Description MarcusB 2024-05-12 17:54:53 UTC 
Adding various audio effects from the "EQ and Filters" section to Clips on timeline have no impact to the audio output. E.g. Equalizer or "High  Shelf" or "Low Shelf". Even if I set the Filter to amplify a range of frequences extreme, there is no impact.
Tested on .deb, Flatpak and Appimage versions. Problem still exist for me since version 23.08.5 (Previous Versions are Ok. used them for comparing my tests)
Comment 1 Stuart 2024-05-25 20:50:10 UTC 
I can confirm this as well. I recently installed Ubuntu 24.04 and downloaded Kdenlive Version 24.02.2 AppImage from the official Kdenlive website. For some inexplicable reason, most of my audio effects are not working. I can add them to the audio clips, but they have no effect whatsoever.

Here are the steps I’ve taken so far:

* Tried using the Kdenlive version from the Ubuntu repository.
* Tested older AppImage versions of Kdenlive.

Unfortunately, none of these attempts resolved the issue. Below, I’ve attached the terminal output I get when running Kdenlive. Any help or suggestions would be greatly appreciated.

Comment 2 Stuart 2024-06-20 13:59:06 UTC 
Are there any updates on this issue? It has been a month since it was reported, and I still cannot get audio effects to work on Kdenlive, which prevents me from using the software. Is there anything I can do to test or contribute to speed up the bug fix?
