What is your audio source format (container) and codec? If not already the case, try to use WAV audio (pcm_s16le). You can also export video only at 60fps, audio only switching to 25fps, and then remux together with FFmpeg?

The only way I have been able to get rid of all audio pops in a 5 minute video is by changing the project profile from 59.9FPS to 25FPS or lower. I am now convinced that it is actually the frame rate of the video that is at fault. Now I use a lot of slide animations which I would like to be rendered at 60FPS in order for them to appear smooth. Is there any way I can export the audio with 25FPS pacing, but still be applicable to a 60FPS source? I am out of ideas, unfortunately.

I typically use up to 30-40 clips for one Youtube Video, which I upload daily. You can check out the channel if you'd like, it's "UFC Digest". Upsampling them to 48khz would be a pain, but I will try a couple upsampled test clips just to check if the pops go away. Right now I have compiled the latest version of ffmpeg git and I am rendering with different profiles and in different formats. I have read on the kdenlive forum that ffmpeg audio thumbnails could be related, seeing as many users have reported the same issue, but a solution was never found. Since Eugen specifically mentioned ffmpeg as the source of the problem, I will make sure to test every possible ffmpeg related scenario, before I move to the next workaround. Thank you all again, for your great insights!
