Yellow Clipping in Audio Track.

I have a seperate 2nd music track on track 2.
To adjust volume, I used Tools/Audio Editor/Volume/Dynamic Range Compression

Seem to work fine and the levels decrease when viewing the track display and when listening the volume decreased

However, whenever I close and then later reopen the project, the track display shows the audio levels high again with yellow clipping on the top and bottom.

How do you get the volume changes to stick?

Thanks!

You're doing everything correctly, but you've just found a bug

I can confirm that I see the same issue on my end, and the "good" news is that it's limited to changes made with Audio Editor.

If instead I make timeline changes (like changing the volume of the clip) or use the stand-alone AudioDirector and then send the edited track back to PD, everything works normally when saving and reopening the project.

In your case, is it possible to just lower the volume on the music track? With the audio track height set fairly high you can get a reasonably fine control by clicking on the thin white horizontal line on the clip on the timeline and dragging it down.

You can also open the Keyframe tool with the playhead at the start of the clip then expand the Volume control. Type in the dB level you want (including a negative sign if it will be less than 0) then move the scrubber to the end of the track and type in the same number to set the starting and ending keyframes to the same level. These changes are correctly saved.

If you truly need the dynamic range compression (or any other Audio Editor edits), when you're finished you'll need to produce just the music track to an audio-only format like WAV. You can do that by temporarily removing all other timeline content and producing the clip, or move the clip to the end of the timeline and use the Range Selection tool then Produce Range.

Either way, replace the original music clip with the newly-produced one to lock in the volume changes until CL patches the issue. You can report it directly to them from this page, and make sure you include a link to this discussion. I can also file a report if you prefer.

Excellent response! Very thorough. Thank you. The only reason I used the Audio editor to reduce volume was because I did not know another way. And now you have clearly explained a few different ways. For my simple use, adjusting using the audio white line after expanding the verticle display will work well and Ive tried it. IF you could file the report that would be wonderful. You would provide a much more credible report that they may listen to. Thanks again!

Ok. I actually have some better news! This looks more like a display issue rather than a problem with saving the Audio Editor edits.

Even though the timeline waveforms are reset when the project is reopened, the Audio Editor changes are still intact. This can be verified by both listening to the clip and by reopening it in the Audio Editor, where you can see the waveform change to match the previous edits. When you click OK to exit Audio Editor, the timeline waveform is redrawn correctly.

Here are 3 waveforms I've edited with Audio Editor and saved in the project compared to how those waveforms look when the project is reopened:



In your case, even though the waveform will still show the yellow tips, the dynamic range is right where you set it.

Interestingly, the new Regenerate Waveform for Selected Clip command doesn't bring in the Audio Editor changes and instead simply redraws the waveform at the original audio level.

I've created a test project that gave me the waveform images, and it can be downloaded from here, and I've reported the issue to CL on ticket #CS002254523.

Thanks for that clarification. That confirms my impression that after a retart of PowerDirector that the audio was still at the level I set it with the audio editor when I Iistened but still saw the yellow peak clipping in the graphic. there is so much new for me with PowerDirector that I didnt trust what I was hearing but now I do. Thanks!.

CL just let me know that this issue has been confirmed and they're sending it on to engineering for further investigation.

Thanks for posting! I'm fairly new to Cyberlink... Looking forward to this software update, I really could use a working compressor.

The compression set by Audio Editor works perfectly right now. The only issue is that the compressed waveform doesn't display correctly on the timeline.

Thank you for the quick response! I can't notice any audible difference in the "Preview" or after clicking "Apply"... And the settings won't stick. I've tried on 2 computers to test. Am I missing something? I've attached a pic if it helps.

You have to change the Output Gain slider to have any change in compression. Slide it down by 10dB and you'll easily see and hear the change.

Just be aware that after saving and reopening the project in PD, the waveform on the clip on timeline will show the original (uncompresssed) shape even though the compression is still present.

You're Awesome! I can hear a difference now. Thanks for your support!

The best info I've found is from clicking on the "?" at the top right of the AE window which will bring up the help webpage.

I don't know of any tutorials but I also haven't looked. You might find some on YouTube, in the Cyberlink Learning Center or here on the forum if the linked page info is insufficient.

The incorrect waveform display issue is still present in the latest PD365 19.1.2321.0 release. As before, the actual edits made with Audio Editor are saved and applied correctly but the original audio waveforms will appear on the timeline clips when the project is reopened.
