Waveforms missing from my audio files.

My audio waveforms mostly went flat recently. I think it was after I added AU audio filters to them, but I'm not 100% sure on that. But deleting those filters now doesn't work. Neither does deleting the waveform cache folder in Library, detaching audio, or extracting the audio from the video clips.

Most of my clips have just a flat green line. Occasionally a short snippet of waveform just appears randomly in clips. The rest of those clips are just flat. Those snippets, by the way, don't match up to the actual audio either.

I also switched from Track to Single Thumbnails via the bottom icon but that didn't help either. I've run out of ideas and am hoping I can salvage this project because editing it has become impossible.

I'm running 12.5 Monterey OS and just upgraded from Screenflow 8 to Screenflow 10.0.6.

Any ideas on what I can try next? And also, how can I avoid this in the future?

    We're working on that issue specifically FLOW-11186. Sorry about that.

  • I'm new to the Telestream forums. What does FLOW-11186 refer to? And has the Telestream team figured out the cause yet? Is it the AU filters? Should I be avoiding those for now? And should I consider my current Screenflow project damaged beyond repair? Or do you think the coming fix will repair my waveforms to the point that they are viewable/usable again?

    And how can I make sure I get the fix for this issue as soon as it is released? Is there a way to set Screenflow to automatically check for updates?

     Our investigation reference number. It's how I can check on the status of an issue and report back to a thread.

    The waveform flatline is only cosmetic so it depends on how important the AU filter is. It should still impact the audio the way you want even if you don't see the waveform. Sometimes clearing the waveform cache fixes the issue but that fix is only temporary. It'll keep flatlining after you add the filter until we fix the issue. This is a high-priority fix for us.

  • Thank you for the info. I'm not 100% sure I understand what you mean, so I want to double check. Deleting the filters won't bring my waveforms back, right?

    Like it'd be great if I could delete all the filters, see my waveforms so I can edit the audio clips, and then put the filters back. I'd even be fine with not using the filters at all for this one project if I could get the waveforms back, but none of that is possible, right?

    Because until the glitch is fixed, my project won't show visible waveforms no matter what, correct?

     It may. Not using them avoids the issue. Perhaps add them as a last step.
    Again the issue seems to be only cosmetic. It doesn't seem to have any actual effect on the audio.
