Audible 'click' at the beginning of any spliced audio

Help

kdenlive-24.05.1-x86_64 Appimage
Ubuntu 22.04.4

There is an audible ‘click’ whenever a new spliced audio file starts playing in the timeline, which also comes out on the render. The audio is a .wav file. Any help appreciated, thanks.

I’ve seen/heard this too, it’s been a constant issue since at least the 19.x releases. Some clips are worse than others for it. In the general case of audio processing, it’s a discontinuity between the previous state of the audio stream and the beginning of a new decode.

In the case of kdenlive (or more likely) mlt I haven’t dug into whether it’s a problem in the codec initialisation, the output pipeline, or the reencoding yet, but I’ve been working around it by muting the first frame of affected audio clips with the keyframable volume effect.

Thanks for the reply. Yes, I’ve been doing a similar thing as a workaround by putting a short ‘fade in’ at the start but I’ll try the keyframe volume as I’m sure that will work better. Do you happen to know of a program that would work on Ubuntu (doesn’t have to be free) in which this doesn’t happen? I’m currently editing together a very quiet music piece and I really need very clean edits as any kind of click or fade is really noticeable. Thanks.

I’ve found a sort of workaround but it might help the developers to identify the problem - the one and only program I’ve found that doesn’t have the ‘clicking’ problem when editing audio is DaVinci Resolve but it’s far too advanced for my needs so I’m going to edit the audio on that, export it, then put the final video together in Kdenlive because I really like the interface and am used to it. I tried Audacity, Olive, Shotcut and Openshot, all on the same computer and operating system, and they all had the same clicking problem. Whatever is different in the way DaVinci Resolve handles audio, it has completely solved the clicking problem.
