if simply flushing the memory and resetting parameters will be the 2nd best fix than rebuilding the code from scratch ? at the very least it would give the user a clean project file to save vs a permanently corrupt file that has data in unreachable places.

The noise clip is actually embedded into the project. It is possible to remove it in binary editor (you have to locate an *offensive* part first within the code :hehe:).
I found it in your clip by comparing original file with the one I removed animation from and saved. Then replaced it in original file. It worked.
Send me the original file if you want to and I'll try to remove the noise clip from there without affecting other animations. No guaranty though this method is going to work for a complex project.

nice find 4u, thanks for sharing that - it confirms my hunch that things do exist in inaccessible areas of memory to users. I bet that area of memory is also whats causing iclone and cc3 to run so sluggishly, saying this because when I used wise memory optimizer - http://www.wisecleaner.com/wise-memory-optimizer.html iclone and cc3 were running a lot more stable ...unfortunately I had to stop using wmo because it was negatively affecting other areas of my pc. ( i may have to retest that theory tho, i've since discovered new stuff since I last tried it )

Thank you all for your kindness :)
It's not worth the time and effort, though, because, as I said, I'm rendering as png sequence, so project soundtrack itself doesn't matter in the final "product", since it will be done in video editing.
Because I tried to add/remove 700 frames and the noise was still present, I'm starting to think it's not a rogue sound sequence, but some sort of soundcard open/close operation (which would explain the white noise behavior). I was thinking to open a bug report to RL but I don't think it worth the effort, honestly.
Thanks again! 🤗

i thought that was the case too - that sound is familiar like when the record input is too looud and records system noise , but if you listen to it carefully the pattern is exactly the same every time you play it, so it's a sound file because computer whitenoise is random based on whatever it's calculating at the moment. ( sound stuffz is my thing lol )
For me, I'm happy this was brought up tho, in the bigger picture this area of memory causes a lot of issues for both cc3 and Iclone and your project may have given us an opportunity to show the developers exactly where. :)
Your project succesfully trapped the proverbial ghost in the machine hehe!!
