Severe audio degradation in Adobe Premiere CC

Hello all.

I recently got Adobe Premiere CC because a recent mandatory Windows update rendered my Adobe Premiere Pro unable to be opened at all.

Much to my dismay, I notice all the audio and videos I upload into the program have the audio severely degraded when playing in the timeline, project panel, and on export regardless of what settings I export them with.

I have tried every fix I have found on the internet but to no avail, and I find myself yet again stumped by a seemingly uncirumventable issue in Adobe.

If anyone has any information on what is happening with my Adobe Premiere CC, it would be vastly appreciated.

Thanks

89? That's unusual. Standard sample rates for source audio are 96 (on the high end), 48, 44.1, 32, 22.5, 11. Standard bit depths are 16 or 8.

What are the exact Sequence and the exact export settings?

Wow I'm sorry. I meant 48khz. I have no idea where in the world 89 came from!

Here are screencaps

Although I don't think the export settings would matter as the exported result looks and sounds exactly as it appears in the program

No confusion on my part ... your example was limited, and there's no way anyone could possible guess what kind of source files you work with if you present no additional information. None of us around here are any more omniscient than anyone else, of course. Remember, it's also nice to be polite with someone taking time from his work-day to help out for diddly squat?

In my experience participating on these forums, many people tend to do a very limited set of workflows, of media types. I do not assume say from the initial example you posted that you would probably also be working with 6k RED files ... which of course, you might. No way for me to know.

I also note that when offered a suggestion from someone with a bit of history helping on these types of things, you called me confused and made it clear you needed to have proved why you should try a very simple diagnostic step that would have taken ten minutes total. The particular file you demo'd could easily have presented audio that PrPro is not comfortable with. Many of the game-play captures do so in audio formats/codecs PrPro does not play well. Hence, my suggestion.

Plus, rather than flailing about, it is more often useful to get as much hard data on a puzzle as possible. As fast as possible. I don't like guessing!

So ... putting a few of your source recordings through MediaInfo, and also doing the same with your PrPro exports of the same recordings ... that could give us hard data to sort this out. What is the actual data of the audio files going into PrPro, and what comes out.

So ... let's look at this screen-grab you posted ... just a part of it:

Look at the source audio sample rate ... the original file ... 11,025 Hz. You can't select a rate that low to export from PrPro, the lowest option I know of is 32,000 Hz.

My guess on that data bit alone is that this is a very highly compressed audio file recorded at a very ... stunningly ... low sample rate. Before coming into PrPro, which of course would have shown immediately in MediaInfo. Ahem.

At that low a sample rate, it might play back ok, sort of ... but trying to re-compress it will show how little there is to work with.

Please use MediaInfo on this and a few of your other clips, and get real data? That would be quite useful.

Okay so I think I described the issue itself to the best of my ability. I'll just add that the audio has much less treble, and timbre altogether. As far as my specs...I'll certainly list what I can

OS: Windows 10

Processor: i7-3630 QM CPU @ 2.40 GHz 2.40 GHz

Installed memory: 8.00 GB

System type: 64-bit Operating System, x64-based processor

Graphics Card: GeForce GTX 660

Premiere version: Adobe Premiere Pro CC 2017 V11.0.1

Failed attempts to resolve:

Started new project multiple times

Uninstalled and reinstalled

Used a multitude of media with different formats ie MP4, AVI, MP3 etc

Restarted PC

Cleared media cache folder/renamed/moved to a different location

Used Media Explorer to import rather than standard direct or drag and drop method

Switched Mercury Playback from GPU to CPU, and back again

What I cannot do:

Anything with drivers!! I have lost too many computers to drivers (yes, drivers alone can kill computers. I am living proof of that!) and I cannot risk another driver calamity.

If any other info is needed please let me know and I'll do my best to retrieve it.

Thanks so much in advance!

You didn't list or show any of your audio settings in the audio and audio hardware tabs of your preferences dialog.

Please post in your reply a screen grab of each of those two screens.

Totally off-topic. I just registered for forums.adobe.com and this site is so badly organized that I simply can not figre how to post a new thread/question. I seem to be only capable of replying to other posts hence I am writing here. I have a question about photoshop processing. Can anybody direct me via a url to a page where I can post my question in which I want to ask for advice on how to do something in Photoshop CC. Thank you in advance.!
