Still cant figure out audio gltch **HELP**

[csiman]

All things cosidered, the latest version of VS is running great for me, but one major issue i have that i CANNOT figure out or isolate is the audio transition glitch.

Basically, im simple terms, if i fade out an audio clip (.mp3 or .wav) sometimes, randomly, when it gets fully faded out it will replay a microsecond of the adio creating a "blip" or "glitch". I have not been able to isolate it using any of the known fade out controls (the shortcut or manualy fading it with the mixer). I cant isolate it based on file either, sometimes if i remove the audio track and reinsert it the glitch will go away and sometimes it wont. Sometimes it will show up soemwhere else if i fix it in one area. The one thing i have found is that it only happens when i fade an audio file out.

This is the ONE problem in VS that i am currently having and its driving me nuts.

There have been problems in the past regarding audio blips, many discussions on this forum.
Unfortunately there was no definite solution, being random did not help in replicating the problem.

Can I ask that you create a short project that shows these blips, create a Smart Package to share with us. You may need to upload to a sharing site depending on the file size. (One Drive / Google Drive etc.)

Oh as a thought, if you use the programs audio clips are you able to replicate the blips.
Your mp3 audio, are they using the Lame Codec which has caused problems for Video Studio although you do say wav files also show the blips??

I wonder if you have tried fading out by manually adjusting the rubber band downwards. I know you refer to manually adjusting the fade, but in conjunction with the audio mixer. As you know, the audio line is shown running through your project as a straight line running through the middle of the clip. We call this a 'rubber band', I suppose, because it can be adjusted and even spring back into place.

If you go into the audio view (the crotchet symbol above the timeline will turn blue if you select it) and the timeline should show green with the audio being a yellow line running through it. At the beginning of the clip, that yellow line should show a yellow block, and another at the far end of the yellow line where the clip ends. If you go back along that yellow line a short way and position the cursor onto the yellow line and right click, another block should be inserted into the yellow line. You can then go back to the end block, left click and hold the cursor, and drag that block down towards the bottom. That is in effect a manual fade out using the rubber band.

Try that and see if you still get the audio blips.

This is the same topic that you raised in https://forum.corel.com/viewtopic.php?p=399125. To repeat, Audio blips have been a sporadic problem in VS for years, e.g. see https://forum.corel.com/viewtopic.php?t ... t=sporadic

In the following image, you can see that the audio clip is supposed to fade out but VS introduces an audio blip that has to be removed in a sound editor, e.g. Audacity, and then the project rendered again with the new audio track. Obviously this extra step is a waste of time, but unfortunately Alludo isn't interested in fixing such a basic flaw.

I can upload my latest project to google drive and share it if need be.

I have tried it with the quick fade button AND with using the rubber band method, it doesnt seem to matter. The biggest issue is i cant always recreate it, it appears to simply happen randomly.

Hi csiman

Yes, if you can create a project that shows the audio blips then please upload to Google Drive where we can download and test.
I realise the problem can be difficult to replicate, that in turn makes it difficult to fix

VS does not have an .bak project file setting, becuese I just accidentally deleted a project that I had nasty audio distortion in - a few steps that seem to reproduce a hard distortion effect.
2 music and 2 voice tracks use "normalise" effect and mix mp3 and WAV mono files in the timeline - I swapped out WAV file for a MP3 by converting it - it was a very short WAV file, literally 1 second sound effect. once I used audacity to save as mp3, issue went away.

A weirdness I also found at the same time is that if I add a fade-in and then drag the normal volume level to +4db, so that the sound build to loud initially, that the sound effect would instead start playing at +4db and not fade in at all. Did not manage to sort that, the moment you drag the normal level marker up, it would ignore the fade. Hope this helps the developers. Taking normalise off the other clips solved it.

Z mentions removing normalising of audio fixed an issue.
Normalising is described in the user guide (the sound mixer and burning disks) as balancing the audio between several tracks, but generally means set the audio level of a project to a specific level: which sort of negates any loud or soft settings you have deliberately set, esp fades. And for that reason, I never use it and don't recommend it. It may be "easier" to set it and forget any clip-to-clip sound variations, rather than spend a bit of effort getting the sound levels consistent, or set for emphasis (loud or soft), but I found it complicated render results as well as these sort of audio "errata". So, once I'd isolated the sound issues I was having to the use of 'normalise', I simply stopped using any normalise audio functions.
