Lancelot Chan Posted February 18, 2023 Share Posted February 18, 2023 (edited) https://www.youtube.com/watch?v=uTfYEPNIliA The audio becomes clipping in 13.10 and 13.11, through repetitively auto normalization by opening the project again and again. 13.09 doesn't have this problem.

borate Posted February 18, 2023 Share Posted February 18, 2023 Not seen here in 13.11. Loaded a file, saved it, loaded the same project again and again. Level stayed the same. Upload and share the file in question, please. Link to comment Share on other sites More sharing options...

borate Posted February 18, 2023 Share Posted February 18, 2023 Same in 13.09, when reloading a saved project. But, if the exported result is loaded the audio bumps up. That's probably not right, as it's already been normalized. Seen in earlier versions as well. Unchecking the "auto normalize" box in OPTIONS | MEDIA should overcome it. Reported.

Lancelot Chan Posted February 18, 2023 Author Share Posted February 18, 2023 Thanks. Yes, that bumps exceed the clipping limit. Link to comment Share on other sites More sharing options...
Lancelot Chan Posted February 21, 2023 Author Share Posted February 21, 2023 Just confirmed that 13.12 still has the same problem. Link to comment Share on other sites More sharing options...
borate Posted February 21, 2023 Share Posted February 21, 2023 Can't spot the problem here. With "automatically normalize..." enabled for the initial save, each subsequent load of the project doesn't change the audio levels. However, if an exported project is reloaded, then audio will bump up if "auto" isn't disabled. May require cache to be cleared as well. Reloading of an exported file isn't often needed. Still, audio that's once been normalized probably shouldn't be normalized again. https://www.nch.com.au/software/bug.html?software=VideoPad Link to comment Share on other sites More sharing options...
Lancelot Chan Posted February 21, 2023 Author Share Posted February 21, 2023 https://www.youtube.com/watch?v=Bvyl06pCWSQ This is how it is like on my end. I started from installing the 13.12, then load the project up, the first time it was fine. Then I made a new project to clear screen, then load the same project up again. This time, the audio file is super-normalized. The third time is the same. Link to comment Share on other sites More sharing options...
borate Posted February 21, 2023 Share Posted February 21, 2023 Suggest not using 13.12 as some audio issues are being addressed. Cannot replicate your results here in 13.11, following what seems to be the same procedure... buzz.mp4 Link to comment Share on other sites More sharing options...
Lancelot Chan Posted February 22, 2023 Author Share Posted February 22, 2023 Would it be because my audio files were not from the video but from the NCH library? Dunno if it makes any difference. Link to comment Share on other sites More sharing options...
borate Posted February 22, 2023 Share Posted February 22, 2023 Ran a test with a bell from the NCH library. Sure enough, simply reloading a saved project bumps up the audio. No need to clear the screen. Link to comment Share on other sites More sharing options...

borate Posted February 22, 2023 Share Posted February 22, 2023 See what 13.14 does for you. 32-bit, with the usual beta caveats. Link to comment Share on other sites More sharing options...
Lancelot Chan Posted February 22, 2023 Author Share Posted February 22, 2023 13.14 no longer repetitively normalize a file. However, there are 2 problems. 1, it still over normalize and make clipping sounds. I include the captured file of 13.09 vs 13.14 here. You can see the 13.14 one shows clipping. http://www.rsw.com.hk/1309.jpghttp://www.rsw.com.hk/1314.jpg Another problem is when you zoom in the 13.14, after certain level of zooming the audio files will display as flat lines!

borate Posted February 22, 2023 Share Posted February 22, 2023 Not seeing level change or clipping upon project reload in 13.14... Original load... Reload... But the zoom issue is evident. Work in progress. Link to comment Share on other sites More sharing options...
Lancelot Chan Posted February 22, 2023 Author Share Posted February 22, 2023 Well, once again, those audio files I showed were from NCH library, not from videos. Maybe it shows a difference. Link to comment Share on other sites More sharing options...
borate Posted February 22, 2023 Share Posted February 22, 2023 Doesn't seem to in 13.14, using an NCH bell sound... Original load... Reload... Link to comment Share on other sites More sharing options...
Lancelot Chan Posted February 22, 2023 Author Share Posted February 22, 2023 Does the level compare the same to 13.09? Not in my case. Link to comment Share on other sites More sharing options...
borate Posted February 22, 2023 Share Posted February 22, 2023 Same. NCH bell sound in 13.09... Share the file that you tested. Link to comment Share on other sites More sharing options...

borate Posted February 23, 2023 Share Posted February 23, 2023 Version 12.14. First load (cache empty)... 2nd load... 3rd load (after clearing project but not cache)... 13.09.... Link to comment Share on other sites More sharing options...
Lancelot Chan Posted February 23, 2023 Author Share Posted February 23, 2023 Yes, it doesn't increase level in repeat load but the level it loads is clipping compared to 13.09's level. Link to comment Share on other sites More sharing options...
borate Posted February 23, 2023 Share Posted February 23, 2023 Looking more closely, yes - some clipping. See above. It's the same for reloads. Report it, referencing this thread. Link to comment Share on other sites More sharing options...

borate Posted March 7, 2023 Share Posted March 7, 2023 My (and other more sensitive) ears tell me that the audio levels on your project are the same in 13.20 and 13.09. No clipping heard. But the waveform and meters are different. That could change in the future. 13.09 on top, 13.20 on the bottom. 13.09.mp4 13.20.mp4 When these files are opened in Wavepad, the waveforms are the same.
