Annoying glitch importing audio (CC 2019)

These are MP3s, but it is not a steady issue in any kind of pattern or circumstance, so I don't think it is a format issue.

I import an audio file, and it is either completely blank, or it skips around. And if it doesn't work right, it NEVER does.

• I can bring it in via Bridge, CTRL+I, or just dragging it in from Explorer

• It can be part of a group of files that I bring - and the others work just fine

• Regardless of what I do after verifying source is fine - delete & reimport, reload, clear caches, restart AE - it remains "wrong"

• BUT - if I change the file name and bring it back into the project, it almost always plays back just fine

I've had issues with reloading files that I have re-rendered outside of AE, but that is usually fixed with a restart of the app. But if an audio file doesn't come in correctly, it never seems to "fix itself"

Am I missing something?

Thanks in advance.

This could be all sorts of things but let me understand what you mean.

When you say it is "blank", are you saying when you hit LL to see the waveform, there is nothing there?

A jumpy playback could be system memory related issue but I'd at least first turn off all other layers with effects and try to play the audio since audio itself tends to be one of the least memory use items.

I suppose the most important question is are we talking about a specific audio track? You mention you can bring it in as a group where others play fine so just wondering but a lot going on there with your description.

Sounds like a combination of corrupted file or some file type support issue.

Yes, there is no wave form when I press "LL," and there is no audio playback at all. In the instances where it skips around, it is consistent - even when prerender is complete. It's not the "slowing down, etc." you get when it's rendering on the fly and can't keep up.

When I talk about groups, it's just adding the files at once. Ironically, the last time this happened to me (yesterday), I had rendered out a single timeline into seven different segments, to bring in as scratch tracks to comp over. One of the seven was "blank." Three others were skipping around. Three were fine. After trying to "reload" in various ways, after confirming that the native files were fine, I just changed the file names of the four, dragged them into the project, and they all worked fine.

It's almost as if AE has something beyond cache that "ruins" a particular file as long as it has the same name in the same project. I have had other times where I would actually alter/re-render a source file and "reloading" wouldn't do anything to change it - I would have to close and re-open AE. With this audio thing, even rebooting the whole computer doesn't fix it.

As Mylenium mentioned, I haven't tried this with WAVs, so I can't say that it has happened with less compressed formats. I do know that it has never happened with MP4s - which I will also use as scratch files when just doing titling.

As far as my system, it's relatively new. Windows 10, i7 8700, 32G RAM, Nvidia 1060 6G

Again, thanks for your input!

If you are having problems with MP3's convert them to video production standard WAV or AIFF files, 48Khz - 16bit linear PCM at a minimum. MP3 files can be compressed in many different ways. Most compression setups work a lot of the time, some kind of work some of the time, and others don't work at all. MP3 is not an industry standard production format for audio.

Impossible to know. You have not provided any info about your system, audio preferences, preview settings etc. and no offense, dismissing issues with MP3s out of hand is not smart. The old adage is still true: AE is lousy at dealing with compressed audio formats. start by converting to AIFF/ Wav, choosing settings that are compliant with AE's capabilities and your audio hardware settings.
