I did not find an audio editor / audio cutter software for Linux in order to handle audio files like cutting video files in kdenlive. Finally I had the idea, to simply use kdenlive for this purpose. It seems, that I can successfully assemble all kinds of audio files in multiple tracks in kdenlive, can do cutting, rearranging, fading out a music to the next. I can control this editing / cutting work in kdenlive and it plays flawlessly.
But each stereo MP3-file will be reduced to a mono track, when I put it in kdenlive. How can I keep the filse in stereo, when putting them into kdenlive?

Further there is a big problem: when I want to render the stuff to an MP3-file, it produces a non playable file of only 7 kB. Rendering is extremly quick (of course)

I have checked all options for rendering, but cannot find anything wrong there. Does anybody have a clue, what I could to to render in an MP3 output file successfully?

I am running Manjaro-Linux latest and kdenlive 21.12.0, 16 GB RAM, Nvidia GTX1650 with proprietary driver. Video functions in kdenlive are OK!

Yes, you can do almost everything on the audio track.

Huh? The music i import in kdenlive simply stay's stereo. Don't know where you get that 'mono' from. ??

Do you mean render to an mp3 only? Do i understand you right? That's pure audio work. Pure audio work can better be done in audio software as for instance Audacity.
You're also not going to use kdenlive to export a jpeg image, are you?
